1 INTRODUCTION
1.1 Go-surveys limited have been commissioned by Lidl UK GmbH to provide traffic and transport
advice in support of their planning application for the redevelopment of their existing store at
Colchester Avenue, Cardiff.
1.2 It is proposed to redevelop and rationalise the existing site which has a Gross Internal Area
(GIA) of 1,444m2 to accommodate a store with a GIA of 2,548m2 and associated car parking
and servicing facilities. As part of the development proposals the adjoining site (that was
formally occupied by a ‘HSS’ tool and equipment hire retail/commercial outlet), which has a GIA
of 1,282m2, has been acquired by Lidl and will be incorporated into the development proposals.
1.3 The redevelopment proposals will see the position of the store largely unchanged from its
existing north-easterly position within the site. The main purpose of the proposals are to update
and improve warehousing and operational functions within the store to ensure that these are in
line with Lidl’s latest build specification, with a key aim to improve the experience of both
existing and new customers within the store
1.4 The existing store is considered a 'first generation' of Lidl stores and as such it now struggles to
meet Lidl’s high servicing and operational requirements. In short, the new store needs to be
'future proofed' to achieve Lidl’s expectations and those of their customers, ensuring that they
produce the best possible shopping experience in store, whilst providing a first rate place of
employment for their staff. Whilst the primary aim of these improvements are intended to
benefit existing customers, it is acknowledged that the proposals may result in some new
customer volume, albeit by a relatively small amount.
1.5 This Transport Assessment has been prepared to assess:
• the trip attraction comparison between the existing store and former ‘HSS’ site (that was
operational at the time of the traffic surveys and which will be encompassed within the
development proposals) and the proposed store, to show that there will be a nil detriment
impact on the adjoining local highway network; and
• the suitability of the parking provision within the site as a result of the redevelopment
proposals; and
• the internal access and servicing arrangements.

1.6 The scope of this report has been agreed discussed with the highways officer within Cardiff
Council (CC).
1.7 This report has been produced in accordance with the Welsh Government Technical Advice
Note 18: Transport (March, 2007).
1.8 The structure of the report is as follows:
• Section 2: sets out the existing conditions;
• Section 3: details the redevelopment proposals
• Section 4: forecasts the vehicular trip attraction to the site and provides comment on the
effect on the:
§ adjacent highway;
§ the utilisation of the car park;
§ the proposed servicing arrangements; and
• Section 5: Provides a summary and conclusions.

2 EXISTING CONDITIONS
Site Details
2.1 The site is located to the north east of Cardiff in Roath. The location of the site is shown in
Figure 1. The site comprises an area of 3,966m2, and includes an existing Lidl food store with
a GIA of 1,444m2, of which 1,134m2 classified as Sales Area.
Figure 1: Site Location Plan
2.2 The site is surrounded to the north, east and west by a number of retail/commercial properties
and to the south by Colchester Avenue. The site lies to the west of A4161 Newport Road, which
provides access to a large number of retail/commercial/leisure units.
2.3 The site is currently occupied by a well established Lidl store that is ideally located to meet the
convenience shopping needs in this part of Cardiff. The store caters mainly for food and
convenience shopping needs; acting as a 'top-up' facility for the local catchment population
many of whom are within a convenient walking/cycling distance from the Store. There will also,

due to the location of the site, be a large element of pass-by trips and trips linked with visits to
the adjacent retail/commercial outlets.
Site Access
2.4 Vehicular access to the site is provided via a priority controlled ‘T’ junction which benefits from
the provision of ‘ghost island’ right turn facility and provides direct access to/from Colchester
Avenue. Pedestrian and cycle access to the site is provided via the footway adjacent to the
southern boundary of the site.
Accessibility by Public Transport
2.5 The site is served by a large number of bus services that directly pass the site on Colchester
Avenue, with bus stop(s) located adjacent to the site access. The site also benefits from being
within a short walking distance i.e. within 200m from a number of bus stops on Newport Road
providing frequent public transport links between the site and surrounding local communities.
Details of the bus services in the vicinity of the site are provided in Table 2.1.

