Q7.6 Calculate the minimum cycle length and the effective green time for each phase (balancing v/c for the critical lane groups). Assume the lost time is 4 seconds per phase

and a critical intersection v/c of 0.90 is desire Solution: An approach to a pre timed signal has 25 seconds of effective green in a 60-second cycle. The approach volume is500 veh/h and the saturation flow rate is 1400 veh/h. Calculate the average vehicle delay assuming D/D/1 queuing.
