TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

1.0 Introduction

1.1 Introduction

1.1.1 This Transport Assessment (TA) has been prepared by Curtins on behalf of Taylor Wimpey UK Ltd (“Taylor Wimpey”) in connection with an outline planning application for residential development of up to 195 dwellings on land to the north of Dilworth Lane, Longridge.

1.1.2 A previous version of this report was originally prepared in support of an outline planning application (LPA ref. 3/2014/0517) that was submitted to Ribble Valley Borough Council (RVBC) in June 2014. The application was made for the development of up to 220 dwellings with all matters reserved, save for access from the adopted highway at land to the north of Dilworth Lane, Longridge.

1.1.3 Following a recommendation for approval by Planning Officers at RVBC, the application for 220 dwellings was heard at RVBCs Planning and Development Committee on 13 November 2014. Members voted in favour of refusing the application on the grounds that the proposed development would have unacceptable landscape and visual impact implications.

1.1.4 Taylor Wimpey have revised the scheme by reducing the number of residential units to be delivered to 195 dwellings, increasing the depth of the landscape buffers that surround the site and limiting heights to 2 storeys. The proposed site area has not altered between the previous application and the revised scheme and all other aspects of the proposal remain unchanged.

1.1.5 In preparation for the submission of this application, the following revisions have been made to this document from the version that was submitted in support of the application for 220 dwellings, as follows:

 The TA has been updated to take into account the post submission comments that Lancashire County Council (LCC) Highways made with regard to the junction modelling contained in the earlier TA;  The TA includes the latest access drawings that were agreed with Highways Officers at LCC during post submission discussions in relation to the earlier application; and  The sensitivity test which considered the impact of 260 dwellings has been removed from the TA.

1.1.6 It should be noted that the analysis within the report still relates to 220 dwellings. It was considered unnecessary to update the analysis to reflect the reduction in dwellings proposed, as it represents a scenario which would have a greater, not lesser impact. Therefore, in concluding that the

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

development of the site for 220 dwellings would be acceptable, it can be concluded with even greater confidence that 195 dwellings would be acceptable.

1.1.7 In all other respects, the report is consistent with the originally submitted version.

1.2 Purpose of this Report

1.2.1 The TA has been prepared to inform Highways Officers at Lancashire County Council (LCC) and the Highways Agency (HA) with regard to all traffic and transportation matters associated with the development.

1.3 Scope of the Report

1.3.1 The information presented in this TA has been prepared following consultation with Highways Officers at LCC and the Highways Agency.

1.3.2 Scoping discussions with LCC consisted of meetings on the 23rd January, 21st March and the 30th April 2014. A formal scoping note was submitted on the 11th April and a response was received from LCC on the 23rd April. This document has addressed all matters raised during scoping, in addition to comments that were raised during the post submission period that related to the previous planning application.

1.3.3 Scoping discussions with the HA consisted of email correspondence in March/April 2014 and post submission discussions in relation to the previous planning application.

1.3.4 Following these discussions it was agreed that the report would include:

 A description of the existing highway network surrounding the site;  A summary of the development proposals for the site;  Details regarding the access strategy for the site;  Consideration of relevant transport planning policy;  A review of accessibility by sustainable modes of travel;  A review of highway safety on the network surrounding the site;  An assessment of the level of traffic generation associated with the development proposals based on TRICS;  An assessment of the highway impact at 11 junctions plus the site access;  Consideration of the B6243 ‘Grimsargh’ corridor between Longridge and the M6 Junction 31A; and  Consideration of any mitigation measures that would be required.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

2.0 Site Location and Highway Layout

2.1 Site Location

2.1.1 The application site comprises a parcel of land, measuring 10.02 ha in area. It is situated to the north of Dilworth Lane and is located immediately adjacent to the eastern extent of the built up area of Longridge. The extent of the area to which the application relates is shown on the enclosed site location plans (Plans 1 & 2) and is identified by the redline boundary.

2.2 Existing Use

2.2.1 The application site currently comprises open fields.

2.3 Existing Site Access

2.3.1 There is no existing formal access into the site, with a single gate onto Dilworth Lane providing access to the fields.

2.4 Surrounding Highway Network

Dilworth Lane B5269 2.4.1 Dilworth Lane borders the site to the south and extends between the junction with Lower Lane to the east and King Street to the west. Dilworth Lane meets Lower Lane and Blackburn Road at a priority controlled T-junction. Dilworth Lane meets King Street and Higher Road at a priority controlled T- junction.

2.4.2 Dilworth Lane is approximately 7m wide with a lit continuous footway on the northern side which varies between 1.5 and 2m. The road is currently subject to a 30mph speed limit.

2.4.3 A new residential development is currently under construction to the south of the site. The development, Dilworth Triangle, comprises c. 49 new homes and a new access point onto Dilworth Lane approximately 280m west of the junction of Dilworth Lane/Lower Lane.

2.4.4 The new access junction for the Dilworth Triangle site comprises a priority controlled T-junction with Dilworth Lane. As part of the developments S278/S106 works it is understood that there are proposals to implement two variable messaging speed signs on Dilworth Lane and improve the existing gateway feature on the approach to Longridge via Blackburn Road. The purpose of these improvements is to reduce speeds on the corridor and it is envisaged that these measures will be successful.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

Blackburn Road B6243 2.4.5 Dilworth Lane becomes Blackburn Road at the priority controlled T-junction with Lower Lane. Blackburn Road has a carriageway width of between 7-8m with a footway on its northern side which varies between 1.5 and 2m.

2.4.6 Within the vicinity of the site Blackburn Road is subject to a speed limit of 30mph for a stretch of approximately 140m to the east of the junction with Lower Lane. At this point the speed limit changes to the National Speed limit. At the point of the speed limit change there are existing red bar markings forming a weak gateway treatment on the approach into Longridge.

Lower Lane 2.4.7 Lower Lane extends south from the priority controlled T-junction with Dilworth Lane and Blackburn Road. Lower Lane has a carriageway width of between 7-8m in width and an existing footway of between 1.5m and 2m on its southern side.

2.4.8 Lower Lane is subject to 30mph speed limit.

2.4.9 Approximately 1km south of the Lower Lane/Dilworth Lane/Blackburn Road junction, Lower Lane meets Chapel Hill at a priority controlled T-junction. Chapel Hill continues south towards Preston and the M6.

King Street 2.4.10 To the west of the site, Dilworth Lane becomes King Street at the priority junction with Higher Road. King Street is approximately 7-8m wide and is subject to double yellow line parking restrictions. There are footways on both sides of the carriageway.

2.4.11 Higher Road continues north to residential areas of Longridge and locations such as Chipping and other outlying areas.

2.4.12 King Street becomes Market Place at the junction with Berry Lane. Berry Lane continues into Longridge town centre.

2.5 Highway Safety

2.5.1 Personal Injury Accident (PIA) data has been obtained from Lancashire Constabulary for the period between the 1st February 2009 and the end of January 2014. The study area covers the following locations:-

 The Dilworth Lane/Blackburn Road/Lower Lane junction;  Dilworth Lane within the vicinity of the site;

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

 Blackburn Road within the vicinity of the site;  The Blackburn Road/Lower Road junction; and  King Street and Market Place.

2.5.2 There were 8 collisions within the study area over the most recent five year period, in which a total of 7 slight injuries and 1 serious injury occurred. A summary can be seen in Table 2.1 below.

