A signal approach has 20 seconds of displayed green, 4 seconds of yellow, and 3 seconds of all-red intervals. The total lost time per cycle is 4 seconds. At the beginning of the effective red interval, there are no vehicles in the queue, and vehicles arrive for 30 seconds at three-quarters of the saturation flow rate. Then there is zero flow for the next 10 seconds, and then one-half of the saturation flow rate from 40 seconds until the end of the cycle. What is the approach's total delay for this cycle if the saturation flow rate is 1400 veh/h? Fractional vehicles for intermediate calculations are permissible (round up your intermediate calculations to two decimal places).
