Perth Taxi Unmet Demand Survey 
Executive Summary
LVSA were commissioned by Perth & Kinross Council to undertake a taxi
unmet demand survey.  The study is intended to fulfil the requirements set
out in the Civic Government (Scotland) Act 1982 (CGSA) and Best Practice
Guidance (BPG) issued by the Scottish Government and relevant case
history in regard to unmet demand.
Within the Council licensing area, the council maintains a limit regarding
the number of taxis which may be licensed in Perth.  The current limit is set
at 80 taxi vehicles in Perth.  There is no limit to the number of taxis which
may be licensed in other areas around Perth and Kinross.
Data has been collected through consultation with stakeholders, the trade
and members of the public.  In addition, observations of activity at taxi
ranks were undertaken to record volumes of taxis and passengers using
each rank and whether any passengers had to wait for taxis to arrive at the
ranks.
The 2024 survey is the latest in a regular series of surveys commissioned
by the Council.  The last two surveys were conducted in 2021 and 2017.
Taxi demand in 2021 was heavily influenced by the aftermath of the Covid-
19 pandemic.  Since 2021, the level of passenger demand had increased.
The total volume of observed hires of taxis from the ranks in Perth was
lower in 2024 than that observed in 2017.  However, despite the reduced
volume of hires through the ranks, the number of people who had to wait
for a taxi to arrive at the ranks in 2024 was significantly higher in 2024,
than in 2017.
There has also been an increase in the number of taxis in the fleet in Perth
in 2024, compared with 2017.

The purpose of this survey is to identify whether there is sufficient
availability of taxis at the ranks to meet the level of demand.  
The result of the survey is a clear indication that there is not sufficient
availability of taxis at the taxi ranks, to meet demand.  There is significant
unmet demand for taxis.

Page 4

Perth Taxi Unmet Demand Survey 
The number of hires obtained from ranks has fallen dramatically since 2017. 
The hires observed at ranks in 2024 were around 48% of the level observed
in 2017.  The number of taxis in the fleet has increased by 6.7%.  Despite
more taxis and less hires taking place at ranks, the number of people who
had to wait for taxis to arrive at the ranks had increased by 108%.  
Clearly, the way in which taxis operate has changed.  The way in which
people hire licensed vehicles has also changed, with more people pre-
booking hires for immediate travel.
The situation in 2024, compared with 2017, was that use of the ranks has
reduced, passenger waiting has increased and the number of taxis in the
fleet has increased.  However, the increase in the number of taxis has not
addressed the increased passenger waiting and hence the level of unmet
demand is significant.
Options open to the Council to address the shortage of supply are limited. 
A change in fares could be considered, however the level of taxi fares and
structure of the taxi fares table are outside the remit of this survey.
There remains only the option to increase the number of licences, either by
increasing the cap on licences, or by removing the cap altogether.  
If the cap were to be increased, it would require a large increase to result
in the changes needed to address the level of unmet demand observed.
It is recommended that the cap on licence numbers is increased by 24
licences.  The issue of licences should follow current policies for additional
taxi licences.

1 Perth Taxi Unmet Demand Survey
1 General introduction and background
Perth & Kinross Council is responsible for the licensing of Taxi and Private
Hire Cars operating within the Council area. It retains a limit on the number
of Taxi vehicles licensed. 
This study is intended to fulfil the requirements set out in the Civic
Government (Scotland) Act 1982 (CGSA) and Best Practice Guidance (BPG)
issued by the Scottish Government.  
Current taxi, private hire and operator licensing is undertaken within the
legal frameworks set by the Civic Government (Scotland) Act 1982 (CGSA). 
Leeds University Institute for Transport Studies developed a tool by which
unmet demand could be evaluated and a determination made if this was
significant or not. The tool was taken forward and developed as more
studies were undertaken. Over time this ‘index of significance of unmet
demand’ (ISUD) has become established as an industry standard tool to be
used for this purpose. 
In general, the determination of conclusions about significance of unmet
demand must take into account the practicability of improving the standard
of service through the increase of supply of vehicles. It is also important to
have consistent treatment of authorities as well as for the same authority
over time.
In conclusion, the present legislation in Scotland sees public fare-paying
passenger carrying vehicles firstly split by passenger capacity. All vehicles
able to carry nine or more passengers are dealt with under national public
service vehicle licensing. Local licensing authorities have jurisdiction over
vehicles carrying eight or fewer passengers. 
These are split between taxis which are alone able to wait at ranks or pick
up people in the streets without a booking, and private hire who can only
be used with a booking made through an operator. If any passenger uses a
private hire car without such a properly made booking, they are generally
not insured for their journey.

2 Local background and context
The authority has a current population of 153,000, based on Scottish
Government statistics. 
All licensing authorities have full powers over licensing the vehicles, drivers
and operators serving people within their area. Perth & Kinross Council has
chosen to utilize its power to limit Taxi vehicle numbers in Perth. 
Throughout other areas within Perth and Kinross, there is no limit to the
number of taxis.
Perth & Kinross Council undertakes regular review of its policy to limit Taxi
vehicle numbers in line with the BPG.  
Table 1, Table 2 and Figure 1 illustrate the fleet composition for the licensing
authorities in Scotland.  The authorities are arranged in order of increasing
licensed vehicles per 1,000 population and increasing proportion of licensed
vehicle drivers per licensed vehicle.  
Licensed Vehicle numbers and proportions are largely based on 2023 figures
and Mid 2023 population data.

Whilst the comparison of licensed vehicles against population provides a
useful metric, it should be noted that population size is not the only driver
of demand for licensed vehicles.  Other aspects such as visitor numbers,
car ownership/availability, levels of business travel, the presence of large
rail termini and airports can have a significant influence on the demand for
licensed vehicles.  For example, Renfrewshire has a large proportion of
licensed vehicles per head of population.  A significant influence on the
demand for licensed vehicles is the fact that Glasgow Airport lies within the
boundary of Renfrewshire and many of the licensed vehicles servicing the
airport are licensed by Renfrewshire Council.  Glasgow and Edinburgh also
have relatively high levels of licensed vehicle provision per head of
population.  Much of the demand is driven by the level of non resident users
in each city.  Tourist and leisure visitors, business visitors and passengers
in transit from the airports and major rail stations all contribute to demand,
in addition to demand generated by residents in each Council area.
Both taxis and private hire cars are often associated by the public as
vehicles which are commonly hired by any member of the public for
immediate travel, often for relatively short local trips.  However licensed
vehicles also fulfil other functions such as limousine services, airport
transfers, tourism services, contract hires and corporate travel.  As such, in
some licensing areas, such vehicles rarely or never are used for immediate
hires by the general public.  Larger cities tend to have higher levels of
demand for such services and hence a greater number of licensed vehicles
in cities may be used for such non-immediate hire purposes, compared with
smaller and more rural areas.
In addition to licensed vehicle numbers, it is prudent to consider the number
of drivers licensed to drive these vehicles.  In Perth & Kinross, taxi drivers
and private hire car drivers may drive both taxis and private hire cars. 
Some licensing authorities limit private hire car drivers to only driving
private hire cars.
Higher ratios of licensed vehicle drivers to licensed vehicles may imply more
intensive use of each vehicle.  Consequently, the capacity of the fleet is
enhanced with more extensive use of vehicles for multiple shifts.  Fleets
with a higher ratio of drivers to vehicles tend to be more capable of catering
for larger fluctuations in demand, such as increased demand on Friday and
Saturday nights.  Table 2 provides the ratio of licensed vehicle drivers to
licensed vehicles, ranked by the ratio of all drivers to all licensed vehicles,
based on 2020 Scottish Government data.  The ratio of all licensed vehicle
drivers to all licensed vehicles for Perth & Kinross was 1.74.  This is higher
than the Scottish average.

Fares comparison
Private Hire and Taxi Monthly magazine publish monthly league tables of
the metred fares for taxis in Licensing Authorities in the UK.  The Tariff 1
fares for a two mile journey (distance costs only) are compared and ranked. 
The lower the ranking (number), the more expensive the journey,
compared with other authorities.  The December 2024 table indicated that
the fares in Perth & Kinross were ranked 291 out of 362 authorities listed. 
This indicates that taxis in Perth & Kinross are cheaper than for most
authorities. A comparison of the fares ranking of Scottish authorities is
presented in Table 3

Perth taxi ranks
Within Perth & Kinross, Perth is defined as a separate taxi licensing zone,
with a limit of 80 taxis licensed within the zone.  
Five taxi rank locations in Perth were surveyed from the morning of
Thursday 20th June 2024 to the morning of Sunday 23rd of June 2024
These locations were:
1 Murray Street
2 Railway Station
3 South Street (outside Tesco)
4 South Street (outside Loft)
5 Pomarium Street, near the bus station
Rank surveys
Surveys were undertaken using video cameras which recorded activity at
the ranks from Thursday to the following Sunday morning.  The video
footage of each rank was processed to assess the level of usage of each
rank and to record any incidences of passenger waiting.  Footage was
recorded from 7:00 on Thursday 20th June 2024 to 7:00 on Sunday 23rd
June 2024.  
Overview of observations
During the course of the survey, some 943 taxis were observed departing
the ranks with passengers.  This total was more than the 774 vehicles
observed departing the ranks with passengers during the 2021 survey,
However, the observed total was less than the 1,959 vehicles which were
observed departing the ranks, with passengers during the 2017 survey.  
The number of hires observed during the 2024 survey equates to
approximately 12 hires per vehicle (with a fleet size of 80) over the three
days of observation.  
The proportion of taxis which left the rank empty was approximately 33%. 
This is higher than the 24% proportion observed during the 2017 survey,
but lower than the 40% observed during the 2021 survey.  
Taxis normally leave ranks empty for a variety of reasons.  These include
moving to another rank, having waited unsuccessfully for a hire, or leaving
the rank to service a booking.  Many of the taxis which departed the railway
station rank empty, departed after a train had arrived and not all waiting
taxis were hired.  Rather than wait for the next train, it was common for
remaining taxis to leave the rank.

