Mount Druitt Commuter Car ParkReview of Environmental FactorsThe impact of heavy construction vehicles on local roads in addition to theconstruction workforce would require the implementation of traffic managementmeasures.On North Parade 14 on-street parking spaces would be reserved for heavy vehiclesduring construction. The reserved spaces are proposed to be removed to allow for theproposed car park entrance and exit. Additional parking would be required forconstruction workers in proximity to the site which would have a minor temporaryimpact on available commuter parking in the area.The reconfiguration of the car park at the North Parade entrance to Mount DruittRailway Station would also impact on ten spaces, including three disabled car parkingspaces. Table 7-1 includes mitigation measures to address this impact.The movement of construction vehicles would need to take account of pedestriansusing the footpath along North Parade. Surrounding the construction site are severalcommercial and community facilities including schools and a hospital, all of whichgenerate large pedestrian volumes accessing Mount Druitt Railway Station. It has alsobeen observed that these pedestrians cross North Parade in front of the site, oftenjaywalking and utilising the median as a refuge. The Construction Traffic ManagementPlan would include measures to ensure safe pedestrian movements around theconstruction site. Measures such as pedestrian detours and/or traffic controllers maybe needed to ensure conflict between construction traffic and pedestrians areminimised.No public transport facilities would be impacted during construction. Slight delays mayoccur when construction vehicles are turning to enter the construction site however,construction works would be short-term in duration.Operational stageIntersection performanceThis section focuses on the potential traffic, transportation and access impacts thatmay arise from the operation of the proposed commuter car park at Mount Druitt.Computer modelling of intersection performance both pre and post-development wasundertaken using the computer modelling package SIDRA. Outcomes of the modellingare summarised in this section. Further detail of the modelling is provided in the Trafficand Transport Impact Assessment (refer Appendix C).The key intersections potentially affected by operation of the Proposal are illustrated inFigure 6-2 and listed below:North Parade Site Entrance/North Parade;North Parade/Mount Street;North Parade/Jirrang Close;North Parade/Sherbrooke Street; andLuxford Road/Mount Street.The peak hour periods on the local road network would occur between 0800-0900and 1630-1730. The peak hour periods for commuters entering and exiting theproposed car park would occur between 0700-0800 and 1800-1900.In reality, the local road network peak and the commuters arriving and departing peakwould not coincide. However, to assess the potential ‗worst case scenario‘ the peakhour arrival/departure volumes for the car park were modelled on top of the local roadnetwork peak hour volumes.KMH-2010123a REF Rev 4 doc Page 47 of 116Status: Final