facilities and real time service information displays. Full details of the bus routes serving the site
can be found at: www.cardiffbus.com and www.traveline.info.
Cyclist/Pedestrian Accessibility
2.7 One of the main factors demonstrating the suitability of a development site is its accessibility by
non-car modes of transport. This helps to reduce the reliance on the use of the private car as
well as promoting the aims of ‘smarter’ travel choices.
Proposed Redevelopmnet Lidl, Colchester Avenue, Cardiff– Transport Assessment 8 Macintosh HD:go-surveys:Transport Planning:GS334 - Lidl, Colchester Avenue, Cardiff - TA_TP:Word:GS334-2016 - Lidl, Colchester Avenue, Cardiff - Transport Assessment - Final.docx Aug 2016
2.8 It is reasonable to expect that the typical able bodied person is capable of walking at least 2km
for day to day activities. The thrust of sustainability policy is that there will be an increasing
propensity for people to use non single car occupancy modes, of which walking is one. People
will choose their mode based on their journey purpose, and it is reasonable to conclude that a
significant proportion of local residents will choose to walk to the site.
2.9 It is reasonable to expect that for a typical able bodied person a cycle distance of up to 5km is
readily achievable and attractive. The propensity for people to choose to cycle will depend on
journey purpose and individual ethos.
2.10 Figures 2 and 3 show the 2km and 5km walking/cycling catchment for the site respectively.

Figure 3 - 5km Walking/Cycling Isochrone
2.11 There are a number of existing footways that serve the site providing access to the local
residential catchment area. In addition, there are a number of formal (signalised crossings) and
informal pedestrian crossing points (dropped kerbs and tactile paving) along the junctions and
pedestrian desire lines in the vicinity of the site enhancing the provision for
customers/employees walking or cycling to the site. Street lighting is also present on both
Colchester Avenue and Newport Road further enhancing pedestrian safety.
2.12 On the Cardiff Cycling Map, Colchester Avenue is allocated as an advisory route for cyclists, that
links into the traffic free route adjacent to Newport Road. An extract from the Cardiff Cycling
Map is shown in Figure 4.

Accident Analysis
2.13 Personal Injury Collision (PIC) data has been obtained from ‘Crash Map’ for the road network
within the immediate vicinity of the existing site access and Colchester Avenue, between the
01/01/2010 and 31/12/14.
2.14 An examination of the PIC data indicates that there has been no PICs recorded over the 5-year
period reviewed. It is therefore considered that there is no highway safety issue associated with
the operation or layout of the existing site access.
Existing Trip Attraction
2.15 Details of the observed trip attraction for the Lidl store and ‘HSS site’ (that was still operational
at the time of the surveys) have been derived from Manual Classified Count (MCC) traffic
surveys undertaken at the access to the site on Friday 8th and Saturday 9th January 2016
between 08:00-22:00 during both days and correspond with the opening hours of the Lidl store
during each of these days.
2.16 The observed daily arrival and departure profiles for Friday and Saturday for the Lidl store are
shown in Figures 5 and 6 respectively.

2.19 An analysis of the existing Lidl traffic attraction has identified that the Friday and Saturday peak
periods are between 11:00 – 12:00 and 14:00 – 15:00 respectively.
2.20 It should be noted that during the highway network AM peak period (08:00-09:00) there were
observed to be 84 two way movements associated with the operation of the Lidl site which
equates to only 4% of the total daily movements to the site.

Car Parking
2.22 There are currently a total of 74 car parking spaces within the store car park, of which 3 (4%)
are designated for disabled use and 2 (3%) for parent & child use.
2.23 Car park accumulation surveys of the Lidl store were undertaken on Friday 8th and Saturday 9th
January 2016 between 08:00 – 22:00 in order to ascertain the existing parking utilisation for
the store. The analysis of the data has indicated that the maximum utilisation of the car park
occurs on a Saturday between 14:30-14:45 whereby the car park had a maximum occupancy of
89%. The results as shown in Figures 9 and 10 indicate that the car park is relatively well
used especially during a Saturday.

