4 1. ntroduction 1.1 This report assesses the traffic and highway issues associated with a proposed development in Bangor. 1.2 The development site is located in Pen y Ffridd and lies between Caernarfon Road and Penrhos Road on current unused University and farm land (Figure 1). The site is allocated for Residential use in the Gwynedd Unitary Development Plan. 1.3 The Gwynedd UDP is supported by Development Briefs in the Council s Adopted Supplementary Planning Documents. n the case of this site it is a requirement that the site should be accessed solely from Caernarfon Road via the Menai Retail Park access until such time as the spine road of the development is extended to connect to Penrhos Road at the northern end at the Hospital access (which would be converted to a 4 arm roundabout). 1.4 This requirement is intended to reduce additional traffic use of the section of Penrhos Road between the Hospital and Caernarfon Road which has schools, onstreet parking, and is narrow in several places resulting in single file operation. Clearly there would be some use of Penrhos Road by occupiers of the new properties going to the Hospital and schools etc, but by limiting access to Penrhos Road until the spine road becomes a link road between Penrhos Road and Caernarfon Road (which should result in a reduction in the existing use of the critical section of Penrhos Road) increased traffic use of Penrhos Road will be minimised. 1.5 The development site would be therefore initially be accessed from Caernarfon Road via the roundabout that has been created for the Menai retail park which was designed from the outset to accommodate the proposed development and operate as the terminus of a link road. The access road has been granted planning consent which was recently renewed. 1.6 The proposed development would consist of residential units in a mix of sizes with a total provision of around 366 dwellings. 1.7 This report assesses the traffic and highway implications of the proposed development in the worst case scenario when all 366 dwellings are serviced from Caernarfon Road. Accessibility by other modes of transport (which in the case of pedestrian and cycle access is not restricted only to Caernarfon Road) is considered to demonstrate that the development complies with current Welsh Assembly and Local transportation planning policies

5 2.0 Surrounding Highway Network Details 2.1 The site in relation to the surrounding highway network is shown in Figure The site is bounded to the south east by the rear of retail properties on Caernarfon Road. To the north the site is bounded predominantly by residential development accessed from Penrhos Road with the Hospital to the west. 2.3 The former University buildings on the site (now cleared) were access from Penrhos Road via Pen y Ffrid Road. This access will no longer be used by vehicles, reducing the potential vehicle use of Penrhos Road, but this access will be used by pedestrians and cyclists. 2.4 Caernarfon Road is part of the A4087 an connects Bangor town centre to the northeast to the A55 North Wales Expressway to the south west (Junction 10), continuing beyond the A55 to the A487 North Wales Coast Road and to Caernarfon. t is a wide single carriageway in the vicinity of the development site. 2.5 The development would use the roundabout created for the existing retail park which forms the south eastern boundary of the site. This was designed and approved to serve the site and the future link road to Penrhos Road. 2.6 Penrhos Road connects the town centre to the north east (becoming Penchwintan Road at the north eastern end) and the A487 / A55 Junction 9 to the west. t also serves the Gwynedd Hospital. Between the Hospital and the town centre it is a relatively narrow road (very narrow in places) with frontage development. 2.7 Both Caernarfon Road and Penrhos Road are bus routes with stops close to the development site. 2.8 Caernarfon Road and Penrhos Road are part of the Bangor cycle network with a shared footway./ cycle way running past the site on the north eastern side of the Caernarfon Road carriageway. 2.9 There are a number of connecting roads between Caernarfon Road and Penrhos Road which have been traffic calmed and restricted to light vehicle use The site has good vehicle and alternative mode accessibility to the town centre and the surrounding area

