At 9 am, vehicles arrive at a toll booth facility at the rate of 8 vehicles/min. Initially, the toll booth is closed from 9:00 am until 9:15 am. Then it opens from 9:15 with a service rate of 10 vehicles/min. Assuming D/D/1 queuing, determine: (1) At what time queue is disappears? (2) What is the total delay? (3) What is the maximum Queue length? (4) What is the queue length at time t=30? (5) What is maximum delay? (6) What is the delay for 200th vehicle?

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...