3 DEVELOPMENT PROPOSALS
3.1 The redevelopment proposals will see the footprint of the existing Lidl store increased and the
adjoining site formally occupied by the ‘HSS’ site incorporated into the development proposals
to accommodate the displaced/reconfigured parking within the site. The aim of this
redevelopment is to improve the retail offering and shopping environment for existing
customers and to improve the overall operation of the site.
3.2 A copy of the proposed site layout including parking arrangements is shown in Figure 11.
Figure 11 – Proposed Site layout.

Development Composition
3.3 The development proposals will increase the Gross Internal Area (GIA) of the Lidl store from
1,444m2 to 2,548m2. It should be noted however that the proposed redevelopment includes the
former ‘HSS’ site which has a GIA of 1,282 m2 of which 455m2 is classified as sales area,
therefore the proposals will result in an overall decrease in the GIA of the total existing site of
178m2 and a decrease in the overall sales area of the site by 165m2.
3.4 Through the development proposals, Lidl seek to enhance the quality of the store’s existing
retail offer, together with improvements to the parking layout.
Parking
3.5 The redevelopment proposals will result in an increase in the overall number of parking spaces
associated with the Lidl store from 74 to 91, which will include 6 (7%) spaces designated for
disabled use and 4 (5%) designated for parent & child use. The reconfiguration of the car park
will retain the disabled spaces and parent and child spaces adjacent to the store entrance
retaining the convenience customers who utilise these spaces.
3.6 Since no additional product lines will be introduced following the redevelopment, Lidl do not
anticipate a significant increase in customer numbers, thus concurring with the view that
increasing the size of the sales area of the store will not be reflected in a directly proportional
increase in customer volume and hence traffic attraction to the site. Primarily, the focus of the
proposals is to improve the retail offer to existing customers by providing a more pleasant
shopping environment and by providing improved storage and back room functionality, with this
later element comprising by far the majority of the proposed increase in GIA for the proposed
Lidl store.
3.7 Further details on the forecast car parking utilisation as a result of the development proposals
are provided in Section 4.
Vehicular Access
3.8 The existing site access from Colchester Avenue will be retained unchanged for the use of
customers and service vehicles. The site access arrangements are shown in Drawing Ref:
GS334-D-A01 – Rev 03.

3.9 Access to the former ‘HSS’ site will be stopped up therefore consolidating the number of access
points to the site, which will have the benefit of reducing the level of interaction at the site
access from that previously experienced.
Pedestrian/Cycling facilities
3.10 The existing Pedestrian and cycling facilities in the vicinity of the site are considered to be good.
The location of the site is extremely well placed in terms of accessibility and connects with the
existing pedestrian footways immediately adjacent to the site.
3.11 Long term (5 spaces) and short term (10 spaces) cycle parking will be provided on site for the
use of employees and customers in a safe, secure and convenient location within the car park in
close proximity to the store entrance of the site as shown in Drawing Ref: GS334-D-A01–
Rev 03.
Parking
3.12 The parking provision on the site will be broadly in accordance with Cardiff Councils parking
guidance (Jan 2010) as summarised in Table 3.1.
Table 3.1: Cardiff Council Maximum Parking Standards (Non Central Area)
3.13 Based on the relevant parking guidelines the proposed parking provision within the site is
detailed in Table 3.2 and shown in Figure 11.

Table 3.2: Proposed Parking Provision within the site.
Internal Highway Layout
3.14 The proposed internal site layout is shown in Figure 11 and has been designed to make the
most efficient use of the space whilst having regard to the safe access, circulation and parking
within the site.
Servicing
3.15 Servicing of the proposed site will be facilitated at the northeast corner of the store through the
use of a dedicated service bay. Drawing Ref: GS334-D-A01–Rev03 shows how the
proposed servicing arrangements can be accommodated within the site for the largest 16.5m
Articulated Vehicle anticipated for this type of development.
3.16 With regard to the servicing arrangements of the proposed the Lidl food store, Lidl as a multi-
national operator, have full control over their supply chain and have the infrastructure,
expertise and logistics network in place to allow efficient multi-platform operations and cross
docking of goods at nationwide centralised depots. For this reason, deliveries can be confined
to a minimal number and undertaken in an adept manner, so that all servicing is both efficient
and effective and can fully control all servicing requirements associated with their operation.
Under Lidl’s current servicing arrangements, Lidl food stores of this size typically receive 1
delivery per day or infrequently where peak periods in demand dictate otherwise (e.g.
Christmas period), a maximum of 2 deliveries per day, which are scheduled to arrive at different
times during the day i.e. 1 delivery in the morning and 1 delivery in the afternoon.
3.17 For these reasons, the provision of one dedicated service bay is considered more than sufficient
to meet the requirements of the forecast servicing arrangements of the site and corresponds
with the existing provision at the site and that of other Lidl stores throughout South Wales.

