Wembley Sports Park Integrated Access, Traffic and Car Parking Plan

AECOMWembley Sports Park Integrated Access, Traffic and Car Parking Plan26Figure 15The Alderbury Street approach remains largely unchanged with the exception of the addition of a newsignalised pedestrian crossing across Alderbury Street.A 120m long right turn pocket is proposed for the southern approach. The length has been optimised toprovide reasonable storage for traffic to the Wembley Sports Park whilst limiting its impact on existingservices and trees in the median.To enhance pedestrian and cycle safety along Selby Street, a signalised left turn short lane is proposedon the east approach (from the Wembley Sports Park). Additionally, the lane is proposed to be asignalised slip to enable pedestrians and cyclists to continue north or south along the Selby Street PSPwhile traffic from the Wembley Sports Park is being serviced. (Note that the graphic below does notshow the pedestrian crossing north-south across the slip lane due to limitations of the software. In realitythere will be a continuous path for pedestrian and cyclists).Two right turn lanes are proposed on the east approach to reduce the green time required to serviceright-out vehicles and to minimise the delays for through traffic on Selby Street.A 35m long left turn pocket is proposed on the northern approach. The pocket length has beenconstrained by existing power poles. The left turn pocket gives the ability to service left turners into thesite.Significantly, no east-west through movements are provided for in the design to preserve the currentresidential conditions along Alderbury Street. Traffic from the east and from the west will be serviced intwo separate phases in the operations of the traffic signal. This will also assist in accommodating thetimeliness of those bus services operating along Alderbury Street (delays were recorded at over 10minutes exiting Alderbury Street on Saturday, 6 August 2011).Due to demand fluctuations, it is proposed that all vehicle and pedestrian phases, except that for thethrough vehicle phase on Selby Street, be operated on demand only. This will maximise the green timefor traffic on Selby Street whilst minimising stoppages and delays.Indicative layout for new signalised intersection at Selby Street and Alderbury Street.T:\60218676 - Wembley PK TA\8 Issued Docs\8.1 Reports\Comprehensive Integrated Access RevF.docxRevision F - 8 February 2012
