Mount Druitt Commuter Car ParkReview of Environmental Factorsbe removed in order to improve the sight distance at the car park entrance and toimprove safety.Intersection modelling with the car park in place predicts a minor increase in delaysand queue lengths at the Mount Street/North Parade intersection during the AM peakperiod but each approach still operates with the same LoS or better than the existingintersection. Therefore, the proposed car park is not expected to significantly impactthe traffic performance of the Mount Street/North Parade intersection.Table 6-4 shows the existing intersection performance of Jirrang Close and NorthParade and the predicted change following development of the Proposal.Table 6-4Performance of Jirrang Close/North Parade IntersectionApproach eastalong NorthParadeApproach northalong Jirrang CloseApproach westalong NorthParadePeriod AM PM AM PM AM PMDelay(s)LoSQueue(m)Without car park 6 6 12 11 6 6With car park 6 6 13 11 7 6Without car park A A A A A AWith car park A A B A A AWithout car park 23 33 3 17 39 34With car park 28 33 4 17 54 34Table 6-4 indicates that the existing intersection layout operates at a LoS A from allapproaches.The Jirrang Close/North Parade intersection is predicted to generally operate at asimilar LoS to its current level during operation of the proposed commuter car park.There is predicted to be a minor increase in delays and queue lengths at the northernJirrang Close approach and a LoS B with the car park compared to the current LoS Awithout the car park. This is due to the expected additional vehicles travelling from thenorth and east u-turning at this roundabout, which in turn would delay the vehicles onthe northern approach.This demonstrates that the proposed Mount Druitt commuter car park would not havea significant impact on the performance of Jirrang Close/North Parade intersection,even with additional vehicles u-turning to access the car park.Table 6-5 shows the existing intersection performance of Sherbrooke Street and NorthParade and the predicted change following development of the Proposal.KMH-2010123a REF Rev 4 doc Page 49 of 116Status: Final
