5. The metering scheme of a ramp meter installed along the Pampanga Subic Expressway allows one vehicle to pass the signal. The cumulative demand for the ramp for the morning peak and ramp meter cycle for each interval are shown in the table. Determine the following: Time Period ib min Cumulative Meter Cycle volume Volume 6:30 - 6:45 75 75 6 6:45 - 7:00 100 175 10 7:00 - 7:15 125 300 12 7:15-7:30 110 410 12 7:30 - 7:45 80 490 10 7:45 - 8:00 65 555
2. [-/8 Points] For a peak hour volume of 840 vehicles, within which the peak 15-minute volume is 244 vehicles, the PHF is: 0.86 0.29 3.44 O 1.00 DETAILS 1.13 MY NOTES ASK YOUR TEACHER
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]