3.18 In the majority of instances, deliveries to the store will be undertaken during the off-peak
highway hours when traffic levels are relatively light. In other words, it is unlikely that deliveries
will be undertaken in the AM or PM peak hour.
3.19 Instead of the main depot delivery returning empty, on their return journey, Lidl vehicles
remove empty pallets, freezer boxes and recyclable material, thereby reducing the number of
servicing trips. This also reduces fuel usage, vehicle mileage and overall lowers servicing trips.

4 QUANTITATIVE ASSESSMENT
4.1 This section of the report quantifies the potential effect of the proposed redevelopment by
examining changes in traffic attraction and thus traffic impact.
Observed Lidl Trip Attraction
4.2 The existing traffic attraction at the store during a typical Friday and Saturday is summarised in
Section 3.
4.3 As previously noted, the development proposals for the store will result in a decrease in the
total GIA of the entirety of the buildings within the site from 2,726m2 to 2,548m2 and a decrease
in the total sales area of the site from 1,589m2 to 1,424m2.
4.4 By redeveloping the store, Lidl seek to enhance the quality of the store’s existing retail offer by
providing an improved shopping experience for customers and place of employment for staff.
4.5 The store improvements are being proposed in response to a change in build specification and
will offer a new shopping experience for those using the store. As such the major beneficiaries
of the proposals will be existing customers although, as this report will identify, it is anticipated
that some new customers will result from the proposals.
4.6 The redevelopment will allow for additional shelf space, enabling Lidl to keep greater quantities
of key lines on the shelves, thereby reducing the necessity for restocking during the stores
opening hours.
4.7 The proposals mirror similar schemes that Lidl are engaged in throughout their store portfolio
across the UK and these changes reflect a general trend towards the improvement of the
existing offering, and improved back room functionality.
Trip Attraction
Using TRICS
4.8 TRICS is a valued and respected database that is typically used to predict traffic generations for
new build developments based on data derived from comparable sites. However, it has two
significant weaknesses; much of the data is quite old and does not reflect modern retail
Proposed Redevelopmnet Lidl, Colchester Avenue, Cardiff– Transport Assessment 23 Macintosh HD:go-surveys:Transport Planning:GS334 - Lidl, Colchester Avenue, Cardiff - TA_TP:Word:GS334-2016 - Lidl, Colchester Avenue, Cardiff - Transport Assessment - Final.docx Aug 2016
formats; and little if any useful data exists to indicate the incremental effect of extending a food
retail store.
4.9 Therefore, the use of TRICS data is not appropriate for this purpose as the development is not
a ‘new’ development but the redevelopment of an existing store.
4.10 There is an existing demand for the store which will continue to be served by the store once the
redevelopment is complete. At the same time, the proposed increase in sales area is primarily
focused on improving the offer to existing customers rather than significantly increasing trade
draw or catchment of the store.
4.11 On this basis, it is considered that the appropriate starting point for determining the additional
trip generation associated with the redevelopment should be by the use of the observed traffic
data from Lidl and not hypothetical trip rates from TRICS. As has already been stated, TRICS
has little data that would allow the effect of an redevelopment to be quantified. Instead, it
would be necessary using TRICS to treat the extended store as a new entity, which is clearly
not the case.
Using Observed Lidl Data
4.12 Although the development proposals will result in a decrease in the total GIA of the site (Lidl
plus the former HSS site), it will result in an increase in the sales area attributed to the Lidl food
store of 290m2 that represents an increase in sales area above the existing store of 26%.
4.13 For existing developments an increase in floor areas does not result in a pro-rata increase in
customers visiting the site. Retailers who increase the retail area of existing premises typically
expect a proportional increase in customers of up to 30% i.e. a 100% increase in floor area
results in a 30% increase in customer numbers and takings. The main reasons for this are:
• A number of trips to the new retail space are made by existing customers, with existing
customers staying longer;
• An increase in floor area enables a retailer to display more lines of a product, thereby
offering more choice to customers; and
• Extensions or the redevelopment of existing stores are often proposed to keep pace with
competing facilities, and if improvements are not made existing custom is lost.