Page 15

9 Perth Taxi Unmet Demand Survey
Most of the taxis departing the rank empty, were from the Murray Street
rank.  It is assumed that a significant proportion of those departures were
in response to a booking, rather than moving to another rank. Generally,
these departures occurred when other ranks were not active, so were
unlikely to attract taxis from the Murray Street rank.  This assumption was
corroborated by feedback from the trade.  
During the course of the surveys, no passengers were observed, who used
a wheelchair.
Many incidences of passenger waiting were observed.  Out of 1,451
passengers observed using Taxis, 331 (23%) had to wait for a taxi.  It
should be noted that not all passengers observed waiting for a taxi, actually
boarded a taxi.  40 intending passengers left the ranks in frustration, having
waited at the rank for a taxi to arrive.  For comparison, during the 2021
survey, 159 passengers (6%) of 2,730 passengers were observed waiting
for a taxi to arrive at a rank.
The maximum wait time observed during the 2024 survey was39 minutes
30 seconds.
The average waiting time for all passengers who had to wait for a Taxi,
during the 2024 survey, was 5 minutes and 30 seconds.  This was lower
than the average wait times observed during the 2021 survey, which was
12 minutes 31 seconds.  The average waiting time for all passengers who
had to wait for a taxi during the 2024 survey was significantly longer than
the observed average wait time during the 2017 survey, of 2 minutes and
8 seconds.  
During the 2024 survey, the average waiting time for all passengers,
including those who didn’t have to wait, 1 minute 14 seconds.  This
compares with the 2021 waiting time of 3 minutes 25 seconds.  During the
2017 survey, the average wait time was significantly lower, at 7 seconds. 
Total volumes of passengers and taxis through each of the ranks is
summarised in the following tables.

duration, for the profile to be considered highly peaked.  This assessment
is used to determine one of the variables in the calculation of the Index of
Significance of Unmet Demand. 
Estimation of the number of taxis working from ranks
The rank observation data was processed to provide an estimate of how
many taxis were working from the ranks during each hour of the survey. 
The nature of work undertaken by most of the taxis in the fleet is a mixture
of rank hires and pre-booked hires.  Therefore, not all working taxis were
working from the ranks at any given time, some were undertaking pre-
booked hires and were not available for hire from ranks.
The estimate derived is the number of full time equivalent taxis working
from the rank, rather than a count of how many distinct taxis were observed
at some point during each hour.   i.e. how many taxis spend each hour
either conveying passengers from the ranks or waiting at the ranks for a
passenger.  Typically, at peak activity levels, taxis, which pick up only from
ranks, may undertake around 3 to 5 hires per hour, if passengers are
queued at the rank.  At other times, the number of hires is lower and taxis
wait at the ranks between hires.  However, in Perth, some taxis undertake
both rank hires and pre-booked hires and some undertake only pre-booked
hires.  A common scenario would be that a taxi may pick up a hire from a
rank, then pick up one or more hires from non-rank locations, through pre-
booked hires.  Under this scenario where taxis may work from a rank for
part of an hour, only that fraction of the hour is counted towards the
aggregate taxi equivalence.  Figure 7 presents the aggregate equivalent
taxis working from ranks and excludes any other taxis either not working
during that hour, or undertaking pre-booked hires.
The following examples illustrate how equivalences are determined, within
a single hour.  
In this example, a taxi waits at a taxi rank for 5 minutes, then picks up a
fare and travels for 10 minutes to the destination.  The wait time at the
rank and the duration of the trip hired at the rank, both count towards rank
based working time.  The taxi then is hired to pick up passengers from non-
rank locations through pre-booked hires.  These hires take up the rest of
the hour.  The taxi spent 25% of the hour on rank based hires, either wating
for a hire or conveying a passenger from the rank.  Therefore, in the taxi
equivalence calculation, the taxi would count as 0.25 of a taxi working solely
from the rank.  
Alternatively, we consider a taxi which waited at a rank for 5 minutes then
picked up a fare, which took 10 minutes to the destination, then returned
to the rank 10 minutes later, waited 15 minutes at the rank, picked up
another fare from the rank and travelled 10 minutes to the destination, then
returned to the rank 10 minutes later.  In this situation, the taxi was

Page 20

14 Perth Taxi Unmet Demand Survey
engaged in waiting at the rank, or travelling to or from the rank, for the full
hour.  Hence, under this scenario, the taxi would count as a full equivalent
taxi working solely from the rank.   
Figure 7 - Estimate of taxis working from the ranks (Perth)
The number of taxis working from the ranks peaked mid afternoon each
day.  There were more taxis working from the ranks on Friday and Saturday
nights than on Thursday night.  However, the number working at night from
the ranks was generally lower than in the afternoon, each day.
As discussed earlier in the report, some taxis obtain some of their hires
through pre-booking, either directly with the driver or through a booking
office or web site.  Consequently, if some drivers are undertaking pre-
booked hires, they would not be seen to be working from the ranks at these
time.  Therefore, the number of taxis working from the ranks as indicated
in Figure 7 are unlikely to reflect the true total of all taxis working during
each hour.

4 General public views
It is very important that the views of people within the area are obtained
about the service provided by licensed vehicles. A key element which these
surveys seek to discover is specifically if people have given up waiting for
taxis at ranks (the most readily available measure of latent demand).
However, the opportunity is also taken with these surveys to identify the
overall usage and views of taxis and Private Hire Cars within the study area,
and to provide an opportunity for people to identify current issues and
factors which may encourage them to use licensed vehicles more.
Such surveys can also be key in identifying variation of demand for licensed
vehicles across an area, particularly if there are significant areas of potential
demand without ranks, albeit in the context that many areas do not have
places apart from their central area with sufficient demand to justify taxis
waiting at ranks. 
An online survey was used to gather opinions from members of the public.
The results of the survey are presented in this chapter.  Not all questions
were answered by all respondents.  The total number of answers to each
question have been presented in this chapter along with percentages
relating to the total responses to each question, rather than a percentage
of all people interviewed.
Perth public attitude survey results

Have you experienced problems in obtaining a Taxi in Perth in the last three
months?     
If yes, approximately what time and day of week did this occur?
348 responses were received to this question.  Responses included a broad
spectrum of days of the week and times of day.  Many respondents indicated
that at most times of day and days of the week, there were difficulties.  A
slightly more popular response indicated that there was particular difficulty
obtaining taxis during weekday mornings and afternoons, particularly
during ‘school run’ times.  Other popular responses indicated that Friday
and Saturday nights were particularly difficult times to obtain a taxi.

If the cost of Taxi fares was to decrease by 10%, do you think this would
lead to you using Taxis more frequently? 
Are there any locations where you would like a new Taxi Rank?   
Respondents were asked to specify locations where they would like to see
new taxi ranks.  Some respondents indicated general locations such as ‘the
City Centre’ or ‘Supermarkets’ or ‘retail parks’.  
Some popular suggestions for specific locations were:
Broxden Park and Ride - Justification was given by some that intercity buses
which call at the park and ride, don’t go to Perth Centre and taxis would
connect to the city centre.
Concert Hall – Close do daytime shopping and evening venues.
High Street – A central location.
George Street – Close to night time venues
Tay Street – Close to night time venues.

Page 31

25 Perth Taxi Unmet Demand Survey
Additional suggestions were made for taxi ranks in locations outside Perth,
in other locations in Perth & Kinross. 
Taxi ranks work effectively if drivers have a reasonable expectation of
obtaining a fare from the rank.  Rank locations which generally work best
are located where taxis can reach a rank as part of a route returning to
another rank.  For example, if drivers operate from the Murray Street rank,
they may return to the Murray Street rank after dropping off a fare.  If the
route back to the Murray Street rank involves passing another rank location,
the driver may see if there are any waiting passengers, or indeed if the taxi
queue is short and consequently decide to wait at that rank, rather than
return to the Murray Street rank.  In this way, supply is better balanced
across ranks.  Using an alternative example, if a new rank is placed in a
location which requires a detour of several minutes to visit the rank, drivers
are less inclined to visit the new rank ‘on spec’ and are more likely to invest
the time required for the detour, to return to the established rank at Murray
Street and wait in the taxi queue.
At present, the Murray Street rank is effectively the only rank operating at
night in Perth.  Several of the suggestions made were aimed at establishing
a new night time rank which is closer to some of the night time economy
venues than Murray Street.  The rank outside, on South Street was
identified as one which several respondents would like to see “ reopened”. 
In the past, the rank in this location has been a busy night time rank. 
However, the presence of parked vehicles at night on the rank space has
prevented the use of these spaces as a taxi rank in recent times.   
Are there any existing Taxi ranks that you would use more often if Taxis
were more reliably found there? 
Respondents were asked which ranks they would use.  They indicated all of
the existing ranks which are in common use.

Page 32

26 Perth Taxi Unmet Demand Survey
Have you wanted to hire a Taxi in the last three months at a taxi rank or
by hailing and given up or made alternative arrangements for travel
because none were available? 
Whilst 73.8% of respondents indicated that they had given up at a taxi
rank, the respondents were asked a supplementary question to establish
whether the incident occurred at a valid taxi rank location or at another
location.  97.8% of those who indicated that they had given up, stated that
this had occurred at valid rank locations in Perth.  The remainder of
responses suggested that they had given up on pre-booked hires or at
locations which were not valid taxi ranks, including locations outside Perth.  
Consequently, the valid response for those who had given up waiting was
72.2%.  This statistic is used in the calculation of the Index of Significance
of Unmet Demand. 
Have you wanted to book a Taxi specifically, as opposed to a Private Hire
car, by telephone, app or online, for immediate travel, in the last three
months and had to make alternative arrangements because a Taxi was not
available within a reasonable time?

What features of Taxi services in Perth & Kinross that you feel are
particularly good?  
The most popular response was that the drivers were knowledgeable and
friendly. 
What would encourage you to use Taxis more frequently?
The most popular response was increased availability. 
Do you, or anyone with you on a taxi journey, within the last 3 months,
have a mobility or visual impairment or travel in a wheel chair? 
The most common impairments were mobility impairments, some of the
passengers with mobility impairments were also wheelchair users.  There
were also a range of other mobility impairments identified, including
breathing difficulties and difficulties with joints.
Respondents also identified visual impairments, hearing impairments and
learning disabilities, amongst other impairments. 
Did this cause any difficulties when travelling? If yes, please describe.
Around 8% of those respondents who indicated an impairment, indicated
that the impairment did not cause any difficulties.  The remainder indicated
a range of difficulties, which included the following, which are listed in
reducing order of frequency:
• Difficulty getting in and out of vehicles, including identifying that cars
are too low to get in and out of easily and larger vehicles are too
hight to get in and out of easily.

