QUESTION 26 At an entrance to a toll bridge, four toll booths are open. Vehicles arrive at the bridge at an average rate of 900 veh/h, and at the booths, drivers take an average of 12 seconds to pay their tolls. Both the arrival and departure headways can be assumed to be exponentially distributed How would the average queue length change if a fifth toll booth were opened? a. The average queue length is reduced by 1.17 vehicles D.The average...

Suppose vehicles arrive at a single toll booth according to a Poisson process with a mean arrival rate of 8.4 veh/min. Their service times are exponentially distributed. The mean processing rate is 10 veh/min. a. What is the value of the utilization ratio? b. What is the average length of the queue? c. What is the average waiting time in the queue? d. What is the average time spent in the system?

problem!
5.43 Vehicles arrive at a toll both starting at 7:00 A.M. at a rate of 1(t) = 5.1 – 0.05t [with (t) in veh/min and t in minutes after 7:00 A.M.]. The first operator processes cars at a rate of 3 veh/minute 7:00 A.M. until 7:15 A.M when the person leaves because of illness. From 7:15 A.M to 7:25 A.M, no one is at the toll booth but a...

Problem 4 (25 points) Vehicles begin to arrive at a parking lot at 7:45 A.M. at a constant rate of 4 veh/min and continue to arrive at that rate throughout the day. The parking lot opens at 8:00 A.M. and vehicles are processed at a constant rate of 1 vehicle every 10 seconds. Assuming D/D/1 queuing, answer the following questions: a) Draw the D/D/1 queueing diagram (cumulative number of vehicles vs. time). (5 pts) b) What is size of the...

In a national park in Utah, vehicles begin to arrive at a parking lot at 7:30 A.M. with an arrival rate function (in vehicles per minute) of (t) = 4 -0.02t, where t is in minutes. At 7:40 A.M. the parking lot opens and processes vehicles at a rate of 10 per minute. a) What is the average delay per vehicle? b) What is the maximum queue? c) What is the waiting time of 20th vehicle arrives at...
