1) (50 Points) A section of the highway has a speed-flow relationship of the form q=au? +bu It is known that at capacity (which is 2900 veh/h) the space-mean speed of traffic is 50 km/h. Determine the speed when the flow is 1400 veh/h and the free-flow speed. 2) (50 Points) Commercial trucks begin to arrive at a seaport entry plaza at 7:50 a.m., at the rate of (t) = 6.3 -0.25t veh/min, with t in minutes. The plaza opens at 8:00 a.m. For the first 10 minutes, one processing booth is open. After the first 10 minutes until the queue clears, two processing booths are open. Each booth processes trucks at a uniform rate of 2 per minute. What is the average delay per vehicle, the maximum queue length, and the average queue length?
