An incident occurs on a freeway that has a capacity of 3,500 veh/h in the northbound direction. The arrival flow rate was of 2,500 veh/h during the morning commute. At 7:30 AM, a traffic accident occurs which closes the freeway to all traffic. At 7:42 AM, freeway is partially opened with a capacity of 1,750 veh/h. Finally, the wreckage is removed, and the freeway is restored to full capacity (3500 veh/h) at 8:01 AM. Assume D/D/1 queuing to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and the longest wait of any vehicle (assuming FIFO).

Question
An incident occurs on a freeway that has a capacity of 3,500 veh/h in the
northbound direction. The arrival flow rate was of 2,500 veh/h during the morning
commute. At 7:30 AM, a traffic accident occurs which closes the freeway to all
traffic. At 7:42 AM, freeway is partially opened with a capacity of 1,750 veh/h.
Finally, the wreckage is removed, and the freeway is restored to full capacity (3500
veh/h) at 8:01 AM. Assume D/D/1 queuing to determine time of queue dissipation,
longest queue length, total delay, average delay per vehicle, and the longest wait
of any vehicle (assuming FIFO).
