Traffic data are collected in 60-second intervals at a specific highway location as shown in the Table. Assuming the traffic arrivals are Poisson distributed and continue at the same rate as that observed in the 15 time periods shown, what is the probability that six or more vehicles will arrive in each of the next three 60-second time intervals (12:15 P.M. to 12:16 P.M., 12:16 P.M. to 12:17 P.M., and 12:17 P.M. to 12:18 P.M.)?

Problems 1. Traffic volumes on a four-lane freeway (two lanes in each direction) were counted manually from an overhead location, resulting in the data shown here. The desire was to obtain continuous 15-minute counts for each lane of the freeway for a two-hour period surrounding the morning peak hour. 11On 400 linc W Data for Problem 1 Eastbound Westbound Time of Count (PM) Lane 1 Lane 2 Lane 1 Lane 2 4:00-4:12 4:15-4:27 4:30-4:42 4:45-4:57 5:00-5:12 360 310 350 285 380 330 370 300 370 340 5:15-5:27 5:30-5:42 5:45-5:57 345 280 340 260 310 320 From the data shown, determine the following: (a) Continuous 15-minute volumes for each period and each lane. (b) The peak hour, peak hour volume, and peak hour factor (PHF) for each direction of flow and for the freeway as a whole. (c) Directional flow rates during each 15-minute count period.
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]