Page 34

28 Perth Taxi Unmet Demand Survey
• Lack of wheelchair accessible vehicles.
• Difficulty with walking the distance to the taxi rank / pick up location
or walking from the taxi drop off location.  This is an issue when
travelling to pedestrianised areas.
• Difficulty with standing for extended period whilst waiting for a taxi
to arrive.
• Difficulty fitting walking frame / wheelchair into the vehicle. 
How would you suggest these difficulties could be reduced for travel by taxi
in Perth?

Are you: 
What age range do you fall under? 
Do you have any other comments, suggestions or points to make
which are not covered in the earlier questions?
Responses included the following statements: 
Bring in Uber
Taxis are expensive and unreliable! Uber would help with competition and
is much safer 
Make both the bus and taxi service more accessible at night for times. 
Lack of buses now means people need more taxis and this has not happened
meaning people having to walk home late putting themselves in vulnerable
situations.

Page 36

30 Perth Taxi Unmet Demand Survey
Taxi’s are expensive to rural areas, and no buses available either
Rural areas not covered
Tariff prices should also be reviewed, during the cost of living crisis, those
seemed to have risen; this could have a negative impact on companies cash
flow resulting in potential closure. PKC could help these companies out? 
Transport generally in Perth is terrible.  Availability, frequency and high
costs.  It is easier and more convenient to drive these days.  There’s no
encouragement for people to use services.  
The reinstatement of rural bus services would reduce the requirement for
taxi services. Students, elderly and the disabled population have been
particularly affected by these cuts along with opportunities for
socialising/visiting areas in Perth without their own vehicle. A communal /
shared travel taxi service option would be good in rural areas where
bookings can be shared at the discretion of the taxi driver and customer to
improve efficiency, reduce costs, reduce the carbon footprint and, I suspect
also, reducing wasted time for the taxi firm traveling to more rural areas.
Reliable availability of a taxi service to rural communities would be
beneficial.
Look at who holds the plates in Perth. If they are not being used to be of
service to the community then they should be revoked and given to taxi
companies who will be of service. Perth also needs Uber. I've just spent 3
weeks in the U.S.A and the service was brilliant and inexpensive. 
Uber would benefit residents in Perth & Kinross. Taxis between outlying
areas are charged from Perth making this travel almost impossible. The
uber concept provides a more customer focused and cost effective
approach. 
Taxis must improve. It’s 2024!
My daughter and her pals have struggled to get a taxi home at night and
ended up having to walk 3-4 miles home in the early hours of the morning,
this is not a safe thing to do for a young women. 
It's having an impact on people going out socialising when you can't
guarantee getting home at the end of the day 
Footfall in the city centre from surrounding areas of Perth and outskirts of
Perth may be improved if availability and service improved. I now travel via
bus from Broxden to travel outside of Perth for dinner/drinks, or drive out
with Perth, to avoid having issues getting home late at night as I am unable
to get a taxi and buses within the city centre do not run late enough. I
previously lived in Dundee and never had availability issues with Taxi’s,
there were far more ranks and far more taxis around town late at night and
at peak times.

Page 37

31 Perth Taxi Unmet Demand Survey
Please make sure companies have accessible taxis on in evening and
weekends it would make the world of difference.
There are so few taxis, there is little competition so price wise you are over
a barrel.
Please get more taxis
Just that in the big cities Uber has been extremely useful and affordable
and extremely easy to get a taxi with them
I think our taxi provision is not as bad as some people suggest. I travel and
often find other cities more frustrating than Perth 
It is unsafe for women to be waiting hours for a taxi possibly attempting to
walk home alone after a night out due to no taxis being available leaving
them vulnerable 
With a limited bus service now especially after 8pm Perth needs more taxis
especially later on in the evening
The lack of availability is starting to get dangerous.  People are being forced
to walk distances late at night because of no other option.  As a young
woman, that makes me feel unsafe.  It's not much better being forced to
stand at a rank for at least 30 minutes if you are on your own.  
Our bus service is awful with last bus from city centre to Oakbank at 8pm.
Can’t have a night out without someone driving or trying to find a non
existent taxi
Some taxi drivers shouldn't have their badges. When they jump red lights
all time 
Taxi services refuse to pre book taxis on Friday/Saturday nights when it’s
really busy but this puts hospitality workers in danger having to walk home
alone. Provisions should be put in place to ensure that cars should be
available to book in advance for staff. 
The lack of taxis is stopping us from going out later or staying out - we tend
to leave early due to the lack of taxis to get home 
Would love uber in PKC. Very poor public transport from Luncarty, especially
on Sundays. Also no buses from Broxden park and ride on Sundays so rely
on taxis there. A rank there on Sundays? 
An app for checking the availability of taxis, from all the companies
operating in Perth, at any time day or night
Need more taxis on a sat night put me off going out on sat night as don’t
want to walk home alone.

Page 38

32 Perth Taxi Unmet Demand Survey
In a town that you can walk across in 60 minutes, anything more than a 5
minute wait for a taxi is unacceptable. 
Taxis are unavailable during school pick up and drop of times, as they all
seem to be on contacts.
Demand for taxis wouldn’t be so bad if a late bus was run on Saturday
nights to get people home safely.  We are supposed to be a city.
Taxi drivers in Perth are generally very good and deserve as much support
as possible to maintain this
Due to lack of available taxis at ranks I now phone in advance. It would be
nice to be able to be spontaneous and know if I am out that I have a safe
and reliable way home by taxi
It would have been helpful for you to include the question, where you hail
a taxi as you’ve omitted visiting an office
Think I've said it all. It's a disaster. Get a school bus and make more taxis
available for disabled and just people in general. 
Only issue I have is the lack of taxi coverage. Having to wait up to 30 mins
or even an hour for a taxi 
Improvements to the bus service would reduce demand to a manageable
standard for taxis. Lack of evening buses impacts on the local economy...if
you live out of Perth it's cheaper to stay in a hotel than get a taxi home
I also think there should be more female, taxi drivers.
Safety paramount and taxi ranks could do with a police presence at
weekends especially Mill Street [Murray Street] 
Taxi services in Perth have been the same for 40 year, it’s needs to be
updated to help attract people to Perth 
Please remove some School contracts. Owners make money make enough
money from them leaving no requirement to work evenings or weekends. 
Please bring back the no 8 Hillend bus after 8pm evenings, disgraceful
cutting this.  Used to be bus from town 9.15pm, 10.15pm + 11.15pm now
last one 8pm!!
Some taxi ranks using apps I feel cancel bookings unexpectedly. Please
don’t provide an app if it’s not linked to main booking system 
It’s going to have a knock on effect of other areas of the city such as
nightlife as many people aren’t going out as they know they will have to
wait well over an hour to get home, this is made worse by the change in
bus timetables by stagecoach. Having more taxis for the last train of the
night for similar reasons; people may have been traveling all day and finally

Page 39

33 Perth Taxi Unmet Demand Survey
get back to Perth then still have to wait over an hour to get home. I have
had to go to work in Dundee at short notice and tried to call a taxi and been
told no because they can’t spare any cars for that long a journey 
Support and encourage taxis for evening and weekend work 
A notable reduction in bus services and taxi availability has resulted in more
of our social and entertainment expenditure being in Dundee/Broughty
Ferry and Glasgow areas as it is now, remarkably, easier to get a bus home
from these places than it is to get a bus or taxi home from Perth city at the
end of a night.
At times the service in Perth is an absolute disgrace. I have missed
appointments because I couldn't get taxis at the rank. Most of the time it is
completely unreliable 
Perth council need to sort out the available transport into the CITY centre.
It’s a disgrace and I’m surprised businesses can survive when’s it’s so
difficult for people to access them by public transport or taxi service. It’s
embarrassing. 
I feel taxis are very expensive as it is, please don’t look to increase them
again. In comparison to other cities our starting price is quite high.
Yes, People of Perth and surrounding areas do not venture into the city as
they cannot get home after 9pm at the weekend etc by the way buses are
the same.
Maybe a OAP rate for older 
Some taxis and drivers are better than others in keeping their vehicles
clean.
Most drivers are great polite and courteous 
PKC take account of high number of elderly disabled wheelchair users who
need taxis for morning and afternoon appointments. Consult via lunch/tea
clubs, retirement living, etc. Stop issuing WAV licences to those who don't
have WAVs or drivers, get professionals in to train WAV drivers on 2 day
courses, not charity on useless 2 hour course
The safety of people in town centre walking to main rank, especially in
evening needs sorted out.
Bring back late night buses and add Ubers, then there won't be long waits
at the too few taxi ranks.  
Just would be nice for me or my daughter to be able to get home safely
after a night out.

