A signalized intersection approach with a demand volume of 800 veh/h operates at an effective ratio of 1.05 for a peak 30-minute period each evening. If the approach has a g/C ratio of 0.60 and the cycle length is 75 seconds:

What is the average control delay for the entire 30-minute period? (Hint: should be in the range of 30 seconds/veh)

What is the average control delay during the first 5 minutes of the peak period? (Hint: should be in the range of 20 seconds/veh.)

For both part A and part B, calculate Webster’s uniform delay and add to it Akcelik’s oversaturation delay.
