HCPL will work with the driftconstruction contractors to use car pooling and/or mini-bus shuttles to keep light vehicle movementsassociated with drift construction to a minimum.5.2 INTERSECTION PERFORMANCEIntersection traffic flow data was collected at six relevant intersections in 2007 between 7.00 am and9.00 am, and 4.00 pm and 6.00 pm (Masson Wilson Twiney, 2008). The intersection survey locationsare provided in Appendix A (Figures A2 and A3).The performance of these intersections was assessed using the intersection analysis computerprogram SIDRA (Signalised and Unsignalised Intersection Design and Research Aid) (Masson WilsonTwiney, 2008). The results of the intersection turning movement surveys indicate that the peak trafficactivity periods in the morning and evening on the surrounding road system occurred between 8.00 amand 9.00 am, and 5.00 pm and 6.00 pm and the existing levels of service were good and with sparecapacity (Table 3) (Masson Wilson Twiney, 2008).Metropolitan Mine – Traffic Management PlanRevision No. TMP-R01-D Page 11Document ID: Traffic Management Plan
