For an arrival flow of 750 veh/h at a one-lane approach to a signalized intersection

and a signal cycle of 80 sec, derive a

conservative

estimate of the average queue

reach. If the probability of the queue reaching an intersection 120 meters away is

more than 0.05 then the situation is deemed undesirable. Determine whether or not

this is the case.

    The saturation flow rate for an intersection approach is 3600 veh/h. At the beginning of a cycle (effective red) no vehicles are queued. The signal is timed so that when the queue (from the continuously arriving vehicles) is 13 vehicles long, the effective green begins. If the queue dissipates 8 seconds before the end of the cycle and the cycle length is 60 seconds, what is the arrival rate, assuming D/D/1 queuing? Draw D/D/1 queuing diagram and label accordingly ??...