Location Slight Serious Fatal Total

Dilworth Lane/Lower Lane/Blackburn Road Junction 1 1 - 2 Lower Lane 2 - - 2 Lower Lane/Chapel Hill 1 - - 1 Market Place 3 - - 3 King Street 0 - - 0 Total 7 1 - 8 Table 2.1 – Personal Injury Accident Data Summary

2.5.3 An analysis of the accident data has been undertaken and this is described below.

Dilworth Lane/Blackburn Road/Lower Lane Junction 2.5.4 There have been two reported PIA’s at the above junction within the vicinity of the site. The serious accident occurred in June 2010 and the slight occurred in June 2009.

2.5.5 The serious collision occurred when a vehicle failed to obey give way markings at the junction.

Lower Lane 2.5.6 There has been two recorded PIA on Lower Lane. One occurred at the priority junction with Risedale Drive and one just to the south of the junction with Highfield Drive.

2.5.7 The PIA at Risedale Drive was slight in nature and occurred when a vehicle turned right in front of another.

2.5.8 The serious PIA to the south of Highfield Drive occurred in the early morning when a passenger jumped out of a taxi.

Lower Lane/Chapel Hill 2.5.9 There has been one recorded PIA at the Lower Lane/Chapel Hill junction. This incident was recorded as slight in nature.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

Market Place 2.5.10 There have been 3 reported PIA’s on Kings Street and Market Place. Two of these incidents occurred at the junction with Berry Lane and one at the junction with Fell Brow. All of these incidents were slight in nature.

2.6 Summary

2.6.1 In summary, no significant correlations have been identified to suggest that highway condition, layout or design were significant contributory factors in any of the collisions within the study area. Furthermore, the frequency and severity of the accidents is not considered to be unusual and could be considered as good when compared to accident records at other locations in Lancashire.

3.0 Transport Planning Policy

3.1 Introduction

3.1.1 This section of the report sets out the key national and local traffic and transport policies that are relevant to this application. Later sections of the report demonstrate how the proposals accord with these policies.

3.2 National Planning Policy Framework

3.2.1 The NPPF sets out national transport planning policy and from the outset the Minister for Planning’s Foreword lays the foundations for the policy rationale;

‘The purpose of planning is to help achieve sustainable development….

Development means growth. We must accommodate the new ways by which we will earn our living in a competitive world. We must house a rising population, which is living longer and wants to make new choices. We must respond to the changes that new technologies offer us. Our lives, and the places in which we live them, can be better, but they will certainly be worse if things stagnate.’

3.2.2 Paragraph 14 states that at the heart of NPPF is:

‘A presumption in favour of sustainable development, which should be seen as a golden thread running through both plan making and decision making.’

3.2.3 For decision making a presumption in favour of sustainable development means granting permission:

‘Unless any adverse impacts of doing so would significantly and demonstrably outweigh the benefits, when assessed against the policies.’

3.2.4 In respect of supporting traffic and transportation documentation, Paragraph 32 of the NPPF states that:

“All developments that generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment. Plans and decisions should take account of whether:

 The opportunities for sustainable transport modes have been taken up depending on the nature and location of the site, to reduce the need for major transport infrastructure;

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

 Safe and suitable access to the site can be achieved for all people; and  Improvements can be undertaken within the transport network that cost effectively limit the significant impacts of the development. Development should only be prevented or refused on transport grounds where the residual cumulative impacts of development are severe.”

3.2.5 Paragraph 35 of the NPPF states that plans for new development should:

“protect and exploit opportunities for the use of sustainable transport modes for the movement of goods or people. Therefore, developments should be located and designed where practical to;

 Accommodate the efficient delivery of goods and supplies;  Give priority to pedestrian and cycle movements, and have access to high quality public transport facilities;  Create safe and secure layouts which minimise conflicts between traffic and cyclists or pedestrians, avoiding street clutter and where appropriate establishing home zones;  Incorporate facilities for charging plug-in and other ultra-low emission vehicles; and  Consider the needs of people with disabilities by all modes of transport.”

3.2.6 Paragraph 36 of the NPPF states:

“All developments which generate significant amounts of movement should be required to provide a Travel Plan.”

3.2.7 This TA has been accompanied by an Interim Travel Plan which provides a commitment to produce a full Travel Plan upon occupation of the completed development.

3.3 National Planning Policy Guidance

3.3.1 The Government has recently produced the National Planning Practice Guidance (NPPG) to supplement the NPPF. Within the PPG, there is a specific section clarifying the over-arching principles on Travel Plans, Transport Assessments and Transport Statements. There are also sections advising further on each of the three discussed documents.

3.3.2 The guidance on Transport Assessments and Statements re-iterates the circumstances in which either document would usually be required. It is clear that a development of the size and nature of this development requires a full Transport Assessment. It also clarifies the process for establishing a scope for the assessment, and what the document should contain. The NPPG has been considered in the production of this TA.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

3.3.3 The guidance on Travel Plans reinforces the requirement for a Travel Plan, the scope of the document, and need for monitoring to continue the strategy into the future. The NPPG has been considered in the production of the accompanying Interim Travel Plan.

3.4 Core Strategy Publication Version 2008-2028

3.4.1 From a traffic and transport perspective the Core Strategy includes two key statements. Key Statement DMI2: Transport Considerations states that:

‘New development should be located to minimise the need to travel. Also it should incorporate good access by foot and cycle and have convenient links to public transport to reduce the need for travel by private car. In general, schemes offering opportunities for more sustainable means of transport and sustainable travel improvements will be supported. Sites for potential future railway stations at Chatburn and Gisburn will be protected from inappropriate development. Major applications should always be accompanied by a comprehensive travel plan.’

3.4.2 Key Statement DMG3: Transport and Mobility states that:

‘In making decisions on development proposals the Local Planning Authority will, in addition to assessing proposals within the context of the development strategy, attach considerable weight to:

The availability and adequacy of public transport and associated infrastructure to serve those moving to and from the development –

 The relationship of the site to the primary route network and the strategic road network;  The provision made for access to the development by pedestrians, cyclists and those with reduced mobility;  Proposals which promote development in existing developed areas or extensions to them at locations which are highly accessible by means other than the private car;  Proposals which strengthen existing town and village centres which offer a range of everyday community shopping and employment opportunities by protecting and enhancing their vitality and viability; and  Proposals which locate development in areas which maintain and improve choice for people to walk, cycle or catch public transport rather than drive between homes and facilities which they need to visit regularly…..’

3.5 Lancashire Local Transport Plan 3

3.5.1 The Lancashire Local Transport Plan 3 (LTP) presents transportation priorities for ten years from 2011 to 2021. It sets out a strategy which pledges to support the Lancashire economy, tackle deep-seated

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

inequalities in people's life chances and to revitalise communities by providing safe high-quality neighbourhoods.

3.5.2 The LTP sets out the following ‘Priorities and Activities:

 Improving Access into Areas of Economic Growth and Regeneration;  Providing Better Access to Education and Employment;  Improving People's Quality of Life and Wellbeing;  Improving the Safety of our Streets for our most Vulnerable Residents;  Providing Safe, Reliable, Convenient and Affordable Transport Alternatives to the Car;  Maintaining our Assets; and  Reducing Carbon Emissions and its Effects.

3.5.3 It is considered that the development proposals accord well with the priorities set out in the LTP, particularly with regard to improving access and connectivity to key facilities.

3.6 Central Lancashire Highways and Transport (2014)

3.6.1 The Highways and Transport Masterplan for Central Lancashire is the County Council’s vision for developing the transport network in South Ribble, Preston and Chorley over the next 15 years. Whilst the document does not cover the Longridge area there are improvements proposed that are relevant to this application.

3.6.2 The key improvement in relation to this application are the proposals to improve M55 Junction 1 and the Broughton Bypass. According to the CLHTM, the M55 Junction 1 and Broughton Bypass improvements would achieve the following:

 Significant reduction in delay to, and so improved journey reliability for, traffic using the Broughton junction;  A marked reduction in the amount of queuing traffic in the village, along all current approaches to the Broughton crossroads and with it an improvement in air quality and noise levels;  Improved access and safety for vulnerable users in the village; and  Additional facilities to promote more walking and cycling in the village.

