INTRODUCTION Roughan & O’Donovan (ROD) was commissioned by Cairn Homes Properties Ltd. to undertake a Traffic and Transport Assessment for a proposed residential development, located off the R761 Kilcoole Road and north of the Eden Gate Housing Development. 2. STUDY METHODOLOGY This Traffic and Transport Assessment (TTA) has been prepared to assess the traffic and transportation impacts of the proposed residential development. It has been carried out in line with the ‘Traffic and Transport Assessment Guidelines’ published by TII (NRA) and ‘Guidelines for Transport Impact Assessment’ published by the Institution of Highways and Transportation (IHT). 3. THE EXISTING RECEIVING ENVIRONMENT (BASELINE SITUATION) 3.1 Site location The site location of the proposed development will be in Farrankelly, Co. Wicklow, as shown below in Figure 1 Site Location Map. The site is approximately 15.6 ha in area and is bounded by the R761 Kilcoole Road to the East, Eden Gate housing estate to the south, Priory Road to the west and Delgany Glen housing estate and undeveloped lands to the north. Figure 1 – Site Location Map 3.2 Surrounding Road Network 3.2.1 R761 Kilcoole Road The R761 Kilcoole Road is a regional road that extends approximately 23.5 km linking Bray to Rathnew. In the vicinity of the site Kilcoole Road extends between the roundabout at the R774 Farrankelly Road and the roundabout at the R762 Mill Road, over a total length of approximately 1.3 km, see Figure 2. 16.146 Page 1 ROUGHAN & O'DONOVAN Cairn Homes Consulting Engineers Farrankelly Residential Development Figure 2 – Location Map Surrounding Road Network Site Location © OpenStreetMaps Figure 3 – Kilcoole Road - end of the footpath provision on the western side of the road approaching Three Trouts Bridge 16.146 Page 2 ROUGHAN & O'DONOVAN Cairn Homes Consulting Engineers Farrankelly Residential Development The section of Kilcoole Road is a two-lane regional road with a posted speed limit of 50 km/h. The carriageway road has a variable width between 6.2m and 7.2. There is a continuous footpath on the east side of the road but there is no footpath on the west side past the site, see Figure 3. A signalised pedestrian crossing is provided on the R761 approximately 150m north of the roundabout junction with the R774 Farrankelly Road dual carriageway to the west of the site. This facility accommodates pedestrian access to Glenbrook Park and Eden Gate and provides a link between bus stops on each side of the road. A cycle track has been constructed on the eastern side of the road, along the boundary of the Glenheron development, which connects to the Farrankelly Road. There are no facilities for cyclists along the Kilcoole Road to the north of the site entrance. On the opposite side of the road to the site there are a number of properties accesses and the entrance to Glenheron the recently completed residential development. To the north on the same side of the road is the entrance to Farrankelly House which includes a number of commercial operations. 3.2.2 Priory Road Priory Road is a single carriageway road of approximately 1.6km linking between the R744 Farrankelly Road at Eden Gate and the R762 in Delgany. The road has a variable width along the frontage of the site between 4.8m and 5m and there is no footpath in the vicinity of the site. Along the frontage of the site there are no hard shoulders or footpaths. There are a number of accesses to properties on the opposite side of the road to the site. 3.3 Existing Traffic Extensive traffic surveys were carried out in April 2016 by Abacus at several locations as part of a study that include the adjacent Glenheron residential developments by Cairn
