A signal approach has 20 seconds of displayed green, 4 seconds of yellow, and 3 seconds of all red (assume typical start-up, lost time, and clearance time). The cycle length is 60 seconds. At the beginning of an effective red there are no vehicles in queue and vehicles arrive at three-quarters of the saturation flow rate for 30 seconds. Then there is zero flow for 10 seconds, and then one-half of the saturation rate from 40 seconds until the end of the cycle. What is the total delay for this cycle if the saturation flow rate is 1400 veh/h (in veh-s)? Assume D/D/1 queuing.