3.6.3 In respect of delivery of the CLHTM, the Preston and Lancashire City Deal has been approved by the government, and will result in a total of approximately £434m of funding to support economic development and housing sites within the City Deal area. This provides certainty that the infrastructure improvements can be funded and will be delivered.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

3.6.4 Whilst the traffic associated with the proposed development travelling through the Broughton crossroads and M55 Junction 1 is envisaged to be minimal, it is worth noting that there is an identified improvement scheme to improve the route and parts of this are already being implemented.

3.7 Summary

3.7.1 The key theme of sustainability is considered further in Section 5 of this report. With regard to highway impact the results contained in Sections 7-9 demonstrate that the impact could not be classed as severe.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

4.0 Development Proposals

4.1 Introduction

4.1.1 The proposals for land to the north of Dilworth Lane comprise a residential development of up to 195 units with associated access, parking, landscaping and amenity space. The planning application will be submitted in outline and an indicative layout of the development is shown on the Illustrative Masterplan included as drawing 492D 03 to the rear of this report.

4.1.2 This section of the report provides information regarding the development proposals and should be read in conjunction with the Design and Access Statement prepared by Randall Thorp.

4.2 Vehicular Access

4.2.1 In determining the location and form of the site access Curtins has liaised extensively with Highways Officers at LCC and residents at a public consultation event that was held in April 2014.

4.2.2 As a result of the above discussions, it is proposed that a new priority controlled access will be provided on Blackburn Road to the south east of the site, as shown on Drawing Number TPMA1178/011L.

4.2.3 The location of the access has been chosen to minimise the traffic impact on existing residential properties and Longridge town centre. The proposed location is situated well away from existing development on Dilworth Lane and it is envisaged that a significant proportion of the development traffic will arrive and depart the site via Lower Lane rather than Dilworth Lane and via the town centre.

4.2.4 As Blackburn Road has a speed limit of 30mph, is not part of the trunk road network and will become an active residential frontage once the development is complete, the design of the access is based on guidance contained in Manual for Streets 1 and 2. On this basis a 6m carriageway is provided with 2m footways on both sides.

4.2.5 To determine appropriate visibility splays, speed surveys were undertaken in the vicinity of the proposed site access in August 2013. The results indicate wet weather 85th percentile speeds of 37mph in a westbound direction and 38mph in an eastbound direction. These speeds are potentially higher than expected for a 30mph road, but this is due to the survey location which was in close proximity to the point where the speed limit changes from 30mph to 60mph.

4.2.6 Speed surveys undertaken on Dilworth Lane in 2014, further to the west of the speed limit change, indicate significantly slower 85th percentile speeds in the region of 33mph for both westbound and eastbound traffic. All speed surveys are contained in Appendix B.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

4.2.7 To achieve speeds at the proposed access that are comparable to the remainder of Dilworth Lane, or even lower, it is proposed that the existing 30mph speed limit is relocated approximately 80m to the east. New red bar markings, a 30 mph roundel on red surfacing, gateway signage and minor narrowing of the carriageway will enforce the change in speed limit. It is also envisaged that the provision of a new access itself, and the VMS signs that are to be installed as part of the Dilworth Triangle site, will reduce speeds and ensure greater driver caution.

4.2.8 Whilst post development speeds cannot be determined at this stage it is envisaged that extending the 30mph zone will reduce speeds to a level comparable to Dilworth Lane. However, to ensure robustness visibility has been determined using 85th percentile speeds of 37mph and as a result splays of 2.4m x 60m are envisaged. Notwithstanding this it should be noted that visibility significantly greater than this could be achieved subject to additional hedgerow removal.

4.2.9 A 3.8m wide emergency access is also proposed at the western edge of the site adjacent to Dilworth Lodge. It is envisaged that this will be bollard protected to prevent general vehicular use, although it will allow for pedestrian/cycle connectivity. The emergency access is shown on Drawing Number TPMA1178/010E.

4.3 Sustainable Modes of Travel

4.3.1 The proposed vehicular access point mentioned above will include 2m footways on both sides of the carriageway. However, as the footpath along Dilworth Lane and Blackburn Road does vary in width and there is a desire to retain as much hedgerow as possible, a new 2m footway is proposed to the rear of the existing hedgerow. This footway will extend on an east/west alignment broadly parallel to the road and will provide regular connections to the highway to allow crossing or access to bus facilities.

4.3.2 The above footway will connect with Dilworth Lane at the westernmost point of the site where existing pedestrian infrastructure on the northern side of the carriageway provides a link to the town centre.

4.3.3 To enhance connectivity at the eastern end of the site a new pedestrian crossing facility is proposed on Blackburn Road to the west of the proposed access. This will provide a connection to a new 2m footway on the opposite side of the carriageway which will then connect to the existing footway on Lower Lane.

4.3.4 New footways within the site will connect with the existing bridleway on the eastern boundary which in turn provides access to PROW No35 and to Higher Lane to the north of the site. A new internal footway will also connect the site to existing PROW No33 which extends to the north of Spade Mill Reservoir.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

4.3.5 With regard to public transport, two new bus stops are envisaged to maximise benefits associated with the commercial services that operate along Blackburn Road. Whilst these stops are not strictly necessary to make the development sustainable they would be beneficial. The eastbound stop is envisaged at the eastern edge of the site and the westbound stop is envisaged on Lower Lane. Both stops will be connected to the site via new footway and a pedestrian crossing facility.

4.4 Internal Layout

4.4.1 The planning application is for outline permission with access and therefore all other matters such as internal layout will be subject to reserved matters applications.

4.4.2 Notwithstanding the above, the internal layout has been developed to a high level and further information can be found in the Design and Access Statement.

4.5 Parking

4.5.1 Car and cycle parking for the proposed development will be provided in accordance with LCC standards. This will be considered as part of the reserved matters application.

4.6 Phasing

4.6.1 The proposed development will be market led, but based on information provided by Taylor Wimpey it is likely to take approximately 5-7 years to be fully built out. This could result in a year of opening of 2020-2022.

5.0 Accessibility by Sustainable Modes of Travel

5.1 Introduction

5.1.1 One of the key elements of national and local planning policy, as detailed in Section 3 of this report, is to ensure that new developments are located in areas where alternative modes of travel are available. Developments should not be isolated but located close to complementary land uses. Encouraging the integration of planning and transport supports the aim of reducing overall travel and use of private car.

5.1.2 The accessibility of the proposed development is considered in this context for the following modes of travel:

 Pedestrian Accessibility;  Cycle Accessibility; and  Public Transport Accessibility.

5.2 Pedestrian Accessibility

5.2.1 Research has indicated that acceptable walking distances depend on a number of factors, including the quality of the development, the type of amenity offered, the surrounding area, and other local facilities.

5.2.2 The Chartered Institution of Highways and Transportation (CIHT) document entitled ‘Providing for Journeys on Foot’ suggests walking distances which are relevant to this planning application. These are reproduced in Table 5.1 below.

CIHT Category Town Centres (m) Commuting/School/ Sightseeing (m) Elsewhere (m)

Desirable 200 500 400 Acceptable 400 1,000 800 Preferred Maximum 800 2,000 1,200 Table 5.1 – CIHT Recommended Walking Distances

5.2.3 To assist in summarising the accessibility of the site by foot, an indicative pedestrian catchment plan has been produced. Plan 003 shows distances of 500m, 1,000m and 2,000m which are termed ‘Desirable’, ‘Acceptable’ and the ‘Preferred Maximum’ by the CIHT for commuting trips and school trips. However, it is also worth noting that the 2012 National Travel Survey states that 77% of journeys under a mile are made by foot.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

5.2.4 Plan 004 shows the key local services that are broadly located within these catchments.

5.2.5 Parts of the development site are located within 500m of the White Bull and the Corporation Arms Public Houses, and the eastern edge of Longridge town centre. This part of the town centre includes a dental surgery, a children’s nursery, some retail opportunities and Longridge Library.