6 3. Existing Travel Patterns in Bangor 3.1 The National Trip End Model (Tempro V6.2 / Dataset 62) has been used to determine the current (2013 levels) modes of transport used in Bangor for all trip purposes in comparison with the County and National Assembly travel patterns. The results are shown in Table 3.1 below. 3.2 As can be seen treating Bangor as a whole trips made on foot are lower than the County or Assembly averages. With good pedestrian links and a large foodstore within easy walking distance, the number of trips made on foot from the proposed development would be expected to be higher than the Bangor average and probably higher than the County and Assembly averages 3.3 The same is also the case for cycling trips. Here, however, the site s location directly adjacent to the Bangor cycle network with an off-carriageway cycleway along Caernarfon Road is likely to result in greater cycle use. 3.4 More trips are made by public transport in Bangor compared to the County and the Assembly averages. With public transport routes passing the site on Caernarfon Road and Penrhos Road the percentage of trips associated with the development by Public transport should be even higher. Table 3.1 Modes of Travel for all trips in Bangor, Gwynedd and the whole of Wales Mode Bangor Gwynedd Wales Weekdays Walk 26.01% 26.94% 28.48% Cycle 1.59% 1.73% 1.92% Car Driver 43.39% 43.63% 42.19% Car Passenger 19.01% 19.71% 19.83% Bus 8.26% 6.76% 6.27% Rail 1.74% 1.23% 1.31% Saturdays Walk 25.05% 25.13% 25.94% Cycle 1.43% 1.49% 1.60% Car Driver 38.92% 39.34% 38.15% Car Passenger 27.75% 28.43% 28.62% Bus 5.73% 4.80% 4.81% Rail 1.12% 0.81% 0.88% - 3 -

7 4.0 Pedestrian Accessibility 4.1 The National Assembly s Technical Advice Note 18: Transport (TAN 18) requires the needs of pedestrian highway users to be given high importance when assessing proposed developments. 4.2 The site is within easy walking distance of a wide surrounding catchment area. 4.3 TAN 18 is silent on acceptable walking distances (as what may be acceptable in one area may not in another due to topography considerations). The DTLR publication By Design: Better Places to Live, A companion guide to PPG3 advises that when considering new residential development the area within 10 minutes walking time or 800 m walking distance should be examined to determine the range of facilities which residents could access comfortably on foot. This is also the preferred maximum walking distance for town centre journeys on foot as advised by the nstitution of Highways and Transportation in their publication Guidelines for Providing for Journeys on Foot. 4.4 Before being replaced by the National Planning Policy Framework, PPG13 advised that walking was the most important mode of travel at the local level and offered the greatest potential to replace short car trips, particularly under 2 kilometres. Assuming a round trip of 2 km for say a shopping trip, a single-way walking distance of 1 km would, therefore, be considered acceptable. 4.5 The site location and the areas within a 800 m. and 1 km. radius are shown in Figure 3. This and the following diagrams indicate as the crow flies distances. The science behind the derivation of these distances is far from exact and any more detailed catchment areas would not have any greater reliability (in fact less by indicating with what may appear to be accuracy areas that would not be within walking distance which may be just a short distance beyond the boundary from where pedestrians could walk to the site). 4.6 As can be seen the Hospital, Tesco store and many other facilities on Caernarfon Road; schools on Penrhos Road and other local facilities lie within these comfortable walking distances. 4.7 At the time this advice was given the National Travel Survey showed that the average distance covered by a walking trip was 0.6 miles (approx 1km). The latest results from the National Travel survey show this to be 0.7m so the above distances could justifiably be increased which would result in even more facilities coming within the typical walking catchment area. 4.8 For employment trips a 2 km walk in each direction would be appropriate and this is also the preferred maximum walking distance for commuting journeys on foot as advised by the nstitution of Highways and Transportation in their publication - 4 -

8 Guidelines for Providing for Journeys on Foot. The area within such a catchment is shown in Figure 4. This covers the south western half of Bangor and Menai Bridge area of Anglesey. 4.9 A new footpath connection will be provided to Penrhos Road via Pen Y Ffridd Road as part of the development. The existing footpath running along the Hospital boundary can also be used to access the site. This latter footpath continues to Caernarfon Road but the last section is uninviting to pedestrians. As part of the development the spine road (from Caernarfon Road) will be provided with high standard footways which would provide an equivalent route at a gentler gradient. The spine road would be illuminated enabling this footway to be used in safety at all hours With the number of trips on foot in Bangor being around 60% of the number of trips by car in the week (Table 3.1), by factoring the expected car trips the proposed development could be expected to generate (section 6.4 below) around 520 trips on foot per day. n the am and pm peak hours, around 100 two-way trips respectively could be expected with these spread over the Caernarfon Road and Penrhos Road approaches There are crossing facilities provides on all arms of what will become the site access roundabout. Footways in this area are in general wide and in good condition. There should be no problems with this predicted level of pedestrian activity The site is clearly accessible on foot and the location in relation to the surrounding areas is likely to encourage trips to be made on foot and a potential reduction in car use