4.14 Further more, as detailed in the CSS Wales Parking Standards 2008 to which the principles
noted within this document have been signed up to by the 22 Welsh Unitary Authorities and the
four regional transport consortia identified that;
‘Increases in transactions at supermarkets are not proportional to increases in
floor area. Increases of 33% of floor area typically produce a 10% increase in
transactions’
4.15 On this basis a 26% increase in sales area could potentially result in an increase in trip
attraction to the site of up to 8%, although based on more recent studies undertaken at other
food retail developments this figure is likely to be lower i.e. no material increase in trip
attraction to the site to only a 5% increase in trip attraction to the site.
4.16 However, in order to ensure the analysis is robust a theoretical exercise has been undertaken
whereby the traffic generated by the site has been increased by the upper figure of 8%.
Therefore, an increase in arrivals and departures of 8% above the baseline has been assumed
across the board for Friday and Saturday. The effect of this is summarised in Tables 4.1 and
4.2.

4.17 The development proposals will incorporate the land formally occupied by the ‘HSS’ site and
therefore as this site will no longer be operational as a result of the development proposals
there will be no trip attraction associated with this element of the site. The net change in trip
attraction between the observed ‘HSS’ trip attraction and proposed uplift in trip attraction
associated with the proposed Lidl store is shown in Tables 4.3 and 4.4.

4.18 Tables 4.3 and 4.4 indicate that as a result of the development proposals there would be an
overall net decrease (i.e. -18) in trip attraction to the site on a Friday and a relatively small
increase (+84) in trip attraction on a Saturday.

4.20 The information shown in Tables 4.5 and 4.6 indicate that based on the worst-case
assumption, that the redevelopment proposals would result in a 8% increase in trip attraction
to the site, the effect on the adjoining highway network would see an overall reduction in trip
attraction during a weekday including the AM and PM peak periods and a negligible increase
(i.e. maximum 15 two way vehicle movements in any hour) on a Saturday.
4.21 It should also be noted that the trip attraction surveys undertaken at the existing Lidl store do
not account for ‘pass-by’ or ‘linked’ trips. Although it would be incorrect to state that an
increase in sales area does not result in increased trip attraction, the results do support the
case that existing food retail store have a defined catchment and that increases in the sales
area of a store do not result in material or pro-rata increases in vehicle trips.
4.22 Therefore, the view that the redevelopment may result in an 8% increase in store related traffic
is likely be an overestimation and can be considered to be a robust case for assessment
purposes. This of course does not account for any reduction in additional trip attraction post
redevelopment relating to ‘pass-by’ trips where it is reasonable to assume that between 30%
and 40% of the 8% of new trips to the Lidl Store are already on the highway network passing
the site.
4.23 Moreover, it has been assumed that the proportional increase in customers is directly related to
car occupancy i.e. of 1 per car. In reality there is likely to be a car occupancy ratio of circa 1.3
or more.

Forecast Parking Utilisation
4.24 Based on the forecast trip attraction to the site as a result of the redevelopment proposals, an
assessment has been made on the suitability of the proposed parking provision for the store. As
noted in Section 3, it is proposed that the store will provide 91 parking spaces including 6
disabled spaces and 4 parent and child spaces.
4.25 Based on the forecast trip attractions shown in Tables 4.5 and 4.6, which accounts for the
additional post redevelopment parking accumulation, the peak parking accumulation for the
store is forecast to be 79% (14:30-14:45) during Saturday. Figures 12 and 13 show the
forecast parking utilisation for the site based on the foregoing judgements.