Page 40

34 Perth Taxi Unmet Demand Survey
I have a young daughter and would like taxis to be readily available for her
and her friends when required. I would be more reassured if the taxis were
council licensed and drivers thoroughly checked to maximize safety of
vulnerable people. Clear pricing structure.  
Think drivers should have some kind of uniform to smarten them up and
this would uplift the view of the city to tourists as well 
Certain cars are extremely unclean - high standard of cleanliness should be
ensured. Spot checks to monitor.
The questions about what factors determine taxi use, e.g. price, are often
not relevant. I don't have a car so sometimes need to use a taxi as there
are no other options for some journeys. 
Improve drivers customer communication skills- in general they don’t say
a word to you the whole journey
Fill the gap in unmet demand in taxis by getting the late buses back!
Usually Always friendly taxis drivers 
Twice have had to walk from Tulloch to Scone on a Saturday night as
phoned for a taxi and no taxis available. Even after walking to the rank on
Mill Street [Murray Street] and still no taxis.
Why not have taxis at railway station later at night when it is known trains
are arriving eg after a well publicised sporting event/music event in
Glasgow/Edinburgh and fans arrive back to Perth in dark and there are
never any taxis there
The lack of taxis is proving unsafe for youngsters who are trying to get
home from a night out. Hanging around in the streets at the early hours in
the morning is resulting in people feeling frustrated which is leading to
fighting and it is a huge danger for people who are on their own.
New drivers should be taught personal boundaries and to behave better
with women. 
It's quite worrying when my daughter is on a night out as getting a taxi is
a nightmare.  Also the rank needs to be policed better
Due to the reduced bus service in the evenings to the Oakbank area the
taxi service is invaluable if you want people to support the
theatre/restaurants and local businesses to keep Perth city centre thriving

5 Key stakeholder consultation
The following key stakeholders were contacted in line with the
recommendations of the Best Practice Guidance:
• Supermarkets
• Hotels
• Pubwatch / individual pubs / night clubs
• Other entertainment venues
• Restaurants
• Hospitals
• Police
• Disability representatives
• Rail operators
• Other council contacts within all relevant local councils
Comments received have been aggregated below to provide an overall
appreciation of the situation at the time of this survey. In some cases there
are very specific comments from stakeholders. The comments provided in
the remainder of this Chapter are the views of those consulted, and not that
of the authors of this report. 
Our information was obtained by telephone, email, letter or face to face
meeting as appropriate. The list contacted includes those suggested by the
Best Practice Guidance.  Our target stakeholders are as far as possible
drawn from across the two licensing areas.
For the sake of clarity, we cover key stakeholders from the public side
separately to those from the licensed vehicle trade element, whose views
are summarized separately in the following Chapter.
Supermarkets
It is not generally possible to contact individual supermarkets by telephone. 
Therefore, where possible, individual supermarkets were visited and staff
at the customer service desk were asked about taxi services.  Feedback
from supermarkets indicated that mobile phones or dedicated taxi phones
were generally used to book travel by licensed vehicles.  None of the
customer service desk staff were aware of any notable issues with the
availability of licensed vehicles for customers.  However, use of licensed
vehicles was not a matter which they were generally involved with.  It was
rare that customer service desks were involved in helping to book a licensed
vehicle.  Some staff did venture opinions, based on personal experience,
that reliance on taxi availability at the ranks in Perth was likely to result in
a wait for a taxi to be available.  It was better to try booking by phone, half
an hour or so, before you were likely to need a licensed vehicle.
Hotels
None of the hotels contacted indicated that they had a Freephone facility
for any particular private hire company.  Most guests, if they needed a taxi

Page 42

36 Perth Taxi Unmet Demand Survey
would call and book one themselves.  There is often information provided
by the hotels, with some local numbers.  If guests made it known that they
were intending to use taxis during their stay, staff would sometimes advise
them that they should book their return trip in advance, in order to
maximise the chance of obtaining a licensed vehicle on time.  
Pubs Clubs and Restaurants
A selection of public houses were contacted to seek their views on the
availability of licensed vehicles.  In some cases, door staff were contacted
for a face to face discussion.  In general, there was an awareness that
obtaining a licensed vehicle by booking with a booking office, or obtaining
one at a rank, would generally involve a wait at busy times.  This was
especially the case late at night.  
Central Perth venues generally felt that if all else fails, waiting at the rank
at Murray Street would guarantee a taxi, although there may be a
significant wait to get to the head of the queue.  
There was some feedback that a combination of fewer venues and lack of
night time transport was attracting fewer people into Perth from outlying
areas.  Fewer venues seemed to result in less ‘critical mass’ of alternative
pubs clubs and restaurants, to tempt people into Perth.  This, coupled with
reduced public transport availability through both buses and taxis had
reduced visitor numbers.  Some felt that Perth residents were going to other
localities which offered greater variety of night life.
It is thought that some people visiting night time economy venues booked
a taxi home, in advance, with an arrangement made directly with the driver.
Hospitals
People normally made their own arrangements for taxis.  Licensed vehicles
frequently set down and pick up from the hospital.  Occasionally, it has been
noticed that some people may have to wait for extended periods for their
transport to arrive.  Generally there are no issues worth noting.
Police
Police Scotland indicated that they were aware that delays can occur at pub
closing times and generally late at night.  There was no indication that this
was creating a particular problem with public order. 
Disability
A sample of care homes were contacted to ask if they use licensed vehicles
and if so, what level of service they received.  Generally there were no
issues identified by care homes.  The majority of care homes use regular
providers and pre book a licensed vehicle if they need a wheelchair
accessible vehicle (WAV).  Some care homes use a regular supplier, even
though they may not have a frequent need for licensed vehicles.  This

Page 43

37 Perth Taxi Unmet Demand Survey
approach seems to accord some degree of priority of service.  Their regular
suppliers normally had a suitable vehicle available.  
Consultation was undertaken with representatives of elderly and disabled
user groups and Council representatives who deal with taxi contracts for
school and other special need transport.
The responses are summarised as follows:
• With regards to availability of WAVs (Wheelchair Accessible Vehicles)
at taxi ranks – members [wheelchair users] have told us that they
do not visit ranks as they do not expect a WAV to be available.  
• If WAV taxis were more regularly available at ranks, the preferred
means of hiring a licensed vehicle (by wheelchair users) would still
be by pre-booking, as most trips are not to or from a location near a
taxi rank. 
• Driver awareness of the needs of disabled passengers is generally ok
to good.  Some drivers forget on occasion that different people have
different needs.  Some awareness training is available to drivers.
• Occasionally taxis don’t turn up, or turn up late and due to this people
are missing NHS appointments.  As a consequence, travel is often
booked for an earlier time to allow more of a margin for late arrivals.
• Availability of taxis, especially WAVs tends to be the biggest issue in
recent times. People report that they are unable to book a WAV and
that they may get one to take them to a venue but cannot guarantee
they will be available to pick them up.  Which they've said can cause
anxiety or cause them not to book events in the first place. 
• Lack of taxi availability around school contract times remains an issue
for pre-booked hires.  This is especially difficult if a WAV vehicle is
required. 
• Often a taxi is the only method of public transport that some people
with mobility impairments can use, due to difficulties with other
methods or modes.  Indeed, in suburban and rural areas, this may
be the only option for people (both with and without disabilities) who
do not have access to a car.  Consequently, some people with
mobility impairments are more likely to require more frequent taxis
and for shorter journeys.  
• It is understood that some taxis and private hire cars which are
engaged on contract work for Perth and Kinross Council, do not also
undertake public facing hire work.  i.e. the drivers of some of the
vehicles which undertake contracts, such as school contracts, only
undertake these contracts and do not undertake any other form or
hire.
• Limited availability of licensed vehicles may be giving rise to lack of
competition for some Perth and Kinross Council contracts and hence
leading to inflationary pressures when pricing such contracts.  The
‘part time’ nature of these contracts suits some drivers and is more

Page 44

38 Perth Taxi Unmet Demand Survey
attractive than undertaking more numerous hires through booking
circuits or from ranks.
• Council transport contracts for locations in Perth and Kinross which
are outside Perth itself, are often fulfilled by Perth based operators
using Perth taxis, rather than taxis licensed to operate in other parts
of Perth & Kinross.
• A lot of users stick to the same company as they have had positive
experience with them 
Rail and other transport operators
In Perth, at the railway station, there were generally a small number of
taxis which arrived at the station in advance of arriving trains.  Rail staff at
the station had no view regarding availability of taxis.  They indicated that
there were generally taxis waiting for trains when they arrived and that
some people had booked a taxi in advance to meet them at the station
when a train arrived.
Stagecoach buses were contacted and indicated that there were no issues
with taxis.

6 Trade consultation
The BPG encourages all studies to include ‘all those involved in the trade’.
There are a number of different ways felt to be valid in meeting this
requirement, partly dependent on what the licensing authority feel is
reasonable and possible given the specifics of those involved in the trade in
their area.
A link to an online questionnaire was sent to members of the licensed
vehicle trades.  This included taxi operators and private hire car owners. 
A total of 78 responses to the online questionnaire were received. 
Not all respondents answer honestly.  Some respondents set out to provide
inputs that they believe will help to skew results towards an outcome which
they would prefer.  However, many other respondents to answer honestly. 
The data received was evaluated and those results which were intended to
skew results were identified.  For some of the analysis, these intentionally
erroneous results were excluded.
Of those 78 responses, 70 indicated that they were taxi drivers. 
Subsequent responses indicated that some of those who indicated that they
were taxi drivers, were in fact private hire car drivers and some were taxi
drivers from other areas within Perth & Kinross.  
All of the responses provided information of value.  However, some
responses which relate to Perth only matters were analysed on the basis of
responses from Perth drivers only.
What make and model of vehicle do you drive? e.g. Toyota Prius.
82% of drivers generally drove a saloon or estate car.  The remainder drove
MPV or Van based vehicles.
In terms of typical hours worked, the majority of Perth taxi drivers who
responded worked day time rather than night time hours.  
The maximum working hours per week claimed was 168 hours.  This is 24
hours per day 7 days per week.  Clearly, this level of continuous working is
not feasible.  
Respondents were also asked how many hires they undertook per day from
different sources; rank hires, pre-booked hires, contract hires and hailing. 
As with working hours, some respondents indicated either an excessive
number of hires or no hires.  These outlier results were excluded.
Once outlier data was excluded, the number of hires undertaken was plotted
against the number of hours worked.