9 5. Public Transport Accessibility 5.1 The site is well served by existing bus services with Caernarfon Road and Penrhos Road both being bus routes. 5.2 Bus Services in the area and their frequencies / areas served are as follows: Table 5.1 Bus Services Serving Development Site Service Frequency Area Covered 1/1A min Mon-Sat Bangor Caernarfon - Porthmadog 5A 1 am and 1 pm peak Bangor Caernarfon Nantile hour service Mon-Fri 5B 4 services / day Bangor Bethel Caernarfon Mon-Sat 5/X5/5C/5S 20 min Mon-Sat Llandudno Bangor Caernarfon 6/6A 2 services / day Bangor Bethesda Mynydd Llandygai Mon-Sat 7/67C 3 services / day Bangor Tregarth - Bethesda Mon-Sat min Mon-Sat Bangor Caernarfon 72 4 services / day Bangor Felinheli - Bethel Mon-Sat 79 1 service / day Bangor Parc Menai Mon-Sat min Mon-Sat Bangor Llanrug - Llanberis 5.3 There are bus stops close to the site on Caernarfon Road and Penrhos Road. n the case of the Caernarfon Road stops there are stops on each side of the roundabout that will provide access to the site. The stops have raised boarding points and timetable displays. 5.4 On Penrhos Road again there are stops on either side of Pen Y Ffridd Road which will provide the main pedestrian access to the site. All stops have raised boarding points and timetable displays. The north east bound stop on the south western side of Pen Y Ffridd Road also has a shelter

10 5.5 There are also additional stops at the Gwynedd Hospital which acts as a small bus interchange. 5.6 With the number of trips by public transport in Bangor being around 19% of the number by car in the week (Table 3.1), as in the case of the expected trips on foot, by factoring the expected car trips the proposed development could be expected to attract around 165 trips by public transport per day. n the am and pm peak hours, 32 two-way trips by public transport could be expected respectively. 5.7 This level of increased public transport demand will be capable of being accommodated by the existing bus services. 5.8 t is clear that the site has very good public transport accessibility and is well located in accordance with current transportation planning policies

11 6. Vehicle Accessibility 6.1 The proposed development would consist of around 366 residential units. The development would be mixed houses (ranging from terraced to semi- and detached properties) and apartments. i. Assessment Periods 6.2 The worst case time periods for assessing a proposed residential development are invariably the weekday peak periods which for traffic generation purposes have been assumed to be and ii. Development Traffic Effects 6.2 The traffic generation potential of the development has been estimated using trip rates derived from the TRCS database. This is a national database of survey information collected at developments of different types with the observed arrivals / departures converted to trip rates (the number of trips per dwelling in the case of residential sites) so they may be used to estimate the likely traffic generation of development of different sizes. 6.3 A search of the recently updated database for surveys from 2002 to date at Mixed Private Residential Sites with dwellings in all parts of the UK excluding Greater London and reland gives the output reproduced in Appendix A. For the peak hour flows average trip rates (which by definition give the likely traffic generation of the proposed development, and 85 th percentile rates (which are statistically unlikely to be exceeded) have been extracted from the database to give likely and worst case flows. To give further robustness the 85 th percentile arrival and departure rates have been calculated. For the daily effects average rates are the only rates available from the database. 6.4 On the basis of the trip rates from Appendix A, the proposed 366 dwellings could, be expected to generate the traffic flows shown in Table 6.1 below

Daily rates derived from 2-way rates / 2 to ensure arrivals match departures iii. Distribution Pattern 6.5 n the worst case situation all traffic associated with the development will use the vehicle access to the site via the existing Retail Park roundabout on Caernarfon Road. From here traffic can travel north east to the town centre, or south west to the A55 / A4087 (and A487 beyond). At the A55 / A4087 junction traffic can travel on the A55 to the (north) west and east or continue on the A4087 to the A487 (south). 6.6 Most of the local traffic using the A4087 to the northeast will continue into the town centre but there could be some very localised trips that will stay in the immediate area or use Ffordd Coed Mawr to Penrhos Road to go to local schools or the Hospital. 6.7 The National Trip End model shows that trips made in Bangor in the weekday peak hours are likely to be made up of the trip types shown in Table 6.2 below