5.2.6 The 1000m catchment taken from the centre of the site extends as far as Calder Avenue in the centre of Longridge. The catchment includes the facilities mentioned above, plus St Lawrence and St Pauls C of E Church, banking facilities, take-a-way facilities, retail opportunities, Longridge Church of England Primary School, a Post Office, a Co-operative foodstore, community facilities and medical facilities.

5.2.7 The 2,000m pedestrian catchment covers an even larger area of Longridge which includes the Langtree Community Hospital, Sainsbury’s supermarket, Longridge High School, Saint Cecilia’s Roman Catholic High School, Barnacre Road Primary School, Saint Wilfrid’s Roman Catholic Primary School and a wide variety of additional retail, community and leisure facilities.

5.2.8 The above facilities are accessible via a network of existing footways along Blackburn Road, Dilworth Lane, Lower Lane, King Street and Berry Lane. It is noted that there are numerous changes in topography on these routes, but this is not considered to be insurmountable for the vast majority of users.

5.2.9 In addition to the above routes there are also a number of additional routes in the vicinity of the site which further enhance connectivity and provide leisure opportunities. This includes:  Bridleway No35 along the eastern edge of the site;  Public Right of Way No36 to the north of the site;  Public Right of Way No33 to the north east of the site;  An extensive network of new footways/cycleways through the site including a new east-west route that could act as an alternative to Dilworth Lane/Blackburn Road; and  A footpath connection through the Dilworth Triangle site onto Lower Lane.

5.2.10 In summary, it is considered that there are a significant number of retail, employment, education, worship, health and leisure opportunities within walking distance of the proposed development. These are well connected to existing infrastructure and walking is therefore likely to be an attractive option for many future residents at the site.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

5.3 Cycle Accessibility

5.3.1 To assist in assessing the accessibility of the site by cycle, a 5km cycle catchment from the centre of the site is shown on Plan 005. The 5km distance equates to a journey time of around 25 minutes, while cycling at a speed of 12km per hour.

5.3.2 The 5km cycle catchment includes all of Longridge and extends to a number of surrounding areas including Grimsargh, Whittingham, Goosnargh and Ribchester.

5.3.3 Whilst there are no formal cycle lanes in the vicinity of the site a review of the Sustrans database and the LCC Maps and Related Information Online (MARIO) database indicates that Dilworth Lane and Blackburn Road are both designated as on-road cycle routes and form part of the Northern Loop Cycle Route.

5.3.4 The Northern Loop provides access to local facilities and extends through the centre of Longridge. However, it also extends to Whalley in the east, Blackpool in the west and Lancaster to the north.

5.3.5 In summary, it is considered that cycling is likely to be a realistic mode of travel for residents wanting to access Longridge, but also for residents who want to travel further afield as either a commuting or leisure based trip.

5.4 Public Transport Accessibility

Bus 5.4.1 The Chartered Institution of Highways and Transportation (CIHT) document, Planning for Public Transport in Developments recommends that developments should ideally be within 400m of a bus stop.

5.4.2 A review of the LCC MARIO database indicates that the nearest active bus stops are located on Dilworth Lane adjacent to Dilworth Lodge. The entire development is within 400m of these stops which are utilised by 4 school bus services (Mon - Fri). A summary of the services is provided below:

Bus Arrival Service Operator Route Times AM PM 106 Longridge Coaches Wilkingshire to Longridge High School 08:34 15:31 625 Pilkington Buses Billington St Augustines RC High School 08:06 15:58 876 Longridge Coaches Clitheroe Royal Grammar 07:48 16:28 995 Moving People Myerscough College 08:18 17:37 Table 5.2 – School Bus Services from Dilworth Lane

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

5.4.3 There are numerous other bus stops within the vicinity of the site, the first of which are located on King Street to the west of the site. These stops are located within 300m of the western boundary of the site. The stops are utilised by the number 4 which provides an hourly service between Longridge and Preston as indicated below:

Frequency Service Operator Route Weekday Saturdays 4 LCC Longridge – Whittingham – Fulwood – Preston 60 Minutes 60 Minutes Table 5.3 – Local Bus Services From King Street

5.4.4 An additional bus stop is located on Market Place which is approximately 400m from the western edge of the site and approximately 600m from the centre of the site. Whilst the distance to the bus stop will exceed 400m for some residents, the stop is served by the number 1 which provides a direct service between Longridge and Preston every ten minutes.

Frequency Service Operator Route Weekday Saturdays Sundays

Preston – Ribbleton – Grimsargh – 1 Stagecoach 10 10 30 Longridge Table 5.4 – Local Bus Services From Market Place

5.4.5 Guidance contained in the CIHT document, Planning for Public Transport in Developments states that ‘Direct simple bus services are more important than walking distances’ and therefore it is considered that many residents will be prepared to walk over 400m to access the number 1.

5.4.6 To the east of the site, there are two bus stops on Blackburn Road approximately 200m from the edge of the site and approximately 500m from the centre of the site . These stops are served by 4 different services which provide connections to destinations such as Chipping, Longridge town centre, Clitheroe, Garstang, Ribchester and Blackburn.

5.4.7 To ensure that the site gains maximum benefit from these services two additional bus stops proposed on Blackburn Road along the site frontage. This would ensure that the entire site would be within 400m of the services.

5.4.8 Plans 6 and 7 at the rear of this report show the routes of the various bus services and the stops that they utilise in the vicinity of the site.

5.4.9 In summary, it is considered that the site is well served by bus with a total of 4 school bus services and 6 commercial services within a reasonable walking distance of the site. The introduction of two additional bus stops on the site frontage will further reduce walking distances and improve the attractiveness of existing services.

5.5 Accessibility Score

5.5.1 To quantify the accessibility of a particular site, LCC Highways utilise a scoring methodology which is contained on their website. There is an assessment for residential uses and this has been completed for the existing site and the site post development. The full results are contained in Appendix C.

5.5.2 The results indicate that the site would currently score 23, with points mainly attributable to the proximity of the town centre and key facilities such as a public house, Post Office and bank. The site also scores well in relation to proximity to the cycle network and distance to nearest bus stop.

5.5.3 The results of the post development analysis indicate that the site could score 29 which is classed by LCC as ‘medium’ accessibility. The increased score is due to the introduction of a children’s play area within the site and the new bus stops that are envisaged at the eastern edge of the site.

5.5.4 Notwithstanding the above, it is considered that the LCC accessibility questionnaire underestimates the accessibility of the site, particularly with regard to the sites proximity to schools and food shops. For example, developments 600m or more from a primary school, 600m or more from a food store or 1km or more from a secondary school score no points. However, when comparing these distances to Table 5.1 above, it is clear that these thresholds are well within the acceptable levels as determined by the Chartered Institution of Highways and Transportation (CIHT).

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

5.6 Accessibility Summary

5.6.1 In summary, it is considered that the site is well located to benefit from existing pedestrian, cycle and public transport infrastructure in accordance with the key policies referenced in Section 3 of this report. The existing infrastructure provides access to a wide variety of key facilities and destinations both in Longridge and further afield.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

6.0 Traffic Forecasting

6.1 Introduction

6.1.1 This section of the report details the methodology used to predict the demand associated with the proposed development and derive future year traffic flows in order to test the impact of the proposed development.