4.26 Based on this assessment it is evident that there will be sufficient parking provision within the
store to cater for any potential increase in customers post redevelopment.
Junction Capacity analysis
4.27 It is considered that as there is forecast to be a net decrease in vehicle trip attraction to the
proposed store on a weekday AM and PM peak period and a very minor change in trip attraction
to the site (i.e. 15 two way vehicle movement) for the Saturday peak period, junction capacity
assessments would not be required and have therefore not been undertaken at either the site
access or local highway network in the vicinity of the site on the basis that the redevelopment
proposals would have a negligible effect with regard to change in vehicle movements on the
adjoining highway network.
Conclusion
4.28 This chapter has summarised the methodology that has been applied to estimating the
additional traffic demand, which may arise following the redevelopment of the Lidl store.
4.29 Whilst the TRICS database would usually be used to calculate traffic demand from a
development, this is not a new store and the incremental effect of increases in sales area is not
considered in any substance or evidence within this database.
4.30 There is an existing demand for the store which will continue to be served by the store once the
redevelopment of the site is complete. At the same time, the proposed increase in floor area is
primarily focused on improving the offer to existing customers rather than significantly
increasing the catchment of the store.
4.31 The extent of the increase is typical of a modern store redevelopment and will include all of the
usual additions and enhancements that Lidl would typically wish to make. Amongst these are
increased storage facilities and backroom functionality
4.32 On this basis, it is considered that the appropriate starting point for determining the additional
trip generation associated with the proposed redevelopment of the site should be observed
traffic data from the existing Lidl store.
4.33 Although we have assessed a 8% uplift in trip attraction to the store, we are of the opinion that
it could be even less based recent research shows that the actual increase in customer numbers
post redevelopment of a food store site may be lower than 5%.

4.34 Based on the evidence presented in the foregoing, the assessment has therefore assumed an
8% uplift in Lidl related traffic movements and this is considered to be robust.
4.35 On this basis, it is considered that during peak periods, it would be realistic to assume that a
large proportion of trips associated with the development of a food store in this location would
already be on the highway network in the vicinity of the site and therefore not new trips.
4.36 The development proposals will see the removal of the former ‘HSS’ site and the trip attraction
associated with the use of this site, and on this basis, there is forecast to be net decrease in trip
attraction to the site on a Friday and only a small net increase in trip attraction on a Saturday.
4.37 It is considered therefore that the proposals will have a negligible impact on the highway
network in the vicinity of the site.

5 SUMMARY AND CONCLUSIONS
5.1 Go-surveys limited have been commissioned by Lidl UK GmbH to provide traffic and transport
advice in support of their planning application for the redevelopment of their existing store and
adjoining former ‘HSS’ site north of Colchester Avenue, Cardiff.
5.2 The development proposals for the store will result in a decrease in the total GIA of the entirety
of the site from 2,726m2 to 2,548m2 and a decrease in the total sales area of the site from
1,589m2 to 1,424m2.
5.3 The development proposals will see the position of the store within the site largely unchanged,
although changes will be made to the servicing arrangements and car park, the latter
incorporating the acquisition of the former ‘HSS’ site to provide an increase in the parking
provision within the site. The primary aim of the proposed redevelopment is to improve the
retail offer and shopping environment for existing customers and to increase the parking
provision within the site.
5.4 The proximity of the store to a number of residential catchments, coupled with the provision of
good cycle, pedestrian and public transport links make the store extremely accessible by all
modes of sustainable transport, therefore reducing its overall traffic impact on the local highway
network.
5.5 The trip attraction and parking accumulation analysis have shown that the car parking
proposals at this store will have a beneficial effect in terms of the overall operation and capacity
of the car park.
5.6 The assessment of the worst case scenario of an increase in trip attraction to the site of up to
8% following the redevelopment will have a negligible effect on the performance of the local
highway network with the addition of the development traffic during both the Highway and
retail peak periods.
5.7 In conclusion, as the residual cumulative impacts of the proposed development are considered
to be negligible there should be no reason from a transportation viewpoint why planning
consent relating to the proposed redevelopment of the site should not be granted.