Page 46

40 Perth Taxi Unmet Demand Survey 
Figure 8 - Plot of hires versus hours worked
The scatter graph of hires versus hours worked resulted in a trend line of
around 1.7 hires per hour.  
The type of work undertaken varied amongst respondents.  Some focussed
on contract work or airport runs.  Such work generally involves a lower
frequency of hires per hour worked.  Other drivers undertook a mix of pre-
booked hires and rank hires which can generate a higher number of hires
per hour.
Drivers were asked which type of hire best described the type of hire that
they most commonly undertook.  Responses indicated a mix of hire types. 
Around 25% primarily undertook contract or airport run type hires.  Around
46% of drivers predominantly undertook hires for immediate travel.  The
remainder of drivers were primarily engaged undertaking pre-booked hires.  
Respondents were asked how many hires each week required the carriage
of a wheelchair.  Around a third of taxi drivers indicated that they typically
carried one or more wheelchair using passenger per week.  Around half of
those who carried wheelchair passengers typically carried one or two
wheelchair passengers per week.  However, the remaining half of
respondents who carried wheelchair passengers indicated that they would
undertake several trips per week, carrying wheelchair users.  Around 7% of
drivers carried 15 or more wheelchair users per week.  The majority of
wheelchair user hires were obtained by pre-booking.
Drivers were asked if they had any regular clients who used a wheelchair
and any who had a mobility impairment.  The majority of Perth drivers, who
did not regularly carry wheelchairs also did not have any regular clients who

used wheelchairs.  However, some of these respondents did have regular
clients with mobility impairments.  
Of the Perth drivers who did regularly carry one or more wheelchair using
passengers, most had regular clients who used wheelchairs and regular
clients who had a mobility impairment.  Overall, around 50% of taxi drivers
had regular clients who had a mobility impairment.
Respondents were asked if the vehicle that they normally drove, was
normally driven by more than one driver.  35% of drivers indicated that
the vehicle they normally drove, was also driven by another driver. 
Respondents were asked if any existing ranks needed improvement. 
Responses included the following statements:
The railway station rank has special arrangements but I would like to have
access to it
Re-site the South Street rank opposite side of street, reinstate the other
South Street rank. Do away with the bus station rank. Open up the Scotrail
rank to all taxis and make a deal with Scotrail as it is a private rank and
you have to pay for the privilege to use it.
South street rank, needs to be moved back so the first taxi is facing Tesco
main door
An extra couple of spaces on each
Not enough spaces for taxis , South St rank needs to be moved so front of
rank is at Tesco’s door , to stop customers jumping in back taxi leaving taxi
at front of queue waiting
Needs to be more rank space for a start. 75 cars into 29 spaces does not
go. Drivers do not want to drive rank cars and prefer pre booked hires as
the anti social behaviour around ranks is terrible. Positioning and rank space
is something i was undertaken with licensing as chair of the taxi association.
Whilst they are sympathetic the block seems to be the PKC roads
department. Police and wardens need to manage the anti social behaviour
around the ranks by drug addicts , old people do not feel safe and prefer to
book by phone and be collected at a suitable place.
Murray Street......Improved safety for drivers perhaps stewarding at peak
times.

Do any new ranks need to be established?  If so, where should they
be located and why? 
There aren't many suitable places around town but I would assume that a
wee 3 car rank at the back of m&s would be beneficial 
Hospital  so people can come out and get one right away
possibly Bertha Park a small rank
Outside the loft nightclub, broxden park and ride,
Yes. As before, Broxden and scott street/kinoull st. 
By the concert hall 
In my personal opinion. I feel there should perhaps be a rank at
supermarkets, like Asda, Tesco etc. 
A rank beside the new Museum would be good, there are lots of
entertainment venues there
Broxden park n ride. Much more customers use this facility than bus station.
Bertha park. Covers a vast area on the outskirts with massive new housing
developments 
One at the retail park for shopers
The top of the hill at the front door of the PRI can be difficult to access and
there is no parking for taxis
Yes south st between south methven st and scott st
Railway station,  broxden bus station,  hospital
Outside Asda and both main Tesco's should be considered. There is
currently very poor drop off and collect facilities at all these sites
broxden park and ride, and perth royal infirmary
Broxden park and ride. New museum a drop off and pick up point. 
Proper drop off and pick up point Broxden Park and Ride beside the  bus
stops at the low level car park  otherwise cant think of anywhere else
Asda and crieff road tesco need rank 
A rank at George Street/ High Street would be useful as there is no rank in
that area for potential customers.

Are you aware of any times or locations where members of the
public may face difficulties hiring a taxi? 
There seems to be a short supply when the school runs are on.
Yes. Late weekends. Dont feel safe driving/on streets after dark anymore.
School contract time. At weekend night’s because the custom is not there
except at peak periods so not worth working
Not seen a lot of queues at mill street compared to years ago. This is
because people are booking their taxi home in advance to avoid walking to
the rank. Being picked up from a bar or restaurant for example
Morning rush hour. Taxis busy on school contracts.
SATURDAY 23.00-O100

Between 830-930 am due to contracts . Many private individuals have

1130 - 1am it can be busy but rest of night is quiet. If we put more cars on
we dilute the income and less drivers will work . It is a vicious circle.
8.30-09.30—14.30-15.30

Could you tell us how you feel licensed vehicle demand is likely to
change or develop over the next 12 months?  For example,
increased use of telephone bookings, fewer business trips etc.
Responses included the following representative statements:
More secure payment methods. Coping with roadworks (diversions) and
closures information
All round drop in trade. I cant see myself driving taxis in 12 months time
due to lack of income.
It’s not going to change unless PKC broaden their way of thinking. There is
nothing to entice people into the city centre. Do away with alcohol and unit
pricing and people will go out.
Seems to be much the same over the last few years and don’t see it
changing. If anything it is getting quieter and less busy due to the cost of

Page 52

46 Perth Taxi Unmet Demand Survey
living and the prices that bars and restaurants have to charge to survive.
Don’t see any change in business airport runs. Same people using taxis to
airports etc
Increased use of telephone and on-line bookings. Demand has stabilised
post COVID and expected to continue at the current level for the next 12
months.
Impossible to predict
More bookings
domestic trade within the city will continue to dwindle and long run agency
work will make it viable for drivers
Think younger people use apps for most things so be online bookings
More business runs
increase phone bookings 
the demand is likely to increase as Perth is rapidly growing and is used as
a centre point for business users and tourists alike, google plays a massive
part in this and for me telephone bookings and or internet bookings are
increasing, mainly due to the lack of taxis at key areas such as the railway
station and the park and ride
More telephone bookings
There are more houses being built and therefore more people. However,
there are changing habits in going out etc. We find a lot of people take
personal cars and do not drink. The public have changed a lot of habits due
to the bus services finishing earlier and we can often have a busier night on
a Monday or Tuesday if football is on TV than a weekend . Definite change
in habits of socialising.
More app bookings
More mobile
Wont change
Increased telephone bookings
More online bookings
Increase use of telephone bookings.
Few business trips less busy
More work coming in on telephone calls, the city is expanding but the
increase of taxis is static.

Page 53

47 Perth Taxi Unmet Demand Survey
Fewer business trips.
Mobile apps, increased population, improved road infrastructure
Increase in price and availability of public transport
With the cost of living going up and up, there could be a decrease in people
using taxis.
The trade is still trying to build up to pre covid levels ,customer base is
smaller as part of the covid and cost of living crisis, a few drivers got other
jobs during covid and still haven't been replaced
I will increase on all counts, the town is growing therefore the demand will
grow.
i think people more use telephone booking then rank
Economy & price increases
More people are using apps to book taxis and demand will increase
I personally think demand will continue to decrease across all forms of hire.
Perth town centre is no longer a place to meet or shop. The standard of
hotels does not encourage short breaks or any form of tourism. The general
public do not come in to town anymore due mostly to the lack of any quality
shops and the councils inability to move on beggars , drunks and those
under the influence of drugs
Less people going out into town, pubs quieter especially midweek. 
Is there anything else you would like to tell us about the licensed
vehicle trade?
There is a need for ongoing training for drivers, but achieving that without
disenfranchising drivers is very difficult.
The trade could probably do with a few more drivers, i think there’s plenty
licensed taxis in Perth, just not enough drivers to drive them all.
The issues I keep hearing from customers are cars being late or last minute
cancelled, unavailable for long times when needed asap, sometimes rude
dispatch or driver
The application process for school contracts should also be accessible to
small local businesses. The process itself is unclear, the website looks
outdated and is very unintuitive
Pay drivers a wage not self-employed

Page 54

48 Perth Taxi Unmet Demand Survey
We need to have more control on the way the cars are displaying private
hire badges on door panels
There only few yellow plates in this area and most of them owned by fewer
people it should be distributed among the driver whose always willing to
work that’s will help customers to get easy access to taxis
It would be nice if the licensing staff were out more at nights to check on
dress codes and conditions of the inside of some cars my daughter jumped
out of one from the rank as the car was stinking of cigarette smoke.  Also,
some private hire drivers doing food deliveries so the cars are stinking of
food.
More support given to drivers when complaints from the public received.
Most complaints are very one sided. 
Not well enough paid. Working for less than minimal wage.
Not enough enforcement. Dundee and Edinburgh cars picking up lots of
trade via uber app, carding while delivering parcels and poaching 
Yes still too many drivers not displaying their badge so passengers can’t
identify them 
There are currently a lot of taxis parked up, with some offices more than
29 taxis parked with no one to drive them. 
Need more hackneys...Private hire is saturated
Maybe open up yellow plates
There are more than enough cars but a lack of drivers. Policing is terrible
and this contributes to less people feeling safe in Perth late at night.
Youngsters seem to roam the town at all hours. More needs to be done to
protect drivers from taxi fraud and runners.  Police do not have the time or
resources and all too often nothing happens so drivers do not report this as
it will cost them more time and money. There is a definite fractured
relationship between licensing and the trade and this needs to be repaired 
All too often we hear about the wheelchair access trade but these customers
are very selective in their comments. They have no longer wait or
discrimination than other users , they simply do not book in advance ,
preferring to call on spec and having to wait 10-20 minutes .  We need more
drivers and we can get more cars driving. 
While not perfect, generally high level of efficiency and quality to meet
current and immediate future demands within Perth city and Perthshire 
As a private hire I am not allowed to take flag downs or sit on a rank.
Frequently I would be able to take fares if allowed.  After all yellow plates
Frequently steal our fares.