6.2 Scope of Assessment

6.2.1 During scoping discussions with LCC and the HA it was agreed that the following junctions would require consideration;

 Blackburn Rd/Lower Rd/Preston Road;  Blackburn Rd/Lower Rd/Dilworth Ln;  Lower Ln/Chapel Hill;  Chapel Hill/Preston Rd;  King Street/Berry Lane;  Market Place/Kestor Lane;  Preston Road/Whittingham Road;  B6242/B6243 Longridge Road Roundabout;  A59 Longsight Road/Ribchester Road; and  The two roundabouts that form Junction 31A of the M6 (Highways Agency).

6.3 Traffic Surveys

6.3.1 Traffic surveys were undertaken at 10 of the junctions listed above on Tuesday 18th March 2014. The A59 Longsight Road/Ribchester Road traffic survey was undertaken on Monday 28th April 2014.

6.3.2 All surveys were undertaken between the hours of 0700 - 0900 and 1600-1800.

6.3.3 Following analysis of the traffic survey data, it was determined that the AM peak period on the highway network occurred between 07:45 and 08:45, whilst the PM peak occurred between 16:45 and 17:45. These peak hours have been used as the basis for this assessment.

6.3.4 Figures 1 and 2 at the rear of the report show the observed traffic count data.

6.4 Assessment Years and Traffic Growth

6.4.1 It has been agreed with LCC that capacity assessments on the local highway network should be based on the predicted build out rates and the year of completion. Whilst this is obviously dependent

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

on market conditions it is envisaged that the site could take between 5-7 years assuming standard build out rates.

6.4.2 Notwithstanding the above, the Highways Agency has requested an assessment of the strategic network for 2024 and on this basis all assessments are based on 2024. This represents a very robust assessment that is potentially several years following completion of the development and approximately twice that suggested in the DfT Guidance on Transport Assessment.

6.4.3 The observed traffic flows have been factored to the 2024 assessment year by the following methods.

6.4.4 For links and junctions within the Longridge and Grimsargh areas a growth factor has been taken from the National Traffic Model (NTM) with TEMPRO for the Longridge (main) area. For the junctions within the vicinity of the M6 Junction 31a factors have been taken from the NTM model for the Preston area. The resultant growth factors are shown in Table 6.1 below.

Area Base Year Forecast Year AM Peak PM Peak

Longridge (main) 2014 2024 1.134 1.137

Preston 2014 2024 1.152 1.150

Table 6.1 – NTM Growth Factors

6.4.5 The above factors equate to a 13% increase in traffic on all links in Longridge and a 15% increase on all links in Preston. The factors have been applied to the 2014 Base traffic flows and the resultant 2024 Factored traffic flows are shown in Figures 3 to 4 at the rear of this report.

6.5 Committed Development

6.5.1 In addition to the background growth, LCC requested that the traffic associated with recent committed developments is considered as part of the 2024 assessment year. Based on a review of recent planning consents in the vicinity of the site the following committed developments require consideration:

1. The Former Ridings Depot site (220 Residential Units, B1 Commercial Offices, C2 Residential Apartments with care and leisure facilities); 2. Mosses Farm, Whittingham Road (78 Residential Units); 3. Grimbledeston Farm, Preston Road (62 Residential Units); 4. Sprout Farm, Preston Road (32 Residential Units); 5. Land at Chapel Hill (52 Residential Units); 6. Dilworth Triangle (49 Residential Units); 7. Former Whittingham Hospital (650 Residential Units & 9,000m2 GFA of B1); and

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

8. Inglewhite Road Development (190 Unit Residential Development).

6.5.2 Traffic flows associated with the above committed developments have been derived from the associated Transport Assessments and Statements which accompanied the above planning applications.

6.5.3 Where traffic flows are not available (for example if the study area does not extend into that adopted within this TA, or no trip generation data is provided), then a series of assumptions have been made in terms of traffic generation and distribution. These are summarised below:

Former Ridings Depot 6.5.4 Traffic flows have been taken from the Ashley Helme Associates 2011 Transport Assessment 1242/2/C TA Figure E11. It is understood that these figures were agreed as part of the Ridings Appeal (ref: APP/N2345/A/12/2169598) Statement of Common Ground with LCC.

6.5.5 Where junctions from the above TA match the study area these flows have been directly transposed from the flow diagram. For other junctions within this study area the distribution pattern from the proposed development traffic distribution has been used to assign the traffic.

6.5.6 The resultant Former Ridings Depot committed development traffic flows are shown in Figures 5 and 6.

Mosses Farm, Whittingham Road 6.5.7 Traffic flows have been taken from the PBA May 2012 Transport Assessment R001/rev01 TA Figure 5.8.

6.5.8 Where junctions from the above TA match the study area these flows have been directly transposed from the flow diagrams. For other junctions within this study area the distribution pattern from the proposed development traffic distribution has been used to assign the traffic.

6.5.9 The resultant Mosses Farm committed development traffic flows are shown in Figures 7 and 8.

Grimbledeston Farm, Preston Road 6.5.10 No supporting TA or TS has been located for this site. On this basis the trip generation rates and trip distribution pattern assumed for the proposed development have been applied to the 62 units development quanta and assigned to the network.

6.5.11 The resultant Grimbledeston Farm committed development traffic flows are shown in Figures 9 and 10.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

Sprout Farm, Preston Road 6.5.12 Trip generation figures have been derived from the PSA Design Transport Statement (Table 4), which accompanied the planning application. As no traffic distribution pattern has been provided in the TS, the proposed distribution pattern adopted within this Transport Assessment has been used to assign the committed development.

6.5.13 The resultant Sprout Farm committed development traffic flows are shown in Figures 11 and 12.

Land at Chapel Hill 6.5.14 No supporting TA or TS has been located for this site. On this basis the trip generation rates and trip distribution pattern assumed for the proposed development have been applied to the 55 unit development quanta and assigned to the network.

6.5.15 The resultant Land at Chapel Hill committed development traffic flows are shown in Figures 13 and 14.

Dilworth Triangle 6.5.16 Trip generation figures have been derived from the Singleton Clamp Transport Statement (Doc ref WB/11033/070211), which accompanied the planning application. As no traffic distribution pattern has been provided in the TS, the proposed distribution pattern adopted within this Transport Assessment has been used for this committed development.

6.5.17 The resultant Dilworth Triangle committed development traffic flows are shown in Figures 15 and 16.

Former Whittingham Hospital 6.5.18 Traffic flows have been taken from the Ashley Helme Associates 2011 Transport Assessment 1242/2/C TA Figure E7. It is understood that these figures were agreed as part of the Ridings Appeal (ref: APP/N2345/A/12/2169598) Statement of Common Ground with LCC.

6.5.19 Where junctions from the above TA match the study area these flows have been directly transposed from the flow diagrams. For other junctions within this study area the distribution pattern from the proposed development traffic distribution has been used to assign the traffic.

6.5.20 The resultant former Whittingham Hospital committed development traffic flows are shown in Figures 17 and 18.

Inglewhite Road Development 6.5.21 A TA was prepared by Ashley Helme Associates in February 2014 to support the application (06/2014/0248). Curtins has obtained a copy of this report which contains traffic impact figures that clearly set out the predicted development traffic on the surrounding highway network.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

6.5.22 Where the Dilworth Lane TA considers the same junctions as the Inglewhite Road assessment the traffic flows have been directly extracted from the Inglewhite Road TA. For other junctions that were not considered within the Inglewhite Road TA, but were considered in the Dilworth Lane TA, the distribution pattern from the Dilworth Lane traffic distribution has been used to assign the Inglewhite Road traffic.

