At the beginning of an effective red, vehicles are arriving at an approach at the rate a = 500 veh/h and 12 vehicles are left in the queue from the previous cycle (at the end of the previous cycle's effective green). However, due to the end of a major sporting event, the arrival rate is increasing at a constant rate of b = 200 veh/h every minute (consider uniform but different distribution every minute, i.e. arrival rate during first minutes is a veh/h, during second minutes is (a + b) veh/h, during third minutes is (a + b + b) veh/h, etc.). The saturation flow rate is uniform (deterministic) and is equal to 1600 veh/h, the cycle length is 60 seconds, and the effective green time is 43 seconds. If only deterministic delay is considered, at what level of serves this intersection is operating during every cycle until complete queue clearance.
