Vehicles arrive in a single approach for two consecutive cycles at a signalized intersection. The signal has a 60 second cycle time which consists of a 30 second green interval and a 30 second red interval (ignore yellow interval). The arrival rates are assumed to be constant in both cycles. The arrival rate was 1,080 vehicles/hour in the first cycle and it decreased to 720 vehicles/hour in the second cycle. Assume that all vehicles in the queue formed on red...

An approach to a signalized intersection has a saturation flow rate of 1800 veh/h. At the beginning of an effective red, there are 6 vehicles in queue and vehicles arrive at 900 veh/h. The signal has a 60-second cycle with 25 seconds of effective red. What is the total vehicle delay after one cycle? What is the maximum length of queuing within this cycle? (assumeD/D/1 queuing)
