MAJ Below are the flow-saturation ratios of each movement group of a two-phase signal at a t-intersection where the eastbound and westbound traffic share a phase and then the northbound traffic has its own phase. Given each phase has a yellow time of 3 sec and all red time (red clearance) 1 sec. answer the following. Phase A East/Westbound Traffic Eastbound Shared Through Right 0.41 seconds Westbound Left Through seconds 0.27 0.38 Phase B Northbound Traffic Northbound Left 0.33 Right • Determine the optimal cycle length using Webster's method. 0.30 . If the cycle length was 55 seconds, determine the effective green time for Phase A.
