Unformatted text preview: within the queue diagram), to do that you have to find total time and total number of vehicles first. The time for queue to clear, t, is the time where arrival and service curves become equal at the tip of the shape: 66.7* t = 20*25 + (t
35)*80
2300 = 13.3 t
t = 172.93 min Total number of vehicles in the queue: 66.7 * 172.93 = 11,534.45 vehicles Calculate the area within the curve to obtain total delay (then you divide total delay by total number of vehicles to get the average delay), Total delay: (66.7*172.932)/2 – (25*202)/2 – ( (500+11534.45)/2 * (172.93
35)) = 162,368.77 veh
min Average delay for scenario A = 162,368.77 / 11,534.45 = 14.08 min (per vehicle) Ske...
