The Council’s preferred route to/from <strong>the</strong> spine road of <strong>the</strong> study area <strong>for</strong> abnormal loads is Malaya Drive. From Malaya Drive <strong>the</strong>re is a northbound route via Bath Street and Waverdale Drive, <strong>the</strong>n ei<strong>the</strong>r west via <strong>the</strong> A187 Fossway or east via Neptune Road. Notwithstanding <strong>the</strong> desire to reduce heavy vehicle traffic on Walker Road and thus facilitate <strong>the</strong> regeneration of active frontages, it appears that it will be inappropriate to re-route all heavy traffic on Fossway, as this will require substantial physical alterations to <strong>the</strong> carriageway and dramatically change <strong>the</strong> nature of that corridor. 6.3 Local Transport and Movement Audit This section details <strong>the</strong> existing highways infrastructure, public transport and cycle provision. 6.3.1 Existing highways infrastructure The study area is mainly served by a single north-south spine route consisting of Wincomblee Road/White Street/Fisher Street which is accessed from <strong>the</strong> A186 (currently a major arterial route) at four points. The entire study area is subject to a 30mph speed limit. A186 The A186 Walker Road/Station Road/Bath Street is a 10.5 metre wide single carriageway road carrying some 11,000 vehicles per day. Along Station Road traffic flow is interrupted due to on-street parking, and a high number of junctions. Fur<strong>the</strong>r north along Bath Street, <strong>the</strong>re is less interruption to traffic flow. The A186 <strong>for</strong>ms priority junctions with Malaya Drive and Station Road, both of which have good visibility and adequate geometry to accommodate HGVs. Both also have right-turn ghost islands, although <strong>the</strong> one at Malaya Drive is narrow. At Welbeck Road <strong>the</strong> main road <strong>for</strong>ms a four-arm roundabout, with a small, kerbed central island, that is built to minimum design standards in terms of inscribed circle diameter and central island and has poor deflection in all directions. Internal study area The highway infrastructure in <strong>the</strong> area to <strong>the</strong> south of, and including, Malaya Drive is generally better than in <strong>the</strong> remainder of <strong>the</strong> study area, a reflection of <strong>the</strong> improvements already carried out <strong>the</strong>re. The carriageways and footways are in good condition, and <strong>the</strong> junctions appear to operate satisfactorily. However, <strong>the</strong> route to <strong>the</strong> Walker Public Quay is convoluted due, in part, to <strong>the</strong> steep topography of <strong>the</strong> area. A new link from this point north, perhaps through to Stai<strong>the</strong>s Street, would significantly improve accessibility to this area. Additionally, <strong>the</strong> straight road alignments encourages high speeds, and footways are present on <strong>the</strong> east side only of both Wincomblee Road and Nelson Road. The pedestrian link between Wincomblee Road and Nelson Road, via steps, is in need of maintenance, having overgrown vegetation, litter and broken street lighting. Fur<strong>the</strong>r, <strong>the</strong>re may be operational problems at <strong>the</strong> nor<strong>the</strong>rn end of Nelson Road/Swan Road when HGVs are off-loading. Malaya Drive has footway provision on <strong>the</strong> sou<strong>the</strong>rn side only. North of Malaya Drive, Wincomblee Road narrows in width to around 5.5 metres in places, with footways on both sides of sub-standard width. The access junction to riverside frontages off Wincomblee Road, located approximately 85 metres south of <strong>the</strong> junction with White Street is currently an un-marked priority junction of very poor standard. The junction has poor visibility and a constrained geometry which creates operational difficulties. HGVs were observed struggling to negotiate <strong>the</strong> junction and significantly affecting o<strong>the</strong>r traffic when doing so. A left-turn out of <strong>the</strong> junction would be difficult <strong>for</strong> cars and not possible <strong>for</strong> HGVs due to <strong>the</strong> junction layout. The steep topography in <strong>the</strong> vicinity of <strong>the</strong> junction means that improvements would be difficult. The junction of Wincomblee Road and White Street is priority controlled. Swept path analysis at <strong>the</strong> junction indicates that a FTA design articulated vehicle would have to encroach significantly onto opposing traffic lanes when turning at <strong>the</strong> junction. White Street has a relatively straight, wide carriageway and wide footways on both sides, with relatively few frontages and junctions, with <strong>the</strong> potential <strong>for</strong> high traffic speeds. Stai<strong>the</strong>s Street provides access to riverside frontages, but currently has tight radii at three bends in <strong>the</strong> road, partly a result of <strong>the</strong> steep topography. The footways are in very poor condition. However, <strong>the</strong> road does have a good, wide priority junction with White Street, with a splitter island and <strong>the</strong>re appears to be space to improve <strong>the</strong> geometry of <strong>the</strong> road in <strong>the</strong> vicinity of <strong>the</strong> junction. The junction of White Street/Welbeck Road/Fisher Street is currently a standard roundabout, with a central island built to minimum standard. The junction has very poor deflection in <strong>the</strong> north-south direction. Anecdotal evidence suggests that large articulated HGVs are unable to per<strong>for</strong>m a u-turn at <strong>the</strong> junction. Swept path analysis confirms that a FTA design articulated vehicle would struggle to per<strong>for</strong>m a u-turn at <strong>the</strong> junction. It is not, however, immediately apparent why u-turn manoeuvres would be necessary at <strong>the</strong> junction. Welbeck Road has a very wide, straight carriageway, with wide footways on both sides. Fisher Street has a reasonably wide carriageway, which has been narrowed in <strong>the</strong> vicinity of its junction with Ambrose Place. It has a relatively steep gradient in <strong>the</strong> vicinity of Welbeck Road. High levels of frontage activity and traffic calming measures interrupt traffic flow along this road. Fur<strong>the</strong>r north, at Neptune Road, <strong>the</strong> carriageway widens eventually <strong>for</strong>ming a standard roundabout junction with Maurice Road. Traffic calming Traffic calming has been implemented along Fisher Street in <strong>the</strong> <strong>for</strong>m of a single chicane, adjacent to Abingdon Road, and a mini-roundabout at <strong>the</strong> junction with Oil Mill Road. However, <strong>the</strong> implementations appear to have limited effect. The miniroundabout has been installed with no alteration to <strong>the</strong> existing geometry of <strong>the</strong> junction and with an over-runable central island. Observations suggest that vehicles are still negotiating <strong>the</strong> junction at inappropriate speeds. Swept path analysis indicates that two FTA design articulated vehicles could pass 32 Colin Buchanan
