- 9- Vehicles arrive at a recreational park booth at a uniform deterministic rate of 4veh/min. If uniform deterministic processing of vehicles (collecting of fees) begins 30 minutes after the first arrival and the total delay is 3600 veh-min, how long after the arrival of the first vehicle will it take for the queue to be cleared?arrow_forwarddelay? 4. The gate entrance to a park opens at 9:00 A.M. At 9:00 A.M. there are 32 vehicles in the queue waiting to enter. Vehicles continue to arrive (from 9:00 A.M. onward) at a rate of X(t) = 4.2-0.05t (with X(t) in veh/min and t in minutes after 9:00 A.M.). The gate attendant processes vehicles at a rate of u(t) = 3 + 0.3t [with u(t) in veh/min and t in minutes after 9:00 A.M.]. Assuming D/D/1 queuing, what is the maximum queue length and total vehicle delay from 9:00 A.M. onward?

If it takes 1.5 min for the issuance of parking tickets to be bought for occupants of each car. a.) Determine the expected length of queue , not including the vehicle being served. b.) What will be the average waiting time of a vehicle in the queue in min.?arrow_forward
- 7. Queue Theory: At the end of a sporting event, vehicles begin leaving a parking lot at 2(1) = 12 - 0.25t and vehicles are processed at u(t) = 2.5 + 0.5t (t is in minutes and 2(t) and u(t) are in vehicles per minute). Assume D/D/1 determine: Time when queue clears and total vehicle delay.arrow_forwardC. There is a traffic accident happened on EDSA at 6:00 AM the flow rate on that time was 50 veh per min while the normal capacity of EDSA is 60 veh per min but since there is an accident, it reduced to 22 veh per min, the traffic was cleared after 25 minutes. Determine the length of the queue before the removal of blockage. Also calculate the time that vehicles waited a long line before the removal of blockage and when was the queue cleared?arrow_forwardPassenger 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_forward
- The arrival times of vehicles at the ticket gate of a sports stadium may be assumed to be Poisson with a mean of 30 veh/h. It takes an average of 1.5 min for the necessary tickets to be bought for occupants of each car. 6-23 (a) What is the expected length of queue at the ticket gate, not including the vehicle being served? (b) What is the probability that there are no more than 5 cars at the gate, including the vehicle being served? (c) What will be the average waiting time of a vehicle?arrow_forwardVehicles 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_forwardAt an entrance to a toll bridge, four toll booths are open. Vehicles arrive at the bridge at an average rate of 1200 veh/h, and at the booth, drivers take an average of 10 seconds to pay their tolls. Both the arrival and departure rates can be assumed to be exponentially distributed. How would the average queue length, time in the system change if a fifth toll booth were opened?

Beginning at 8 A.M., vehicles are being serviced at a rate of (t) = 2.1 + 0.3t ((t) and (t) are in vehicles per minute and t is in minutes after 8:00 A.M.).

If company policy is that total vehicle delay should be equal to 500 veh min, what is the departure rate?