Page 55

49 Perth Taxi Unmet Demand Survey
Driver long hours to make a living. Dangerous !!!
Customers are usually supportive
People should stop abusing drivers 
Too many business people, outwith the taxi trade, own or are registered as
taxi plate operators and sub lease to actual drivers. 
Far too many scruffy taxi drivers 
An MOT every 3 months for a 7-10 year old vehicle is excessive 
The new museum has generated some additional fares - £4.20ish from the
station - and a driver would have to do 40 such runs a shift, if it were
possible, to get anywhere near minimum wage; 
It would help IF ALL yellow plated cars were actually out working.
Why are there so many "licensed" public hire vehicles parked up at peak
times. Time to open the trade up to cover demand.
There is a complete lack of wheelchair accessible taxis available , also there
are many taxis that are solely used for contract work or only work Monday
to Friday during the day as the operator is older and does not want to work
at any other time, there is an issue that because taxi licences have a
perceived value that many operators have several taxi licenses but don't
actually have those vehicles doing any rank based work
There’s plenty Hackney plates in use, but the majority are working in the
three main offices and being used as office cars hence the reason they are
not using the ranks
It can be a stressful job at times and to consider some way of increasing
taxis in Perth would put a lot more pressure on present Perth taxi drivers
and taxi businesses. 
Vehicles in poor condition and drivers not dressed appropriately 
As licence driver its very hard to make money now days specially after
covid. Thats why lots of driver left this professional 
And the final question, are there any other comments that you
would like to make?
Scrap the monopolies the major companies have. Create one company with
driver ownership and run it as a fair place to work. Perth is not big enough
to sustain the amount of taxis. Increase Hackney plates numbers and
reduce private hire, transfer contract only from excess private hire

Page 56

50 Perth Taxi Unmet Demand Survey
I personally think the Licensing board should do more spot checks on taxis
day and night cars to make sure cars are always being kept to a high
standard of cleanliness and tidiness.
I started a year ago and when I did the driver examination I thought it was
an unnecessary barrier to entry. Once I’d done it, I thought it was useful
training and I’ve continued to use what I learned.
Just tighten up on some drivers driving too many hours 1 guy I know is out
most mornings and is still out at 2-4 am the next morning it's shocking and
his level of driving is really worrying too.
Make owner operators work the taxi they own either day or night and not
just sit back and benefit by cashing in on having others working hard.  My
2 cars are out 5 days from 8 till 6. I go out from 7 till 10 others don’t even
do 1 hires rank work because of a massive contract.  All wrong and that’s
the issue.  Drivers don't want to work then hand 50% of the earning to
someone else.  I have 70 -30 split so they’re working for themselves.  Given
50% is not what self employed is about
To be paid the minimum hourly wage as basic income.
Plenty of taxis parked up as there are no drivers
The statistical questions in this survey are nonsensical, what were the
cameras for? Would they not provide the information you are looking for?
Until the trade can attract more drivers we will continue to struggle to
provide the service the public deserves, we have 3 taxis, 2 of which are
parked up at night, 7 nights a week. There are plenty of licenced vehicles
available but not enough competent drivers about to drive them.
Make it easier to buy plates
Poor driver standards
The sooner they remove the cap from taxi operator licenses the better as
you will then get owner operators who actually want to provide a service to
the general public, rather than those who pay the required fee and then
rent that license out at £150 per week
The last 5 plates you issued 4 are on minibuses and only do school
contracts, therefore are unavailable for rank work.
More ranks- not nearly enough
More drivers means more cars will be working
Easier application process
Driver Testing Abolished in favour of interview with licensing staff

Page 57

51 Perth Taxi Unmet Demand Survey
More spot checks on driver appearance and cars checked at random
Reintroduce annual testing of cars - new system too cumbersome and
impractical
Licensing department to be easier to contact or speak to
Promote the trade more positively- we have canvassed for a long time for
WAV only ranks and this should be promoted by the city and council as a
benefit to visitors
Need a union
Scrap the knowledge test to attract new driver
Taxis picking fares on rank in any position on the rank rather than FIRST
TAXI , this can cause friction among drivers and effects drivers that may
have been waiting quite a long time for a hire.
Private hire picking up off street
Private hire taxis are picking up from the streets
There has to be better control of the way cars get licences and I think there
should be follow up inspections for all cars
It's not lack of taxis , it's lack of drivers to drive that is the issue. So more
taxis would not solve any issues.
I would like to see more access to P&K team at High Street, very hard to
get a hold of
There should be a limit to hours taxi drivers work as seen some working
double shifts
Edinburgh plated cars are driving about Perth looking for work and the
licensing board don’t seem to stop them and ask why they are in Perth
Support the drivers in your city and encourage new drivers.
I feel that it is a difficult balance between too many taxis at quieter times
and not enough during busy times. I am a private operator and have been
driving on my own since covid and cannot get another driver to share due
to rank cars being available (Thursday, Friday, Saturday nights).

7 Evaluation of unmet demand and its significance
It is first important to define our specific view about what constitutes unmet
demand. Our definition is when a person turns up at a Taxi rank and finds
there is no vehicle there available for immediate hire. This can lead to a
queue of people building up, some of whom may walk off, whilst others will
wait until a vehicle collects them. 
There are other instances where a queue of passengers can be observed at
a Taxi rank, whilst a queue of Taxis is present, waiting to pick up
passengers. This can occur when the level of demand is such that it takes
longer for vehicles to move up to waiting passengers than passengers can
board and move away. This often occurs at railway stations, but can also
occur at other ranks where high levels of passenger arrivals occur. We do
not consider this is unmet demand, but geometric delay and although we
note this, it is not counted towards unmet demand being significant.
The industry standard index of the significance of unmet demand (ISUD)
was initiated at the time of the introduction of section 16 of the 1985
Transport Act as a numeric and consistent way of evaluating unmet demand
and its significance. The ISUD methodology was initially developed by a
university and subsequently adopted by consultants undertaking the
surveys made necessary to enable authorities to retain their limit on Taxi
vehicle numbers. The index has been developed over time to take into
account various court challenges. It has now become accepted as the
industry standard test of if identified unmet demand is significant. 
The index is a statistical guide derived to evaluate if observed unmet
demand is in fact significant. However, its basis is that early tests using first
principles identified based on a moderate sample suggested that the level
of index of 80 was the cut-off above which the index was in fact significant,
and that unmet demand therefore was such that action was needed in terms
of additional issue of plates to reduce the demand below this level, or a
complete change of policy if it was felt appropriate. This level has been
accepted as part of the industry standard. However, the index is not a strict
determinant and care is needed in providing the input samples as well as
interpreting the result provided. However, the index has various
components which can also be used to understand what is happening in the
rank-based and overall licensed vehicle market.
ISUD draws from several different parts of the study data. Each separate
component of the index is designed to capture a part of the operation of
the demand for Taxis and reflect this numerically. Whilst the principal inputs
are from the rank surveys, the measure of latent demand comes from the
public on-street surveys, and any final decision about if identified unmet
demand is significant, or in fact about the value of continuing the current
policy of restricting vehicle numbers, must be taken fully in the context of
a careful balance of all the evidence gathered during the survey process.

Page 59

53 Perth Taxi Unmet Demand Survey
The present ISUD calculation has two components which both could be zero.
In the case that either are zero, the overall index result is zero, which
means they clearly demonstrate there is no unmet demand which is
significant, even if other values are high.
The first component which can be zero is the proportion of daytime hours
where people are observed to have to wait for a Taxi to arrive. The level of
wait used is ANY average wait at all within any hour. The industry definition
of these hours varies, the main index user counts from 10:00 to 18:00 (i.e.
eight hours ending at 17:59). The present index is clear that unmet demand
cannot be significant if there are no such hours. The only rider on this
component is that the sample of hours collected must include a fair element
of such hours, and that if the value is non-zero, review of the potential
effect of a wider sample needs to be considered.
The other component which could be zero is the test identifying the
proportion of passengers which are travelling in any hour when the average
passenger wait in that hour is greater than one minute. 
If both of these components are non-zero, then the remaining components
of the index come into play. These are the peakiness factor, the seasonality
factor, average passenger delay, and the latent demand factor. 
Average passenger delay is the total amount of time waited by all
passengers in the sample, divided by the total number of passengers
observed who entered Taxis. 
The seasonality factor allows for the undertaking of rank survey work in
periods which are not typical, although guidance is that such periods should
normally be avoided if possible particularly as the impact of seasons may
not just be on the level of passenger demand, but may also impact on the
level of supply. This is particularly true in regard to if surveys are
undertaken when schools are active or not. 
Periods when schools are not active can lead to more Taxi vehicles being
available whilst they are not required for school contract work. Such periods
can also reduce Taxi demand with people away on holiday from the area.
Generally, use of Taxis is higher in December in the run-up to Christmas,
but much lower in January, February and the parts of July and August when
more people are likely to be on holiday. The factor tends to range from 0.8
for December to 1.2 for January / February. 
There can be special cases where summer demand needs to be covered,
although high peaks for tourist traffic use of Taxis tend not to be so
dominant at the current time, apart from in a few key tourist authorities.
The peakiness factor is generally either 1 (level demand generally) or 0.5
(demand has a high peak at one point during the week). This is used to
allow for the difficulty of any transport system being able to meet high levels

Page 60

54 Perth Taxi Unmet Demand Survey
of peaking. It is rarely possible or practicable for example for any public
transport system, or any road capacity, to be provided to cover a few peak
hours a week. 
The latent demand factor was added following a court case. It comes from
asking people in the public consultation questionnaires if they have ever
given up waiting for a Taxi at a rank in any part of the area, together with
any observation of passengers who had waited at a rank, then given up
waiting before a taxi arrived.  This factor generally only affects the level of
the index as it only ranges from 1.0 (no-one has given up) to 2.0 (everyone
says they have). It is also important to check that people are quoting
legitimate Taxi rank waits as some, for example, despite careful
questioning, quote giving up waiting at home, which must be for a pre-
booked hire, as there are few private homes with taxi ranks outside.
The ISUD index is the result of multiplying each of the components together
and benchmarking this against the cut-off value of 80. Changes in the
individual components of the index can also be illustrative. For example,
the growth of daytime hour queueing can be an earlier sign of unmet
demand developing than might be apparent from the proportion of people
experiencing a queue particularly as the former element is based on any
wait and not just that averaging over a minute. The change to a peaky
demand profile can tend towards reducing the potential for unmet demand
to be significant. 
Finally, any ISUD value must be interpreted in the light of the sample used
to feed it, as well as completely in the context of all other information
gathered. Generally, the guide of the index will tend not to be overturned
in regard to significant unmet demand being identified, but this cannot be
assumed to be the case – the index is a guide and a part of the evidence. 
ISUD value, Perth
For the 2024 survey, average passenger delay was 1.23 minutes (1 minute
14 seconds), this compares with the 2021 survey, when the average
passenger delay was 2.17 minutes (2 minutes 10 seconds). 
Periods when passengers had to wait for a taxi to arrive at the rank
amounted to 25.3% of weekday off peak hours.  This compares with the
2017 survey result, which was 16.9% of the observed off peaks hours.
40 % of passengers travelled in hours when there was an average wait of
over a minute. 
The demand profile did not exhibit highly peaked demand, resulting in a
factor of 1.0 being used. 
The seasonal factor is 1.0.