The only data available for these figures is still the 2001 census data (2011 Census Data not yet released for these trips) but there should not have been any material changes in the intervening period. There is no equivalent data for the other trip types. iv. Effects of Development 6.9 On the basis of the above figures the traffic that could be generated by the development would therefore consist of the trip types shown in Table 6.3 below By considering the distribution of employment trips from the Dewi ward and the total employment trips for the various time periods and directions of flow, the effects of the employment traffic generation of the development would be as shown in Table 6.4 and diagrammatically in Figure

14 Table 6.3 Trip Types and Total Traffic Generation of Proposed Development Time Arrivals Departures Ave. Ave. Worst Worst Ave. Ave. Worst Worst Work Other Case Case Work Other Case Case Trips Trips Work Other Trips Trips Work Other Trips Trips Trips Trips Weekdays The remaining trips would be a mixture of shopping, education, private business, visits to friends / relatives etc. The journey to work trips showed that around 16% of all employment trips were local (i.e. did not leave Dewi Ward). The same, if not a higher percentage, would be expected for the other trips. Shopping trips account for around 21% of the other trips in the am peak hour and around one third of the other trips in the pm peak hour The majority of these other trips would be expected to be made to the town centre and the nearby Tesco store to the south of the site, but there could be out-patient / visitor trips to the Hospital and some long distance trips via the A55. For this assessment it has been assumed that 16% of the trips are local with 10% going to the Tesco. Of the remaining trips 10% have been assumed to go to the Gwynedd Hospital (in this case assumed to use Ffordd Coed Mawr), and 10% use the A55 North, A55 South, and A4087 / A487 routes. The remaining trips are assumed to travel towards the town centre. These assumptions results in the effects shown in Figure The total effects of the development would be as shown in Figure 7 being a combination of the effects shown in Figures 5 and As can be seen from Figure 7, the effects of the development to the southwest of the access will be minimal. The Tesco roundabout and the A55 junction will not experience any noticeable difference as a result of the additional traffic the development is likely to add to the highway network in this area (even on the basis of the worst case 85 th percentile trip rates). These junctions have not, therefore, been considered further in this assessment The greatest effects of the development are likely to be to the north of the site access. The site access and Penchwintan Road junctions with Caernarfon Road have therefore been assessed in detail as part of this assessment

16 v. Base Traffic Flows 6.15 Current traffic flows at the site access and Penchwintan Road junctions with Caernarfon Road are shown in Figure 8 taken from surveys undertaken in November 2012 at the site access and February 2013 at the Penchwintan Road junction The Department for Transport in their Guidance on Transport Assessment advise that assessments of proposed developments should be undertaken at a design year 5 years post the date of the planning application for the development on the local road network, and 10 years post the date of the application for the Strategic Trunk Road network. Whilst the A4087 Caernarfon Road is not a Trunk Road, to provide a robust assessment a 10 year horizon has nevertheless been allowed for, i.e Expected peak hour traffic growth for classified roads in Bangor has been extracted from the National Trip End Model output presentation program (TEMPRO) as below. Table 6.5 Traffic Growth 2012/ Time Growth Growth AM peak hour 8.0% 7.96% PM peak hour 8.02% 7.94% 6.18 Base flows at 2023 would therefore be as shown in Figure n addition to general traffic growth, it has been assumed that the proposed residential development on the Rear of Ffordd Cynan site is approved (application currently undecided at time of writing). For this assessment the traffic that scheme s supporting assumed would be added to Penhros Road at the southern end remains on Penhros Road and passes through the Caernarfon Road / Penchwintan Road junction n a review of that scheme s undertaken last year it was considered that the traffic the scheme would add to Penrhos Road had been underestimated. We are aware that there were queries raised over this assessment by the local highway authority and the Assembly but no new information has been put into the public domain since an update to the was issued in January Whilst the traffic added to the southern end of Penrhos Road may have been under-estimated, assuming that all of this will pass through the Caernarfon Road / Penchwintan Road junction (when there will be traffic