6.5.23 The resultant Inglewhite Road committed development traffic flows are shown in Figures 19 and 20.

Committed Development Summary 6.5.24 The committed development traffic flows have been added to the ‘2024 Factored’ traffic flows set out in Figures 3 and 4 with the resultant ‘2024 Base’ traffic flows shown in Figures 21 and 22.

6.5.25 It should be noted that the methodology of applying TEMPRO growth and also manually adding the committed development traffic is considered to include a significant degree of “double counting”. It is highly likely that some of the numerous committed developments are already included within the TEMPRO planning assumptions.

6.6 Proposed Development Traffic Generation

6.6.1 The trip generation of the proposed development has been discussed with LCC during scoping discussions. LCC have requested the use of trip generation rates derived from a traffic survey undertaken at College Close, Longridge on the 31/01/2013. College Close is a cul-de-sac of 47 dwellings.

6.6.2 The resultant trip generation rates and trip generation for the assessed development quanta of 220 units is set out in Table 6.2. It should be noted that the planning application is in support of a development quanta of 195 units and these figures therefore represent a ‘worst case’.

AM Peak PM Peak

Arrivals Departures Total Arrivals Departures Total

Trip Rate 0.213 0.489 0.702 0.574 0.383 0.957

Trips (220 Units) 47 108 155 126 84 210

Table 6.2 – Development Trip Rates and Trip Generation (220 units)

6.6.3 Table 6.2 demonstrates that the proposed development is anticipated to generate in the region of c. 155 two-way trips in the AM peak and 210 trips in the PM Peak. However, it should be noted that the PM Peak trip rate in particular is higher than would be expected should the trip rate be extracted from the TRICS database using a ‘typical’ Transport Assessment methodology, as suggested in the DfT Guidance on Transport Assessment.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

6.6.4 For example, the TRICS database has been interrogated to provide trip rates from equivalent English Houses Privately Owned sites ranging between 200-350 dwellings. Table 6.3 sets out a comparison of the trip generation levels using mean and 85th percentile TRICS trip rates with those supplied by LCC.

AM Peak PM Peak

Arrivals Departures Total Arrivals Departures Total

LCC Trip Rate 0.213 0.489 0.702 0.574 0.383 0.957

TRICS Mean Trip Rate 0.166 0.455 0.611 0.423 0.247 0.7

TRICS 85th Percentile Trip Rate 0.217 0.530 0.747 0.506 0.311 0.817

LCC Trips 47 108 155 126 84 210

TRICS Mean Trips 37 100 137 93 54 147

TRICS 85th Percentile Trips 48 117 165 111 68 179 Table 6.3 – Development Trip Rates and Trip Generation (220 units)

6.6.5 The comparison table demonstrates that the trip rates provided by LCC represent a robust assessment, with a higher total traffic generation than both TRICS mean and 85th percentile trip rates. By way of comparison, in the PM Peak the LCC trip rates result in 31 more two-way trips than the 85th percentile trip rates and 21 additional two-way trips when the AM and PM Peak are combined.

6.7 Proposed Development Traffic Distribution

6.7.1 A trip distribution pattern based upon SWS census data has been derived, using Dilworth as the origin ward. The distribution pattern has been agreed with LCC. A summary of the distribution and assignment pattern is included within Appendix D and the resultant turning proportions shown in Figure 23.

6.7.2 These turning proportions have been applied to the trip generation values shown in Table 6.2 and the resultant AM and PM Peak Development Traffic flows are subsequently illustrated in Figures 24 and 25.

6.7.3 The development traffic flows have been added to the ‘2024 Base’ traffic flows to form the ‘2024 Base + Development’ scenario traffic flows. The resultant figures are set out in Figures 26 and 27.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

7.0 Highway Impact

7.1 Introduction

7.1.1 The following section contains the results of capacity assessments at the site access and on the local highway network. As above, it should be noted that all capacity assessments assume a scenario of 220 dwellings, whereas the planning application is in support of proposals for 195 dwellings.

7.2 Methodology

7.2.1 Each junction was modelled using an industry-standard software package relevant to the junction type. The priority junctions were modelled using PICADY 5, roundabout junctions using ARCADY 7 and signalised junctions were modelled using LinSig 3.2. All models were constructed using Ordnance Survey mapping/topographical survey data and on-site observations. Traffic signal timing data was obtained from Lancashire County Council (TfGM) to inform all LinSig models.

7.2.2 The junction model outputs are included as Appendix E and the results are summarised below.

7.3 Interpretation of Model Results

7.3.1 ARCADY and PICADY results refer to the Ratio of Flow to Capacity (RFC) and the queue length predicted on each arm of the junction. An RFC of 1.00 indicates that the arm in question is operating at its theoretical capacity, whilst an RFC of 0.85 or less indicates that the arm is operating within its practical capacity.

7.3.2 LinSig results refer to the Degree of Saturation (DoS) and Mean Maximum Queue (MMQ) predicted in each lane of the junction. A DoS of 100% indicates that the lane in question is operating at its theoretical capacity (point of saturation), whilst a DoS of 90% or less indicates that the lane is operating within its practical capacity.

7.4 Future Year Scenarios

7.4.1 A detailed description of the traffic flows used within these assessments is set out in Section 5. To summarise, the following traffic flow scenarios are used to ascertain the existing operation of the junctions assessed and the impact of the proposed development in the future year:-

 2014 Base (Figures 1 & 2);  2024 Base (Figures 21 & 22); and  2024 Base + Development (Figures 26 & 27).

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

7.5 Site Access Modelling Results

Site Access 7.5.1 The proposed site access takes the form of a priority controlled T-junction. The proposed layout is described in detail within Section 3 and illustrated in drawing TPMA1178_011 Rev L.

7.5.2 The junction has been assessed using PICADY and the results are shown below.

AM Base 2024+Dev PM Base 2024+Dev Approach Queue Queue RFC RFC (PCU) (PCU) Site Access 0.387 1 0.298 0 Blackburn Road 0.03 0 0.091 0 Table 7.1 – Site Access: ‘Base 2024 + Development’ Scenarios (220 units)

7.5.3 The results clearly indicate that the proposed junction is predicted to comfortably accommodate the proposed development during each peak period.

7.6 Local Road Network Results

Blackburn Road/Lower Road/Preston Road 7.6.1 Blackburn Road/Lower Road/Preston Road takes the form of a 3-arm priority junction, and has been assessed using PICADY. Results for each scenario are summarised below.

Preston Road/Chapel Hill Roundabout Junction 7.6.24 The Preston Road/Chapel Hill junction takes the form of a 3-arm mini-roundabout, and has been assessed using ARCADY. Initial results for the 2014 Base scenario, modelled using geometry scaled from OS Base mapping and on-site observations of road markings are summarised below.

7.6.25 These initial modelled results indicate that queuing of approximately 16 pcu’s occur in the existing situation on the Preston Road (S) arm, during the ‘peak’ 15 minute period within the peak hour. This modelled queue length was compared against queue length observations undertaken on the day of the traffic survey, which are summarised by arm and time period in Table 7.15 below.

7.6.26 It is clear from Table 7.15 that the initial ARCADY model severely underestimates capacity of the junction, when the queue length outputs are compared against observed values. This is especially prevalent on the Preston Road (N) arm in the AM Peak and the Preston Road (S) arm in the PM Peak.

7.6.27 This junction was assessed as part of the former Ridings Depot planning application and subsequent appeal (Ref: APP/N2345/A/12/2169598). The junction was modelled as part of the above applications, with similar discrepancies between the observed and modelled capacity in the Base situation.

7.6.28 In the above instance, an approach was taken to adjust the geometry of the model so that the queue length results broadly ‘match’ the observed situation. For ‘Standard’ roundabouts this is typically undertaken using an intercept correction value, however, this function is not available for the ‘Mini- roundabout’ option.