Page 61

55 Perth Taxi Unmet Demand Survey
The latent demand factor was 1.722  
The resultant ISUD value of 2,143.5 is significantly greater than the value
of 80 that would suggest the observed unmet demand might be significant. 
Consequently, this suggests that there is significant unmet demand.  
The result indicates that there are not sufficient taxis available at the taxi
ranks or by hailing, to satisfy demand and avoid the need for intending
passengers to wait for extended periods to hire a taxi at a rank of by hailing.

Railway Statistics 
Some demand for licensed vehicles is related to rail passenger volumes. 
Where rail passenger volume changes, we would expect to observe some
related change in associated use of licensed vehicles by rail passengers.

8 Summary and study conclusions
Level of unmet demand 
The ISUD index should not be taken in isolation as definitive evidence of
the level of unmet demand.  
The high index value does indeed suggest that the level of unmet demand
is significant.  This indicator was strongly corroborated by feedback from
the public and from stakeholders.  
If passenger waiting were limited to periods of peak demand, such as on
Friday and Saturday nights, then the coefficient in the ISUD calculation
which related to passenger queuing during off peak weekday periods, would
have been significantly lower.  However, passenger waiting was in evidence
during weekday off peak periods as well as during peak periods.  This
extended profile of passenger waiting also suggests an undersupply of taxis
over extended period, rather than focussed on peak periods.
The profile of rank usage, reflected in the profile of taxis leaving the ranks
with passengers, is relatively flat during Friday and Saturday nights. 
However, passenger waiting increased during the traditional peak periods. 
The passenger waiting peak suggests that there were peaks in demand
during Friday and Saturday nights, however, the level of supply did not rise
to meet that demand.
The evidence from different sources does corroborate the result of the ISUD
calculation, leading to the conclusion that the level of unmet demand for
taxis is significant.
Evaluation of results
The level of provision of taxi services at taxi ranks is dependent on several
key factors.  These are:
• The number of taxis licensed.
• The number of drivers who are driving the taxi vehicles.
• The times that drivers are working
• The type of hires which taxis/drivers are fulfilling
There are scenarios where the level of taxi availability at ranks could
increase, with no increase in the number of taxis which are licensed. 
Similarly, there are scenarios where the level of taxi availability at ranks
may not increase, even with an increase in the number of taxis licensed.
Feedback from public consultation indicated the view from some members
of the public, that the Council have direct input and control over how taxis
are operated.  This is not the case.  Whilst the Council may grant a right for
specific vehicles to operate as taxis and may grant the right for specific

Page 65

59 Perth Taxi Unmet Demand Survey
people to drive taxis, there is no control over when the taxis would be
operated or indeed the type of hires which would be undertaken by taxis.
In most of Perth & Kinross, the number of taxis licensed to operate is not
limited.  The operation of taxis in Perth & Kinross, outside Perth itself, is
subject to market forces and access to the market is unrestricted, subject
to applicants meeting licensing conditions.  
Within Perth itself, there is a cap on the number of taxis which are licensed. 
The implementation of a cap on the number of taxi licences issued, if often
held to be of benefit to the travelling public, as it ensures that the level of
provision is not excessive during off peak period and that driver earnings
would be of a sufficient level to encourage longer service in the trade.  Such
traits are expected, in turn, to lead to greater levels of experience and
professionalism and higher levels of service than may otherwise be
expected.
When we compare the results of the last unmet demand survey, prior to
the Covid-19 epidemic (in 2017), with the latest 2024 survey, we can see
that the volume of taxi hires obtained from the ranks in Perth was lower in
2024 than it was in 2017.  
Passenger waiting observed in 2024 was significantly greater than
passenger waiting observed in 2017.
Despite these contrary indicators, the number of taxis licensed in Perth has
increased since 2017.  
The traditional approach to addressing levels of unmet demand for taxis
which is significant, is to issue more taxi licences.  However, there are more
licences in operation in 2024 than there were in 2017 and despite lower
levels of rank based hires observed in 2024, the level of unmet demand is
higher in 2024.  
There was a high level of suppressed or latent demand indicated in the
feedback from the public.  i.e. if there were more taxis readily available at
the ranks, more people would use the taxis to be found at the ranks.
The majority of licensed vehicle hires undertaken by the public are booked
hires, rather than hires obtained at taxi ranks.  Feedback from the trade
indicates that most taxi hires are obtained through pre-booking rather than
from ranks.  The level of hires obtained from pre-booking appears to have
increased since before the Covid-19 pandemic.  
It seems plausible that changes in operating practices amongst the trade,
coupled with changes in patterns of demand, have both influenced the level
of availability of taxis at ranks.  Whilst taxis are engaged on pre-booked
hires, they are less likely to visit ranks.  This is especially likely during busy
periods when they may be engaged in a sequence of back-to-back pre-
booked hires, without the opportunity to visit the ranks between hires.

Page 66

60 Perth Taxi Unmet Demand Survey
As more taxis engaged in pre-booked hires in recent years, passengers used
this facility more readily.  
Some of the feedback from public consultation included comments from
people stating that they had to book a licensed vehicle by phone or app,
because there were no taxis operating from the ranks, because many of the
taxis were fulfilling these pre-booked hires.  The implication from some of
these comments was that the respondents would prefer to just go to a rank
rather than have to book a taxi.  However, this preference may be related
to an expectation that booking a taxi involves a wait for the taxi to arrive,
whilst if there were taxis waiting at a rank, there would be less waiting time. 
Consequently, if bookings were fulfilled within a short time period (less than
5 minutes) passengers may be less willing to walk to a rank rather than
pre-book a taxi.
The feedback from the public indicated that under supply of licensed
vehicles was an issue with pre-booked hire of licensed vehicles, for
immediate hire, as well as an issue with taxi availability at ranks.  If there
was a significant increase in licensed vehicles available to pre-book, it is
likely that this increase in capacity would fulfil some of the unmet demand
for taxis at the taxi ranks.  
It is tempting to assume that all the taxis in the fleet are primarily engaged
in public facing hire work, either from taxi ranks or through pre-booked
hires.  However, there is some plausible evidence that some taxis are
normally engaged in undertaking contract hires and do not supplement this
work with public facing hire work.  
There is some suggestion from the trade that some taxis are not in regular
operation.  This suggestion is based on a case that these taxis are rented
to drivers and fares are split with the taxi owner and that there are
insufficient drivers available and willing to pay the rent for the taxis.  It was
not possible to verify this situation.  However, if true, this would be a
plausible contribution to the lack of supply at taxi ranks, despite the
increase in licensed taxis in recent years.
The purpose of this survey is to identify whether there is sufficient
availability of taxis at the ranks to meet the level of demand.  
The result of the survey is a clear indication that there is not sufficient
availability of taxis at the taxi ranks, to meet demand.
The number of hires obtained from ranks has fallen dramatically since 2017. 
The hires observed at ranks in 2024 were around 48% of the level observed
in 2017.  The number of taxis in the fleet has increased by 6.7%.  Despite
more taxis and less hires taking place at ranks, the number of people who
had to wait for taxis to arrive at the ranks had increased by 108%.

Page 67

61 Perth Taxi Unmet Demand Survey
Clearly, the way in which taxis operate has changed.  The way in which
people hire licensed vehicles has also changed, with more people pre-
booking hires for immediate travel.
The situation in 2024, compared with 2017, was that use of the ranks has
reduced, passenger waiting has increased and the number of taxis in the
fleet has increased, but the increase has not addressed the increased
passenger waiting and hence the level of unmet demand is significant.
Consideration of potential measures
Perth & Kinross Council need to consider potential measures to address the
lack of availability of taxis at ranks.  However, the range of potential
measures which could be applied is relatively limited.
Measures could include actions and initiatives to encourage some of the
following outcomes:
• Increase the number of taxis which are licensed
• Increase the number of taxis which operate from the ranks
• Change the mix of pre-booked hires and rank based hires, in favour
of rank operation.
• Increase the number of drivers who drive taxis and attend ranks.
• Increase the number of hours each week when existing taxis are
operating, through measures such as multi-shift usage, or
encouraging part-time drivers to work full time.
If more taxi licences are issued in the future, it would be highly unlikely that
all of these taxis would operate from the ranks.  
If three additional taxis were to work from the ranks on Friday and Saturday
nights and one additional taxi were to operate from the ranks during
weekdays and weekend day times, this would provide sufficient additional
capacity to reduce the level of unmet demand to a level which is not
significant.  However, this assessment assumes that the level of demand
from passengers at the ranks would not increase, as a result of increased
availability.   
It is highly unlikely that if four additional licences were issued, they would
be operated as taxis which worked solely from the ranks.  
It is also unlikely that demand levels would remain static, if provision at the
ranks were to be increased.
In order to provide an equivalent of three additional taxis during night time
peaks, we need to consider how this could be achieved.  As operational
practices vary regarding how taxis obtain hires, we would need to scale
provision to achieve the equivalent of three extra taxis working from the
ranks on Friday and Saturday nights.

Page 68

62 Perth Taxi Unmet Demand Survey
We need to consider how to scale the fleet size, in order that the observed
equivalent number of taxis operating from the ranks on Friday and Saturday
night, were to increase by 3.
Evaluation of the rank activity indicated that on Friday and Saturday nights,
around 8 taxis on Friday and 10 taxis on Saturday were operating from the
ranks.  These are equivalences calculated from observed data.  In reality,
there were more taxis operating on Friday and Saturday nights during the
rank surveys.  However, some of those taxis which attended the ranks also
undertook pre-booked hires and so were only in attendance at the ranks
part time.  Hence, the level of provision on Friday and Saturday nights was
equivalent to 8 taxis on Friday and 10 taxis on Saturday working solely from
the ranks and not undertaking other types of hires.
An increase of three taxis (equivalent) on Saturday night would require a
30% increase in provision, if it were assumed that taxis (including those
newly licensed) would continue to be operated in the same way as they
were during the rank surveys.  i.e. some taxis focussing on pre-booked
hires, some on a mix of pre-booked and rank based hires and some focusing
on contract hires and perhaps some not working at all but waiting, ready
for new drivers to work the taxis on a rental and shared fares basis. 
Therefore, we would need to increase the size of the taxi fleet by 30% in
order that the mix of operational practices could result in a 30% increase
in provision at the ranks.
If we were to increase the taxi fleet by 30% this would be an increase of 24
licences.  
If 24 licences were to be made available, the take up of some of the licences
would be by existing drivers of private hire cars and existing taxi drivers,
who don’t own their own taxi.  As such, unless more drivers could be
recruited by the owners of the vehicles previously driven by these drivers,
the transfer of existing drivers would reduce the net gain in provision and
hence capacity at ranks.
If 24 licences were issued and taken up, it is likely that some of the licences
would be taken up by people who previously operated private hire cars.  As
such, if private hire cars were re-plated with a taxi plates, there may be no
net gain in capacity with those specific plates, if the taxis then continued to
fulfil the pre-booked hires that the vehicles previously fulfilled as private
hire cars.
If the licence cap were increased by 24 in a single move, it may be that not
all licences are initially taken up.  In such a situation, it may be considered
that the difference between having a cap level above the number of licences
issued is no different to removing the cap altogether.  However, there may
be some practical differences in terms of how people view existing licences
against a potential new licence.

