Assume that passenger car equivalents are 1.5 for trucks (ET), 1.6 for left-turns (EL), and 1.4 for right-turns (ER), and saturation flow qs= 160 x (curb-to-curb width / # of lanes) equivalent passenger-car units per hour per lane (pcu/hr/ln). Pedestrian walk speed (PS) is 4 ft/sec, and the effective width of crosswalk (WE) is 9 ft. Given that the intergreen time is 8.0 seconds and lost time is 3.5 seconds per phase, design a 2-phase signal timing plan using the Webster’s method.

Quest... In a three-phase signal system design for a four- leg intersection, the critical flow ratios for each phase are 0.18, 0.32, and 0.22. The total loss time in each of the phases is 2 s. As per Webster's formula, find the optimal cycle length.
Subject: transportation engineering Read the question carefully and give me right solution according to the question. A signal has four phases, where the critical lane group flow ratios are 0.115, 0.204, 0.099, and 0.248. If the lost time per phase is 6 seconds and the critical intersection v/c ratio is 0.88, calculate the minimum cycle length and the phase effective green times such that the lane group v/c ratios are equal.
