Question

A turning movement count and a saturation flow study were conducted at a major intersection on an expressway with configuration as presented in Fig.1. The peak-hour volumes and saturation flows obtained from the studies for each movement are presented in Tables 1 and 2, respectively.

i) provide a diagrammatic representation of the signal sequence at the intersection. Assume a yellow interval of 3s, all-red interval of 2s and a peak hour factor of 0.95 for all the approaches.

Note: No two movements should conflict during the determination of the phasing plan.
