Mount Druitt Commuter Car ParkTraffic, Transportation and Access Impact AssessmentThe models have been calibrated to the observed queue data onsite. Any parameters thathave been changed within the model have been highlighted. The following assumptions weremade in the SIDRA models:The network peak hour volumes were modelled as the Do Minimum models;The SCATS data for the Luxford Road / Mount Street intersection was unavailable andas such, the phasing has been modelled based on site data and the signal timingsoptimised in order to produce the observed onsite queues; andThe SCATS data for the North Parade / Mount Street intersection was used to model thisintersection for the Base Model before being optimised to model the Do Minimummodel, against which the car park impacts were modelled.5.1.1. Intersection Assessment and MitigationThe intersections were assessed using the NSW RTA standards. The queue lengths andaverage approach delays were also used in our assessment. The intersections modelledwere:I. North Parade Site Entrance/ North Parade;II. Mount Street / North Parade;III. Jirrang Close / North Parade;IV. Sherbrooke Street / North Parade; andV. Luxford Street / Mount Street.It was found through our assessment that there was no need for any mitigation measures tobe carried out relating to operation or capacity of the intersections.The effects of the Mount Druitt car park on the wider network were within acceptable levelsas discussed below.I. North Parade Site Entrance/ North Parade IntersectionThe intersection modelled within SIDRA is shown in Figure 5-3.The modelling indicates that there will be no operational problems with the Mt Druitt car parkentrance with the only queue occurring during the PM Peak due to vehicles exiting the carpark. This is shown in Table 7.CCPP-0843-RW-7291-F.docx Page 25 of 46Status: Final CDR
