AECOMWembley Sports Park Integrated Access, Traffic and Car Parking PlaniiiParking ProvisionThe layout provides a total of 1,010 formed parking spaces and approximately 200m of drop-off space in Stage 1.The parking supply will reduce to 870 formed parking spaces, with no reduction in drop off space, in Stage 2.The Master Plan identifies the potential for a grassed area on the southwest corner of Wembley Sports Parkwhich could be used for further overflow parking.Overall in Stage 1 the maximum demand for car parking was calculated to be 1,021 bays which exceeds thenumber of provided bays by a handful of vehicles, however, the 85 th percentile demand of 869 vehicles can beeasily accommodated within the available hard standing parking. In the short periods where demand exceeds thecapacity of the hard standing parking the additional demand can be accommodated within the grass overspill areabetween the south-western and south-eastern car parks.In Stage 2 the peak demand for parking was estimated at 1,070 bays. This exceeds the number of formed baysavailable by 200 but aligns well with the 85 th percentile demand. On the occasion where demand is higher thansupply grassed overflow parking, with management intervention, will provide adequate parking.For Stage 2 where it is estimated the proposed parking demand will exceed supply during a few relatively shortperiods on 18 Saturdays per year, the introduction of Green Travel initiatives are recommended for the site, andshould commence immediately to reduce the impact ahead of full development of the site.Buses accessing the site will utilise the drop-off facilities to park.Traffic AnalysisVehicles exiting Wembley Sports Park at the Northern Access, wishing to turn right into Salvado Road areforecast to be caused delays with the access operating at or over capacity during the peak Winter SaturdayEvents. This congestion may cause some traffic redistribution towards the Main Access at Selby Street. Thesecongested conditions are expected to dissipate relatively quickly. This full access is recommended in order todistribute the traffic evenly and to service the traffic during the peak Winter Saturday Events more effectively.The proposed Main Access (signalised intersection) at Selby Street / Alderbury Road is forecast to operate closeto or at capacity during these peak Winter Saturday Events. Right turn queues from Selby Street are expected toexceed the available queuing space of 120m for very short periods during the peak Winter Saturday Events. Thisis considered to be acceptable and is unlikely to affect the operation of Selby Street for through traffic.The analysis also showed the AM and PM traditional weekday peaks perform better than the Winter Saturdaypeaks for a signalised intersection at Selby Street / Alderbury Road.The existing left-in access on Selby Street is expected to operate well.The existing left-out egress on Selby Street is forecast to operate well most of the time, except during theoutbound peak on Winter Saturdays. However, the delays are not expected to occur over extended periods oftime and the queues forming during these periods are also expected to dissipate relatively quickly.For safety and operational reasons, right turns cannot be allowed at the access from the East-West Link to thesouthwestern car park. These right turns can be accommodated via u-turns at the roundabout located at theeastern end of the East-West Link.At the estimated drop-off rate and under normal conditions, the proposed drop-off facilities are not expected tocause flow breakdowns on the East-West Link. Even with the induced u-turn traffic, the link is expected tooperate within capacity.The North-South Link from Salvado Road to the roundabout will provide an important circulation facility;particularly during the peak Winter Saturday Events. Flow breakdowns are expected to occur if these vehicles arechanneled directly through the Stage 1 northeastern hard stand car park. Additionally, without the southernportion of the link, traffic entering the car park from the south would not be able to make u-turns and would beforced to exit at Salvado Road. For operational flexibility and efficiency, the entire North-South Link is thereforerequired in both Stages 1 and 2.T:\60218676 - Wembley PK TA\8 Issued Docs\8.1 Reports\Comprehensive Integrated Access RevF.docxRevision F - 8 February 2012
AECOMWembley Sports Park Integrated Access, Traffic and Car Parking PlanivMitigation and ActionFor peak periods, where the parking demand may exceed the supply, measures should be implemented to reducedemand. These measures include engineering, education, encouragement and enforcement. To achieve this, aGreen Travel Plan (TravelSmart) for the PNA’s activities should be developed. This report includes suggestionsof measures that could be included in the plan. A set of traffic and people movement plans were also developedto manage the use of facilities and the movement of people during the various events.ConclusionThis transport study generally supports the approved Wembley Sports Park Development Master Plan. While thestudy identified that traffic and parking demand may exceed capacity during the peak Winter Saturday events,these events are anticipated to be relatively short and their impacts are considered to be acceptable. For the vastmajority of its operations, the Master Plan provides ample capacity and caters for the 85 th percentile of peakdemand. It is therefore considered to be unreasonable and unsustainable to provide more capacity. Rather thanproviding for all parking demands at all times, it is recognised that alternative measures are required to managethe short demand peaks on Winter Saturdays (18 competition days annually).The transport facilities for the Master Plan are illustrated in Figures 12 and 13 and are listed in therecommendations in Section 7.0 of this report.Subject to the recommendations outlined in this report, it is expected that the following traffic solutions will provideadequate access, car parking and traffic management facilities for the assumed operations of the WembleySports Park:- increased access points to the site;- new and improved internal circulation design;- increased car parking provision;- development and implementation of green travel initiatives in order to reduce vehicular parking demand; and- implementation of site and event specific traffic and people movement plans.T:\60218676 - Wembley PK TA\8 Issued Docs\8.1 Reports\Comprehensive Integrated Access RevF.docxRevision F - 8 February 2012
