C. 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?

A. There is a traffic accident happened on highway at 6:00 AM the flow rate on that time was 50 veh per min while the normal capacity of highway 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?
vehicles start to arrive at a parking area at 6 am with an arrival rate function(vehicles per minute) of lambda(t)=1.2+(0.3)t, where t is in minutes. At 6:15 am, the parking area opens and processed vehicles at a rate of 12 per minute. a)Determine when does the queue clear? b)find the total delay? c)find the maximum queue length?
2. Congestion starts at 6am in an expressway. Survey found out that an average of 600vph entered the expressway for the 1* 30minutes, reduced to 250vph and remain constant for the succeeding hours. The booth teller took approximately 10sec to render its service for every vehicle. a. Determine the time of dissipation b. Calculate the total number of vehicles entered for this duration Determine the queue and delay after 45mins from the start of rush hour d. Calculate the delay experienced by the 100th vehicle C.
3-The 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 500 veh min, what is the departure rate? (Assume D/D/1 queuing and a constant service rate.)
The 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. The company policy states that the total vehicle delay should be equal to 500 veh-min. Assuming D/D/1 queuing and a constant service rate, determine the maximum queue length.
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?

2. A public administration holds its flag ceremonies every Monday from 07:00 am –07:15 am. During the singing of National Anthem –which lasts for 2 minutes –all drivers stop in front of the building as a sign of respect. a.Determine the maximum length of queue formed. b.Estimate the time required for the traffic flow to be back to normal.
Vehicles begin to arrive at a park entrance at 7:45 A.M. at a constant rate of six per minute and at a constant rate of four vehicles per minute from 8:00 A.M. on. The park opens at 8:00 A.M. and the manager wants to set the departure rate so that the average delay per vehicle is no greater than 9 minutes (measured from the time of the first arrival until the total queue clears). Assuming D/D/1 queuing, what is the minimum departure rate needed to achieve this
SEAT WORK: EA4 Queving theory: D/D/1 Vehicles arrive at an entrance to a recreational park. There is a single gate (at which all vehicles must stop), where a park attendant distributes a free brochure. The park opens at 9:00 A.M., at which time vehicles begin to arrive at a rate of 470 veh/h. After 20 minutes, the arrival flow rate declines to 115 veh/h, and it continues at that level for the remainder of the day. If the time required to distribute the brochure is 14 seconds, and assuming D/D/1 queuing, describe the operational characteristics of the queue.
The 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. The company policy states that the total vehicle delay should be equal to 500 veh-min. Assuming D/D/1 queuing and a constant service rate, at what time did the queue clear?