Page 69

63 Perth Taxi Unmet Demand Survey
Trade feedback indicated that there is a perceived notional value in holding
a taxi licence and a business, including the taxi licence can be sold.  The
value of the business to be transferred would include a ‘plate value’
premium.  If the licence cap were removed and no vehicle conditions applied
to any new licences, the plate value of existing plates would be likely to be
reduced to zero.  This may discourage operators from retaining licenced
taxis which are not in regular use.  
An alternative scenario could be that the cap on licences were removed, but
vehicle conditions applied to any new licences, that they would need to be
for wheelchair accessible taxis.  In such a scenario, existing plates which
retained ‘grandfather rights’ to be operated without the need to be
wheelchair accessible, would retain a value.  However, such a value would
be contingent on whether these grandfather rights could be transferred,
with the sale of the business and transfer of the licence.  
A further alternative scenario could be that the cap on licences were
removed and any new licences or transferred licences would need to be
wheelchair accessible vehicles.  In this scenario, existing licence holders (of
licences which did not require operation of wheelchair accessible vehicles)
could continue to operate as such, so long as the licence holder continued
to operate the licence.  Under this scenario, licences owned by individual
owner / drivers would eventually be transferred once the owner retired from
the trade.  Then the licence would need to operate a wheelchair accessible
vehicle.  However, if a licence were registered with a company, then
potentially, ‘ownership’ of the licence could be transferred with the
company, without the need to transfer to a new licence holder.  Such
licences could potentially continue in perpetuity to exercise grandfather
rights to operate non-wheelchair accessible vehicles.
Wheelchair accessible vehicles are more expensive to own and operate than
saloon cars and hence, operation of a cheaper saloon car taxi is a
preferrable option for some operators, as taxi fares are fixed, irrespective
of the size and cost of the vehicle used.
For various reasons, the level of use of taxi ranks to hire taxis has fallen
since 2017.  If the number of taxis were to be increased by 30% to cater
for this lower level of usage, there would inevitably be an impact on other
aspects of the licensed vehicle trade in Perth.
The type of existing taxi ownership will also influence the effectiveness of
introducing additional taxi licences.  For example, companies which own
multiple vehicles and rent these to drivers, may find some difficulty in
recruiting new drivers, if some of the existing drivers take up a new licence. 
Alternatively, renting a taxi provides a means of access to the trade for
people who do not have the capital to invest in a vehicle, so if some or all
newly introduced licences were taken up by existing fleets, this could

Page 70

64 Perth Taxi Unmet Demand Survey
provide an avenue for more drivers to join the trade with low levels of
investment.
In reality, the introduction of such a large increase in taxi licences would
have an impact on the trade which would be difficult to predict.
If the introduction of a large number of licences is considered, it is also
worth considering whether there is a realistic difference between a large
release of licences or removing the cap altogether.
Disabled users and the need for wheelchair accessible taxis
Whilst the public in general has faced difficulty in reliably obtaining licensed
vehicle services, disabled users and in particular wheelchair users continue
to face increased difficulties, over and above those faced by non-disabled
passengers.  Increased availability of wheelchair accessible taxis and
private hire cars has been called for by the public.  One measure which can
increase wheelchair accessible vehicle provision, is to have a requirement
that any additional licences should be for wheelchair accessible vehicles
only.
The cost of purchasing or leasing and subsequently operating a wheelchair
accessible vehicle can be significantly higher than the equivalent costs for
operating a saloon car as a taxi.  Therefore, a wheelchair accessible vehicle
condition for any new licences may discourage some potential applicants.
Most journeys in a wheelchair accessible licensed vehicle are pre-booked. 
Rank based hires of wheelchair accessible taxis are relatively rare.  A
common issue with obtaining the service of wheelchair accessible taxis, in
some locations, is that few of the taxis are directly contactable by
wheelchair users, in order to book travel.  In Perth, this is likely to be less
of an issue as many of the existing taxis obtain pre-booked hires, through
a booking office, app based system, or directly by telephone or messaging
contact between passengers and drivers. 
Feedback from stakeholders and trade members indicates that some of the
wheelchair accessible taxis most recently licensed in Perth are
predominantly or solely engaged in contract hire work and don’t provide
any service at taxi ranks.  Potentially, some additional licences issued could
be deployed in the same way.
If we consider measures which may:
• Change the mix of pre-booked hires and rank based hires, in favour
of rank operation.
• Increase the number of drivers who drive taxis and attend ranks.
• Increase the number of hours each week when existing taxis are
operating, through measures such as multi-shift usage, or
encouraging part-time drivers to work full time.

Page 71

65 Perth Taxi Unmet Demand Survey
The only realistically feasible measure which may result in the outcomes
above, would be to increase the driver’s income.  In turn, this is likely to be
achievable only by considering changes to the fares tariff.  Taxi fares are
outside the scope of this survey and are not considered further.
In order to increase the number of taxis which attend ranks, if driver
operational patterns are not changed, then more taxi vehicle licences would
need to be issued.  It would be assumed that some of these additional
licences would operate for at least some of the time, from ranks and that
some new licences would attract new drivers into the trade, either directly
or indirectly.
If more licences are to be issued, the question of how many and whether
they should be required to be wheelchair accessible taxis should be
considered.
Some of the most recently issued licences are required to operate
wheelchair accessible taxis.  Therefore, if a significant number of new
licences were issued, which did not have this requirement, then existing
holders of the newest licences may feel aggrieved.  Some holders of
wheelchair accessible vehicle licences could apply for a new un-restricted
licence and hand in an existing licence with a wheelchair accessible vehicle
requirement.  Realistically, any additional licences would probably need to
be issued with a condition that vehicles require to be approved wheelchair
accessible vehicles.
There is an option of making no changes and letting market forces deal with
demand for licensed vehicles.  
In such a scenario, it would be anticipated that, over time, more private
hire cars would be licensed to deal with the excess level of demand for pre-
booked hires.  
If the size of the private hire fleet were to increase, more travellers would
book travel rather than go to taxi ranks.  The resulting increase in private
hire cars may drive more of the taxi fleet back to the ranks, owing to
increased competition for pre-booked hires.
At present, there is no realistically feasible method of predicting how long
it would take for private hire numbers to increase sufficiently.
An alternative to increasing the cap in licence numbers would be to remove
the cap altogether.  The results are likely to be similar to retaining the cap
with a large increase.  However, if the cap is removed, it can be difficult to
re-introduce a cap in the future if it is felt that a new cap is required.

9 Recommendations
On the basis of the evidence gathered, our key conclusion is that there was
evidence that there was unmet demand for the services of Taxis, which was
above the level which is significant.  It is prudent to consider measures to
be implemented.  
In order to address unmet demand and increase the level of availability of
taxis, the only measures open to the licensing authority (The Council) are
to consider increasing the number of taxis licensed in Perth.  
In order to comply with existing policy, it is likely that any additional taxis
licensed, would be wheelchair accessible taxis.  
The level of observed passenger waiting was relatively high.  The number
of additional taxis required to address unmet demand would equate to a
significant increase in the fleet size.  
If no changes to operational patterns were made as a result of increasing
the number of licences then 24 additional licences would be required.  
Owing to the uncertainty of how newly licensed taxis would be operated, it
is prudent to consider a range of potential additional licences to be issued. 
This would offer the flexibility to introduce the lower end of the range
initially and, if these additional licences did not lead to a notable reduction
in passenger waiting, then an additional phase of licence release could be
implemented.
It is recommended that the issue of an additional 24 licences, over
and above those already in circulation, is considered at this time,
with the option to release licences in phases.

This document is intended to be read in conjunction with the Perth Taxi
Unmet Demand Survey 2024 report, prepared by LVSA.  This is referred to
as ‘the report’.
The addendum is intended to correct errors in the original report and to
present some additional information which may help to further explain some
of the report contents and recommendations.

On page 6 of the report, fares are compared with other authority areas in
Scotland.  The report states that “fares in Perth & Kinross were ranked 291
our to 362 authorities listed.”  This should be corrected to ‘fares in Perth &
Kinross were ranked 205 out of 341 authorities’.

Perth Taxi Unmet Demand Survey 
3 Perth Railway Station
The taxi rank at Perth Railway Station lies within the curtilage of railway
property.  In common with many such railway station ranks around the
country, any taxis which wish to service this rank require an additional
permit to wait on the rank for passengers.  There is an annual cost payable
to hold such a permit.  
It is the view of LVSA that all locations where taxis commonly wait for fares,
including formal ranks, informal ranks and ranks on private grounds, should
be included in an unmet demand the assessment.  Taxis which wait at
informal locations and private ranks are not available at other locations,
including public ranks.  
The assessment in the report did include the private rank at the railway
station.  In order to gauge the degree to which the inlusion of the rank at
the railway station influenced the result, we have undertaken a further
calculation of the Index of Significance of Unmet Demand (ISUD) value.
The ISUD index is a value which increases exponentially with increased
occurrence of passenger waiting.  The index is influenced by when
passenger waiting occurs.  Off peak passenger waiting has greater influence
than peak period passenger waiting.
The ISUD value, including the Railway Station rank was 2,143.5.  When the
observations at the Railway Station were excluded, the value dropped to
1,614.9. 
Both values are well in excess of the threshold value of 80, which suggests
that the level of unmet demand was significant.

The comparison confirms that there are not sufficient taxis available at
public ranks to meet the needs of intending passengers and to ensure that
unmet demand is below a level which is significant.
