Sub-problem 2b: Analyzing the Effects of Signal Phasing

The eastbound left delay went from 219 sec/veh to 21 sec/veh while maintaining reasonable performance levels for other movements. The westbound movements were slightly improved (LOS C to B) with some deterioration for southbound movements (LOS C to D/E). The overall intersection improved from a delay of 77 sec/veh (LOS E) to a delay of under 22 sec/veh (LOS C). These results suggest that the added phase offer an overall improvement to the operation of the intersection at a level that warrants its implementation.