7.6.29 On this basis and to ensure a consistent approach with other committed schemes, the geometry of the ARCADY model has been amended to reflect the observed conditions. The ‘validated’ ARCADY model results for the 2014 Base scenario are set out in Table 7.16 and the revised ‘observed and modelled’ queue length comparison in Table 7.17.

7.6.30 The revised model clearly offers a more valid comparison against existing observed queue lengths and on this basis represents a more robust model on which to test the impact of the development in the future year.

7.6.36 The future year assessment results presented in Table 7.20 demonstrate that the Longridge Rd (N) arm of the Bluebell Lane/Longridge Road junction is shown to operate close to capacity in the AM Peak 2024 Scenario, with the addition of background traffic growth and committed development. The ARCADY results illustrate an RFC of 0.95 and a corresponding queue of 14 pcu’s. With the addition of the proposed development the RFC increases to 0.98 and the queue to 22 pcu’s.

7.6.37 The results indicate that the development has a marginal impact upon capacity at the junction, with a small increase in queuing which is only evident in the busiest 15 minute period within the AM Peak hour. Furthermore, the assessment is very robust and the application of 15% background growth on all arms, plus committed development equates to several hundred vehicles, which may be an overestimation.

8.0 Grimsargh Corridor

8.1 Introduction

8.1.1 Scoping discussions with Lancashire County Council have led to a request to assess the impact of the development on the ‘Grimsargh Corridor’, which takes the form of Preston Road/Longridge Road through the village including Skew Bridge.

8.1.2 The assessment of the corridor has been undertaken in the context of the recent Former Ridings depot appeal (Ref: APP/N2345/A/12/2169598), which included a detailed assessment of the corridor as part of the Appellants submitted Proof of Evidence.

8.1.3 This evidence demonstrated the following key points in relation to the Grimsargh corridor:-

 The Grimsargh Corridor has sufficient geometric parameters to accommodate the observed and predicted traffic flow;  There are no existing Personal Injury Accident data record concerns in Grimsargh;  Preston Road is currently shown to operate within its link capacity; and  The Former Ridings depot site was shown to have a negligible impact upon levels of queuing at the Skew Bridge.

8.1.4 The Inspectors appeal decision then stated agreement with the findings of the study, with an extract from the appeal decision set out below.

Moving to look at the existing conditions on the Grimsargh route along the B6243/B6244 through to the employment areas north east of Preston and the City Centre itself, the Council advanced very limited objective evidence. The Appellants addressed the main points raised by local objectors, and my assessment of existing conditions from a number of runs made between the appeal site and Preston City Centre largely coincides with their conclusions.

8.1.5 On this basis, an assessment of the existing conditions within Grimsargh have been undertaken and equivalent analysis to that presented in the Ridings Appeal undertaken in order to assess the impact of the proposed development at Dilworth Lane upon the operation of the corridor.

8.2 Preston Road Existing Traffic Flows

8.2.1 As part of the traffic surveys described in Section 5, an ATC was implemented on Preston Road between the 19th-25th March 2014. A summary of the average weekday peak hour flows are set out below in Table 8.1.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

Direction Time Period NB SB TOT AM Peak 544 739 1284 PM Peak 782 505 1287 Table 8.1 – Preston Road 2014 ATC Results

8.2.2 These traffic flows are very similar to those recorded as part of the Ridings Depot Proof of evidence, as shown in Table 8.2 below.

Direction Time Period NB SB TOT AM Peak 499 805 1304 PM Peak 755 466 1221 Table 8.2 – Former Ridings Depot Preston Road 2012 ATC Results

8.2.3 It is therefore clear that the ATC data collected as part of the Curtins traffic surveys appear representative of existing conditions within Grimsargh.

8.3 Preston Road Link Capacity Analysis

8.3.1 An assessment of link capacity on Preston Road has been undertaken below.

8.3.2 The DfT Design Manual for Roads and Bridges (DMRB) TA 79/99 ‘Traffic Capacity of Urban Roads’ sets out the capacity of different types of urban roads. From a review of the existing conditions of Preston Road and geometric parameters it is considered that Preston Road should be classified as a UAP3 according to Table 1 within the TA 79/99 document referenced above. This matches the classification assumed within the Former Ridings Depot Proof of Evidence.

8.3.3 In terms of capacity, the one-way capacity of Preston Road is approximately 1300 vehicles, with the two way capacity at 2167. Based upon the ATC flows set out above, Preston Road is currently operating at approximately 59-60% of its capacity in the AM and PM Peak. This is summarised in Table 8.3 below.

Direction Total Scenario Time Period Capacity Capacity NB SB TOT (vehicles) AM Peak 544 739 1284 2167 59.3% 2014 Base PM Peak 782 505 1287 2167 59.4%

Table 8.3 – Preston Road Existing Link Capacity 8.3.4 This estimate of capacity corresponds with the existing values set out in the Former Ridings Depot Proof of Evidence.

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

8.3.5 In order to quantify the degree of development impact, the predicted flows along the Preston Road corridor through Grimsargh are set out in Table 8.4 below. As above, these assessments assume a scenario of 220 dwellings, whereas the planning application is in support of proposals for 195 dwellings.

Direction Time Period Scenario NB SB TOT

Proposed Development AM Peak 23 54 77 (220 Units) PM Peak 63 42 105 Table 8.4 – Preston Road Link Capacity

8.3.6 Table 8.4 demonstrates that the development could potentially increase existing flows on Preston Road between 5.9% in the AM Peak and 8.2% in the PM Peak depending on the scenario tested.

8.3.7 Taking the observed traffic flows and predicted development traffic into account, it is clear that with the development, Preston Road would operate at between 62%-65% of its capacity with the addition of the development traffic.

8.4 Skew Bridge Queue Length Analysis

8.4.1 The Ridings appeal Proof of Evidence included an assessment of the existing level of queuing at Skew Bridge, Grimsargh. Surveys conducted as part of the evidence are summarised in Table 8.5 below.

Direction Time Period NB SB AM Peak 6 5 PM Peak 8 4 Table 8.5 – Existing Skew Bridge Queue Lengths

8.4.2 Based on the comparison of ATC data collected by Curtins with the 2012 ATC data collected by the Appellant for the Ridings appeal, shown in Tables 8.1 and 8.2, it is reasonable to assume that the levels of queuing in 2014 would be similar to those observed in 2012.

8.4.3 Based on analysis of the queue lengths and traffic flows through Grimsargh, the Appellant calculated the number of additional queuing vehicles at Skew Bridge as a result of the Ridings development proposals. The Ridings traffic flows and resultant increase in queuing are summarised in Table 8.6.

8.4.5 The results demonstrate that the proposed development could result in a maximum increase of approximately 1.3 vehicles at Skew Bridge, which is comparable to the impact shown by the Former Ridings Depot.

8.4.6 On the above basis, it is therefore considered that the impact of the development upon existing queuing at Skew Bridge is likely to be minor and would not be perceptible to existing road users at Skew Bridge.

8.5 Summary

8.5.1 In summary, the impact of the proposed development at Dilworth Lane upon the operation of the Grimsargh corridor has been assessed in the context of the recent Former Ridings Depot appeal decision.

8.5.2 The analysis showed the following:-

 Existing traffic flows on Preston Road are shown to be similar to those collected as part of the Ridings Appeal;

 Existing link capacity levels are shown to be at between 59-60% of capacity; and

 Queue analysis at Skew Bridge revealed that the proposed development may increase levels of queuing between 0.6 – 1.6 vehicles at Skew Bridge.