17 leaving / joining the route at intervening junctions) should still give a robust assessment The effects of the Rear of Ffordd Cynan scheme are shown in Figure 10. Total 2023 base flows allowing for this scheme would therefore be as shown in Figure 11. vi. Design Traffic Flows 6.22 Total design traffic flows at the two junctions to be assessed are as shown in Figure 12, being the combination of the base flows allowing for the Rear of Ffordd Cynan site development from Figure 11 and the effects of the development from Figure 7. For this assessment the worst case flows (derived from 85 th percentile trip rates) have been used. vii. Junction Assessment i. Caernarfon Road / Site Access 6.23 This standard roundabout junction has been assessed using the Department of Transport ARCADY program. The results are reproduced in Appendix B and summarised below. Table 6.6 Performance of Site Access Arrangements under 2023 Traffic Flows Junction Arm Max RFC Max Ave.Queue % veh.

18 ii. Caernarfon Road / Penchwintan Road 6.27 This junction has recently been converted to a mini-roundabout to make right turn ingress and left / right egress from Penchwintan Road easier. The current arrangements have been tested using 2023 Base flows plus the Rear of Ffordd Cynan development flows also using the Department of Transport ARCADY program. The results are reproduced in Appendix C and summarised below. As can be seen by 2023 the current layout would have little reserve capacity in the AM peak hour on the Caernarfon Road northbound approach Table 6.7 Performance of Caernarfon Road / Penchwintan Road Junction under 2023 Base Traffic Flows Junction Arm Max RFC Max Ave.Queue % veh.

The output is reproduced in Appendix D and summarised below. As can

19 be seen there would be no material difference in the performance of Caernarfon Road (south) and a large improvement in the performance of Penchwintan Road.

Such matters are not considered further in this assessment

20 7. Pedal Cycle Accessibility 7.1 Caernarfon Road and Penrhos Road are both part of the Bangor cycle network. 7.2 n the case of Caernarfon Road cyclists share the north western footway. On Penrhos Road the route is signposted for cyclists but there is no specific off-street provision. 7.3 t is usual to assume a maximum cycle distance of 5 km for shopping and employment trips. Assuming a total cycle distance of 5 km (i.e. 2.5 km each way) for a shopping or other local trip gives the cycling catchment area indicated in Figure 13. As can be seen large part of Bangor and Menai Bridge containing most if not all of the local facilities a resident of the proposed development could need is therefore within easy cycling distance of the development site. 7.4 For employment trips it would be reasonable to assume a 5 km distance each way. Such a catchment area would be as shown in Figure 14. This covers the whole of Bangor and numerous other settlements. Cycling would clearly be an appropriate form of travel for employment trips. 7.5 With the number of trips by cycle in Bangor being around 3.7% of the number by car (Table 3.1), as in the case of the expected trips on foot, by factoring the expected car trips the proposed development could be expected to generate around 30 trips by cycle per day. 7.6 nternal footways and footpaths will be designed to accommodate shared pedestrian / cycle use as the scheme develops. The footpath connections to Penrhos Road will also be designed to accommodate shared use. No additional specific cycle provision is deemed necessary. 7.7 The site is clearly accessible by this mode of transport and the development will encourage this mode for local and employment trips as an alternative to the car

21 8. Conclusions 8.1 The site is within easy walking distance of a wide surrounding catchment area and the existing Tesco store opposite the site. 8.2 The proposed development will therefore be accessible on foot and will encourage walking as a mode of transport for small shopping trips. 8.3 The proposed site access arrangements will function satisfactorily even allowing for traffic growth to at least 2023 levels. 8.4 Remote from the site the worst case effects would be at the Caernarfon Road / Penchwintan Road junction which will be approaching its design capacity by 2023 regardless of the proposed development. The development will provide improvements to this junction to mitigate its effects. These improvements will also benefit users of Penchwintan Road. 8.5 The site has good public transport connections to the surrounding area and the town centre with a significant number of frequent services passing the site. 8.6 The site is adjacent to the Bangor cycle network. The site s footway connections to Penrhos Road will be improved to accommodate cycle use. 8.7 All local facilities would be within this easy cycling distance of the development site. The site is clearly accessible by this mode of transport and the development will encourage this mode for local and employment trips as an alternative to the car. 8.8 t is concluded that the site is accessible by a choice of modes of transport and that there are no highways / traffic related reasons why the proposed development should not be approved
