- There is a single gate at an entrance to a recreational park where arriving vehicles must stop to pay their tickets. The park opens at 8:00AM, at which time vehicles begin to arrive at a rate of 480 veh/hr. After 20 minutes the arrival flow rate declines to 120 veh/hr, and it continues at that level for the remainder of the day. If the service time is 15 seconds per vehicle, and assuming D/D/1 queuing, determine the Longest Vehicle Queue. Note: Round off your answers to the nearest whole number. Only include the numeric value of your answer without the unit (i.e. 22).arrow_forwardThere is a single gate at an entrance to a recreational park where arriving vehicles must stop to pay their tickets.

- Vehicles arrive at a single toll booth beginning at8:00 A.M. They arrive and depart according to a uniformdeterministic distribution. However, the toll booth doesnot open until 8:10 A.M. The average arrival rate is 8veh/min and the average departure rate is 10 veh/min.Assuming D/D/1 queuing, when does the initial queueclear and what are the total delay, the average delay pervehicle, longest queue length (in vehicles), and the waittime of the 100th vehicle to arrive (assuming first-infirst-out)?arrow_forwardVehicles arrive at a single toll booth beginning at 7:00 A.M. at a rate of 8 veh/min. Service also starts at 7:00 A.M. at a rate of u(t)=6+0.2t where (f) is in vehicles per minute and it is in minutes after 7:00 A.M. Assuming D/D/1 queuing, determine when the queue will clear, the total delay, and the maximum queue length in vehicles.arrow_forwardThe gate entrance to a park opens at 8:00 AM and there are 18 vehicles in the queue waiting to enter. Vehicles continue to arrive (from 8:00 AM onward) at a constant rate of 8 veh/min. The gate attendant processes vehicles at a constant rate of 1 vehicle every 6 seconds. Assume D/D/1 queuing for the vehicle arrival and departure processes at this gate. What is the average delay per vehicle (min/veh) from 8:00 AM until the queue clears? 0.9 1.1 4.5 9 Ο Ο 81arrow_forward
- Passenger car arrive at the stop sign at an average rate of 280 per hour. Average waiting time at the stop sign is 12 sec. If both arrivals and departure are exponentially distributed, what would be the average delay per vehicle in minutes. Assume both arrival and departure rates are exponentially distributed.arrow_forward4- Vehicles begin to arrive at a toll booth at 7:50 A.M. with an arrival rate A(t) = 5.2-0.01t (with t in minutes and A(t) in vehicles per minute). The toll booth opens at 8 :00 A.M. and serves vehicles at a rate of, u(tt)%=3.3+2.4t (with t in minutes after 8:00 A.M and u(t) in vehicles per minute). Once the service rate reaches 10 veh/min, it stays at that level for the rest of the day. If queuing is D/D/1, when will the queue that formed at 7:50 A.M. be cleared?arrow_forward6. Vehicles begin to arrive at a toll booth at 8:50AM with an arrival rate of (t)=4.1+0.01t with t in minutes and 2(t) in vehicles per minute. The toll booth opens at 9:00AM and process vehicle at a rate of 12 veh/min throughout the day. When will the queue dissipate?arrow_forward

The average arrival rate is 8 veh/min and the average departure rate is 10 veh/min. Assuming D/D/1 queuing, when does the initial queue clear and what are the total delay, the average delay per vehicle, longest queue length (in vehicles), and the wait time of the 100th vehicle to arrive (arrow_forwardA toll booth on a temple is open from 8:00 AM to 12 midnight. Vehicles start arriving at 7:45 AM at a uniform deterministic rate of six per minute until 8:15 AM and from then on at two per minute. If vehicles are processed at a uniform deterministic rate of six per minute, determine the (a) time of queue dissipation in minutes (b) total number of vehicles in queue and (c) total vehicle delayarrow_forwardThe arrival rate at a parking lot is 6 veh/ min. Vehicles start arriving at 6:00 P. M., and when the queue reaches 36 vehicles, service begins. If company policy is that total vehicle delay should be equal to 540 veh-min, what is the service rate? (Assume D/ D/ 1 queuing and a constant service rate.)arrow_forward
