A toll booth on a turnpike is open from 8:00 AM until midnight. Vehicles start arriving at 7:45 AM at a uniform rate of 6 veh/min. At 8:15 AM the rate drops to 2 veh/min. If vehicles are processed at a uniform rate of 6 veh/min, determine when the queue will end, the total delay, the maximum queue length, and the longest vehicle delay

5.43 Vehicles arrive at a toll both starting at 7:00 A.M. at a rate of 1(t) = 5.1 – 0.05t [with (t) in veh/min and t in minutes after 7:00 A.M.]. The first operator processes cars at a rate of 3 veh/minute 7:00 A.M. until 7:15 A.M when the person leaves because of illness. From 7:15 A.M to 7:25 A.M, no one is at the toll booth but a...

6- At the beginning of an effective red, vehicles are arriving at an approach at the rate of 600 veh/h and 18 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 continuously increasing at a constant rate of 150 veh/h/min (after 1 minute the arrival rate will be 750 veh/h, after 2 minutes 900 veh/h, etc.)....
