Traffic counts and signal timing data were collected for theintersection of Sand Creek Road and Wolf Road. The intersection issignalized. The collected data show that, for a particular cycle,vehicles on the through lane of the SB of Sand Creek Road had thefollowing arrival headway pattern (counted from the start of thered time of the cycle):
– 2.5 seconds for the first 10 seconds
– 2 seconds for the time period of 44 †50 seconds, and for thetime period of 130 †166 seconds
– No vehicle was observed inâ€between of the above timeperiods.
– Collected data also show that the cycle length is 200 secondswith 140 seconds for the effective red time and 60 seconds for theeffective green time. Assume the discharge headway after the signalturns green is 2 seconds. Ignore the interactions of vehicles fromleft†and rightâ€turn lanes when you conduct the analysis.
Find:
– Maximum queue size
– Maximum delay
– Total queuing delay
– Average queuing delay
