Determine the optimum cycle length for the intersection with the volumes (in veh/hr) shown in the table below. The intersection is designed to have the following three phases: Phase A for left-turn movements from the EB and WB approaches; Phase B for the through and right movements from the EB and WB approaches; Phase C serving all movements for the NB and SB approaches. EB approach L T R 100 495 75 WB approach L T NB approach T L SB approach T L R R 115 550 100 66 450 105 45 400 Assume each intersection approach has 2 lanes, one for left-turning vehicles and one for through and right-turning vehicles. The saturation discharge headway is 2.10 seconds and lost time per phase is 4 sec. R 90 Determine the optimum cycle length for the intersection with the volumes (in veh/hr) shown in the table below.

Answer rating: 100% (QA)

To determine the optimum cycle length for the intersection we need to consider the volumes of traffic from each approach and calculate the total time ... View the full answer
