Vehicles arrive to the park entrance at a constant rate of 900 veh/hour from
7:30 AM to 8:10 AM and then at a constant rate of 600 veh/hour from 8:10 A.M.
The park opens at 8:10 A.M. and the manager wants to set the departure rate so that the average delay per vehicle (i.e.:
Total delay/total number of arrival) is no greater than 24 minutes (measured from the time of the first arrival until the total queue clears).
Assuming D/D/1 queuing, what is the minimum departure rate (?) needed to achieve this?
What is the total delay at this rate?
What is the longest Queue?
Through the Walla Walla Road to the entrance of the E-1 parking lot at the University of Washington, vehicles begin to
arrive from 7:40 A.M. at a uniform deterministic rate of 480 vph until 8:20 A.M. and from then on at 120 vph. It takes 10
seconds for a vehicle to go through the paying process at the gate. If the parking lot is open at 8:00 A.M., determine
(a) when the queue will dissipate, (b) the total delay, (c) the average delay, (d) the maximum queue length (in vehicles),
and (e) the longest vehicle delay under FIFO. Show your results graphically.
[Hint: D/D/1 analysis]
