An arrival rate of 900 veh/h arrive at a single lane signalized approach that is controlled by a traffic signal that operates at a cycle

An arrival rate of 900 veh/h arrive at a single lane signalized approach that is controlled by a traffic signal that operates at a cycle length of 60 seconds and a 50:50 phase split. The yellow plus all-red interval is 4 seconds long. The unopposed saturation flow rate was measured to be 1720 veh/h/lane with a start-loss of 2 s and end gain of 3 s. Assuming an analysis period of 1 hour and the traffic signal turns red at time zero, do the following:

1. Compute the approach capacity.

2. Compute the maximum queue size in vehicles.

3. Compute the duration of time that the queue is being served for a typical cycle

4. Compute the average uniform vehicle delay

5.Compute the average over-saturation vehicle delay

6.Compute the average total vehicle delay (uniform plus over-saturation)

7.Compute the percentage of vehicle arrivals that come to at least one complete stop.

8.What minimum phase split is required to ensure there is no oversaturation delay?
