Metropolitan Mine – Traffic Management Plan7 PERFORMANCE INDICATORSConsistent with Condition 2, Schedule 7 of the Project Approval, Table 4 outlines the performanceindicators that will be used to assess the performance of the TMP.Table 4Performance IndicatorsAspectRoad MaintenanceContributionsProduct Coal TruckingTonnagesHaulage ContractorManagementPerformance IndicatorWhen annual road maintenance contribution negotiations are required, thenegotiations should commence with the relevant councils and/or DoP by31 August.Annual road maintenance contributions to relevant councils are made by30 November.Coal transported off-site by road in a calendar year does not reach100,000 tonnes prior to 31 October.Coal and coal reject haulage trucking contractors will be notified of HCPL’s offsitehaulage requirements by 31 October 2010.Monitoring that will be conducted to assess the performance indicators is described in Section 9.8 TRAFFIC MANAGEMENT8.1 ROAD SAFETY AUDIT OF PARKES STREET AND MINE ACCESS ROAD INTERSECTIONIn accordance with Condition 17, Schedule 4 of the Project Approval a Road Safety Audit of the MineAccess Road and Parkes Street intersection (Figure 4) was conducted in September 2010. The roadsafety audit considered the following aspects:• intersection layout and geometric design;• vehicle/vehicle conflicts;• vehicle/pedestrian conflicts; and• lighting, signs, delineation and drainage.The recommendations of the audit will be implemented to the satisfaction of the Director-General of theDoP once the Road Safety Audit and Recommendations Report is finalised in consultation with theWCC and RTA.8.1.1 Potential Intersection ImprovementsA number of potential intersection improvement options have been identified through the initialconsultation, site inspections and the conduct of the road safety audit (Table 5). The implementation ofthese measures will be described in future revisions of the TMP.Metropolitan Mine – Traffic Management PlanRevision No. TMP-R01-D Page 16Document ID: Traffic Management Plan
Metropolitan Mine – Traffic Management PlanTable 5Potential Intersection ImprovementsIntersectionAspectVisibility –Parkes StreetVisibility – MineAccess RoadSignage –Parkes StreetSignage – MineAccess RoadVerticalAlignment –Parkes StreetPedestrians –Parkes StreetDescription of IssueVisibility on the northbound approach to theintersection is restricted by a 60° left hand bend.This may lead to road users being unaware oftrucks from the Mine Access Road turning ontoParkes Street.The hold line and stop sign on approach to ParkesStreet are set back 10 metres (m) from the kerbline.This reduces the visibility to the right toapproximately 30 m for vehicles waiting to exit theMine Access Road, which may lead to vehicleconflicts due to vehicles exiting Mine Access Roadnot sighting oncoming traffic.The commencement of the existing 40 kilometreper hour (kph) school zone coincides with theMine Access Road intersection.This may distract or confuse road users and leadto conflicts due to late decision making.There are multiple signs mounted together at theintersection including:- Mine Entrance.- Caution Trucks Turning.- Five right turn arrows.- Community call line and telephone number.- Peabody Australia/Metropolitan Mine.As these signs are nonstandard, they may lead toconflicts and confusion due to late decisionmaking.The northbound approach to the intersection is onan approximate 10% down grade.This may encourage excessive speeds onapproach to the intersection and lead to conflictswith vehicles waiting to turn right into theintersection.The existing crossing adjacent to McMillan Streetis uncontrolled.This crossing is likely to have high usage at peaktimes and may lead to pedestrians crossing theroad at other points due to the waiting times at thecrossing, which may lead to vehicle/pedestrianconflicts.Potential ImprovementProvide junction and “Trucks Turning”warning signs on approach to the bendand chevron signs to warn drivers of theapproaching road layout.Provide an offset edge line pavementmarking on the inside of the bend todiscourage drivers cutting the corner andimprove visibility.Consider installing a flashing light unitcontrolled by detectors on the MineAccess Road’s exit lane in addition tothe junction warning signs.Relocate the hold line and stop sign tobe in line with the proposed kerb andgutter.Relocate the commencement of the40 kph school zone to the south, inadvance of the left hand bend.Replace existing Mine Entrance sign withstandard guide sign.Relocate mine information sign awayfrom the intersection.Provide a “Steep Descent” warning signand a “Reduce Speed Now” sign onapproach.Replace with a controlled zebra crossingto encourage pedestrians to cross at asingle point and remove all conflictingcrossing warning signs.Metropolitan Mine – Traffic Management PlanRevision No. TMP-R01-D Page 17Document ID: Traffic Management Plan
