Subject: Summary of Transport Issues associated with Longwick Sites

This Technical Note summarises transport issues associated with the potential Longwick development sites shown in Figure 1.

Figure 1 - Potential Longwick sites

Highway Network The primary destinations around Longwick include Princes Risborough and High Wycombe to the south, Aylesbury and Leighton Buzzard to the north, and to the west and Amersham to the east. The A4129 runs through Longwick. It continues north to Thame and south to Princes Risborough town centre. The A4129 meets the B4009 at a roundabout. The B4009 Lower Icknield Way provides access to and from the south-west and to the A4010 leading to Aylesbury. The M40 can be accessed from Junction 6 at Lewknor via the B4009.

Rail Network The nearest railway station to Longwick is Princes Risborough. The Chiltern Railways line passes through Princes Risborough just south of a point where the track diverges to form a line continuing north-east to Aylesbury, a line continuing north-west towards Bicester, Warwick and Birmingham and a line to Chinnor. The Birmingham line operates with an approximately half hourly service frequency, with the Aylesbury line approximately hourly. Potential for significant journey time and accessibility benefits for the Princes Risborough area are expected to be offered through the Chiltern Railways Evergreen 3 and East West Rail projects.

Bus Network The Risborough Area Community Bus provides local transport for the local communities. One local service is Route 3 which runs between Princes Risborough High Street and Longwick Post Office / Thame Road lay- by.

Cycle Network Mapping on the website shows a cycle route running along Walnut Tree Lane and connecting with North Mill Road which connects with National Cycle Route 57; the from Princes Risborough to Thame.

Traffic generation CampbellReith has undertaken a trip generation exercise using the TRICS database and applying the following criteria:

• Multi-modal surveys in the U.K.; • Land Use 03/A, 03/B, 03/C, 03/D; • Date range: January 2006 onwards; and • Edge of Town centre / Suburban / Edge of Town locations

The Land Use criteria used are described in detail below:

03/A – Houses Privately Owned (GDO use class C3)

Housing developments where at least 75% of units are privately owned. Of the total number of units, 75% must also be houses (sum of “non-split” terraced, detached, semi-detached, bungalows, etc), with no more than 25% of the total units being flats. Includes properties that are privately owned and then privately rented. Trip rates are calculated by Site Area, Dwellings, Housing Density, or Total Bedrooms.

03/B – Affordable/Local Authority Houses (GDO use class C3)

Housing developments where at least 75% of units are non-privately owned. Of the total number of units, 75% must also be houses (sum of “non-split” terraced, detached, semi-detached, bungalows, etc), with no more than 25% of the total units being flats. “Non-privately owned” may be council rented or housing association rented/part-owned. Trip rates are calculated by Site Area, Dwellings, Housing Density, or Total Bedrooms.

03/C – Flats Privately Owned (GDO use class C3)

Housing developments where at least 75% of households are privately owned. Of the total number of units, 75% must also be flats (sum of flats in blocks and “split” houses), with no more than 25% of the total units being “non-split” houses. Includes properties that are privately owned and then privately rented. Trip rates are calculated by Site Area, Dwellings, Housing Density, or Total Bedrooms.

03/D – Affordable/Local Authority Flats (GDO use class C3)

Housing developments where at least 75% of households are non-privately owned. Of the total number of units, 75% must also be flats (sum of flats in blocks and “split” houses), with no more than 25% of the total units being “non-split” houses. “Non-privately owned” may be council rented or housing association rented/part-owned. Trip rates are calculated by Site Area, Dwellings, Housing Density, or Total Bedrooms.

Table 1 summaries the trip rates for these land use categories.

Traffic distribution A review of the journey to work data in the 2011 Census information for the Princes Risborough area reveals the majority of journey to work trips by car will travel south from Longwick. In general, all development sites will have trip generations based on the trip rates in Table 1. They will also have similar traffic distributions to each other.

Potential development site assessment The sites shown in Figure 1 have been rated using the following criteria:

• Proximity to major facilities • Access to the highway • Access to bus routes • Permeability with the village

Figure 2 shows the rating of sites based on their proximity to major local facilities. The sites are colour- coded with green being rated highest and red being rated lowest. Whilst Longwick provides some local facilities, Princes Risborough provides the wider range of local facilties. The sites have been rated based on their distance from the High Street area of Princes Risborough and also distance from the railway station with sites within 2km of these areas being marked the highest.

Figure 2 - Proximity to major local facilities

Figure 3 shows the rating of sites based on access to the highway. Sites I, J, P and Q have been rated the lowest due to access being via narrow roads or being further away from the main road. Sites M, N and O may have more issues than other sites in achieving a convenient, safe access to the highway due to the proximity of existing junctions.

Figure 3 - Access to highway

Figure 4 shows the rating of sites for access to bus routes based on distance and east of access to the existing bus stops.

Figure 5 shows the rating of sites based on permeability of the site with the existing village and how the potential sites could integrate with the existing surrounding properties and facilities.

The figure shows that, based on the criteria above, sites F, G, H, K, L, M, N and O appear to offer a better location for development. Other sites may also be suitable if developed in conjunction with neighbouring sites. For example, if site G is developed it may offer improved pedestrian access to sites I and J.

Potential Mitigation Measures Depending on the size of future development sites there may be a requirement to contribute to junction improvement schemes in the Princes Risborough area. Potentially improvements to the local bus service or upgrading of existing cycle routes would also benefit the local community.