8.5.3 The analysis mirrors the results within the Ridings Proof of Evidence, which was considered to be acceptable by the Secretary of State.

9.0 Strategic Road Network (SRN) Junctions

9.1 Introduction

9.1.1 During scoping discussions with the Highways Agency it was agreed that capacity assessments would be undertaken at two junctions on the Strategic Road Network. The M6 Junction 31a comprises two signalised roundabout junctions, the M6 On-Slip/Bluebell Lane and the M6 Off-Slip/Longsands Lane/Fulwood Road.

9.1.2 As above, it should be noted that all capacity assessments assume a scenario of 220 dwellings, whereas the planning application is in support of proposals for 195 dwellings.

9.2 Percentage Impact Assessment

9.2.1 Capacity assessments have been undertaken and these are described in further detail below. In addition, a percentage impact analysis has been undertaken in order to demonstrate the overall small proportion of overall traffic flow at the two junctions.

AM Peak PM Peak Junction 2024 Base Dev Flow % Impact 2024 Base Dev Flow % Impact

M6 On-Slip/Bluebell Lane 3302 25 0.8% 3580 34 0.95%

M6 Off-Slip/Longsands 3353 8 0.24% 3008 21 0.7% Lane/Fulwood Road Table 9.1 – Strategic Road Network: Percentage Impact Assessment (220 units)

9.2.2 The analysis in Table 9.1 demonstrates that the development has a less that 1% impact on total traffic flow at both junctions across all scenarios.

9.2.3 On this basis it is clear that the development will have a very minor impact upon operation of the junction in percentage terms.

9.2.4 It should be noted that the trip rates used within this Transport Assessment have been provided by LCC and represent a very robust assessment when compared to peak hour trip rates from TRICS. Should mean trip rates from the TRICS analysis be adopted it would result in a level of two way trips at the junctions of less than 30, which would not trigger the requirement for an assessment, as set out in the DfT document Guidance on Transport Assessments.

9.3 Capacity Assessments

9.3.1 Notwithstanding the above, capacity assessments for the above two junctions have been undertaken and a summary of the results is set out below. The full outputs are contained in Appendix F.

9.3.4 The results shown in Table 9.4 clearly indicate that some lanes are predicted to operate close to capacity in the AM Peak period and over capacity in PM Peak both ‘with’ and ‘without’ the development.

9.3.5 In the AM Peak the impact of the development is minor, with a maximum increase in queuing of 6 pcu’s observed on the Bluebell Lane ahead lane.

9.3.6 In the PM Peak the results demonstrate a maximum increase in queuing of 8 pcu’s on the same link. In the context of the junctions existing operation, an increase of this magnitude is considered minor and would not be perceptible to most road users at the junction.

9.3.7 In terms of the Practical Reserve Capacity at the junction, the results demonstrate that in terms of overall performance this indicator shows small percentage point changes of 1.2% in the AM and PM Peak periods respectively.

9.3.8 The above future year assessments have been undertaken using a ‘worst case’ set of assumptions with NTM growth factors applied in addition to traffic flows associated with several committed developments. On this basis it is expected that this would result in an element of double counting.

9.3.9 The NTM growth factors adopted for assessment in this location are approximately 15% and this is applied to all movements at the junction. A 15% increase on top of existing committed development traffic flows is considered to represent a highly robust method of assessment.

9.3.10 The results presented above can therefore be considered to represent a robust assessment of the operation of the junction in the future year.

9.4 Summary

9.4.1 In summary, capacity analysis on the Strategic Road Network demonstrates that the development has a minor impact upon the operation of the junctions in the future year, with a total development impact of less than 1%.

9.4.2 The existing conditions at the junctions above should also be considered within the context of the Broughton Corridor to the north of the M6 Junction 31a. This route provides an alternative route to Preston from Longridge and currently experiences congestion and delay.

9.4.3 The Highways and Transport Masterplan for Central Lancashire is the County Council’s vision for developing the transport network in Central Lancashire. As part of this Transport Masterplan the Broughton Bypass and improvements to the M55 Junction 1 are likely to improve this route to Preston and potentially result in increased route choice for drivers from the east approaching Preston. This may also have a positive benefit on conditions at the M6 Junction 31a.

10.0 Summary and Conclusions

10.1 Summary

10.1.1 This report considers the traffic and transport implications associated with a proposed residential development of up to 195 dwellings on a site at Dilworth Lane, Longridge.

10.1.2 A previous version of this report was originally prepared in support of an outline planning application (LPA ref. 3/2014/0517) that was submitted to Ribble Valley Borough Council (RVBC) in June 2014. The application was made for the development of up to 220 dwellings with all matters reserved, save for access from the adopted highway at land to the north of Dilworth Lane, Longridge.

10.1.3 Following a recommendation for approval by Planning Officers at RVBC, the application for 220 dwellings was heard at RVBCs Planning and Development Committee on 13 November 2014. Members voted in favour of refusing the application on the grounds that the proposed development would have unacceptable landscape and visual impact implications.

10.1.4 Taylor Wimpey have revised the scheme by reducing the number of residential units to be delivered to 195 dwellings, increasing the depth of the landscape buffers that surround the site and limiting heights to 2 storeys. The proposed site area has not altered between the previous application and the revised scheme and all other aspects of the proposal remain unchanged.

10.1.5 It should be noted that the analysis within the report still relates to 220 dwellings. It was considered unnecessary to update the analysis to reflect the reduction in dwellings proposed, as it represents a scenario which would have a greater, not lesser impact. Therefore, in concluding that the development of the site for 220 dwellings would be acceptable, it can be concluded with even greater confidence that 195 dwellings would be acceptable.

10.1.6 The report has been prepared following consultation with Highways Officers at LCC, the Highways Agency and members of the public at a consultation event.

10.1.7 A review of accident data in the vicinity of the site does not suggest an unusual highway safety problem that would be exacerbated by the proposed development.

10.1.8 Vehicular access to the proposed development will be taken from Blackburn Road via a new priority controlled junction. An emergency access will be provided onto Dilworth Lane at the western part of the site.

10.1.9 New pedestrian infrastructure is proposed in the form of a new east/west footway through the site to the rear of the existing hedgerow. This route will provide a connection to existing infrastructure which

TPMA1178/TA Dilworth Lane, Longridge Transport Assessment

in turn provides connections to Longridge town centre. A pedestrian crossing is also proposed at the eastern part of the site to satisfy a desire line to Lower Lane.

10.1.10 The site’s location adjacent to Longridge town centre ensures that there are a variety of existing facilities which are easily accessible via existing walking, cycling, and public transport infrastructure.

10.1.11 The site is well served by public transport with 4 school bus services and 6 commercial services operating within a reasonable walking distance. Two new bus stops at the eastern part of the site will further enhance public transport as a realistic mode of travel.

10.1.12 The traffic impact of the development proposals has been considered in detail and is summarised below:

 The proposed site access can comfortably accommodate the proposed development;

 Analysis of nine junctions on the LCC Local Road Network revealed that the proposed development has a minor impact in terms of junction capacity and all junctions assessed will continue to operate within capacity;

 Link capacity on Preston Road and queue length analysis at Skew Bridge has demonstrated that the development has a relatively minor impact upon existing highway conditions within Grimsargh; and

 Capacity analysis on the Strategic Road Network demonstrates that the development has a minor impact upon the operation of the junctions in the future year, with a total development impact of less than 1%.

10.2 Conclusion

10.2.1 This Transport Assessment demonstrates that the site is located in a sustainable area with well- established local facilities in accordance with national and local policy.

10.2.2 The TA also demonstrates that the highway impact associated with the proposals is not severe and therefore in accordance with national policy there are no traffic and transportation reasons why the development proposals should not be granted planning approval.
