7) In studying of traffic flow at a highway toll booth over a course of 60 minutes, it is determined that the arrival and departure rates are deterministic, but not uniform. The arrival rate is found to vary according to the function A(t) = 1.8+0.25t - 0.00312. The departure rate function is u(t) = 1.4 +0 .1lt. In both of these functions, t is in minutes after the beginning of the observation and (t) and „u(t) are in vehicles per minute. At what time does the maximum queue length occur? a) 49.4 min, b) 2.7 min ,c) 19.4 min, d) 60.0 min

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Three seconds after automobile B passes through the intersection shown, automobile A passes through the same intersection. Given, the speed of automobile A is VA = 55.00 mi/h and automobile B is vg= 34.00 mi/h, respectively. Also, know that the speeds are constant for the automobiles during the encounter. N 70° S + VA vB Determine the distance between the two automobiles 2 s after A has passed through the intersection. The distance between the two automobiles 2 s after A has passed through the intersection is

(b) Consider a stop-controlled intersection between a major and a minor street shown in the figure below. Traffic on the major street is arriving in a random manner (Poisson distributed vehicle arrivals) and passes through the intersection unimpeded, without having to stop. Traffic on the minor street must wait at the stop sign and can enter the major street only when there is a minimum headway tm = 2.5 seconds (gap) in the major street. Suppose that the flow rate on the major street is Q= 200 vehicles per hour, and only one vehicle can enter the major street during each acceptable gap. Estimate the maximum number of vehicles per hour that can be accepted to the major street (which is also the capacity) of the minor street approach. Major Street Minor Street
