Mount Druitt Commuter Car ParkTraffic, Transportation and Access Impact AssessmentV. Luxford Road / Mount Street IntersectionThe intersection modelled within SIDRA is shown in Figure 5-8. Table 11 illustrates that theLuxford Road / Mount Street intersection operates within capacity, with the southernapproach operating with the worst LOS of C with the existing layout.It is predicted that the Mt Druitt car park will cause a less than minor increase in delays tothe Luxford Road / Mount Street intersection. It should be noted that the model forecasts areduction in the average delay but an increase in queue length for the southern approachduring the PM Peak. This is due to an increase in the left turning traffic being modelled,which influences the average delay due to the left turning vehicles experiencing less delaythan the right turning vehicles and as such, causing the average approach delay to reducedespite an increase in vehicles. Other than this anomaly, the intersection is predicted tohave a LOS B or better even with the Mt Druitt car park illustrating that the car park hasnegligible impacts on the operation of this intersection.The Luxford Road / Mount Street intersection was calibrated using the vehicle queue datafrom the surveys. The SIDRA queues approximately matched the observed queuesdemonstrating that the models are fit for purpose models.Figure 5–8: Luxford Road / Mount Street Intersection Lane LayoutCCPP-0843-RW-7291-F.docx Page 31 of 46Status: Final CDR
