A traffic signal has a 90-second cycle length. For the travel direction of interest, the red and green times are 30 seconds and 60 seconds, respectively, the arrival rate is constant at 30 veh/min and the saturation flow (i.e., the queue discharge rate) is 1 veh/sec.Calculate the total delay [veh.s] for the travel direction of interest. What is the maximum queue size [veh]?

A traffic signal operates with a 60 seconds cycle length. On the Eastbound approach, traffic arrives at a constant rate of 20 vehicles/minute. The saturation flow is 1 vehicle/second. The effective green time is 30 seconds. Calculate the following: a. The degree of saturation (v/c ratio) b. The capacity on the approach c. The spare capacity (%) d. The average delay to all vehicles

At the signalized intersection, the vehicles began to arrive from 7:00 am (beginning of the traffic study) at the rate of 6 veh/min for 20 minutes, and declined to 1 veh/min. The traffic signal is assumed to have an effective red and green only starting from red at 7:00 am. The length of the effective green is 4 minutes and effective red time is 3 minutes per cycle. The discharge rate of the vehicles on effective green is 6 veh/minute....

1. On one approach of an intersection with fixed time traffic signal, vehicles arrival rate is 600 vehicles per hour. The effective green time for this approach is 30 seconds, the saturation flow of this approach is 1800 vehicles per hour and the cycle time of the intersection is 80 seconds. a. Evaluate the performance of the signal design i.e. will all vehicles clear during the green time? b. Recommend the changes to the green time for this approach to...

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)

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 isolated pretimed signalized intersection has an approach with a traffic flow rate of 750 veh/h and a saturation flow rate of 3200 veh/h. This approach is allocated 32 seconds of effective green time. The cycle length is 100 seconds. Determine the average approach delay (using Eq. 7.27). A) 34.8 s B) 30.2 s (incorrect) C) 35.0 s D) 4.6 s
