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 A(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?

11-Vehicles begin to arrive at a parking lot at 6:00A.M. at a rate of eight per minute. Due to an accident on the access highway, no vehicles arrive from 6:20 to 6:30 A.M. From 6:30 A.M. on, vehicles arrive at a rate of two per minute. The parking lot attendant processes incoming vehicles (collects parking fees) at a rate of four per minute throughout the day. Assuming D/DA queuing, determine total vehicle delay.
Consider an entrance of a parking on a certain mall, having an arrival rate of 210 veh/hr and Poisson distributed, and a deterministic departure rate of 215 veh/hr. Compute for the average time spent in the system. ○ 6.35 min 5.40 min ○ 6.14 min ○ 5.82 min
Through the Walla Walla Road to the entrance of the E-1 parking lot at the University of Washington, vehicles begin to arrive from 7:40 A.M. at a uniform deterministic rate of 480 vph until 8:20 A.M. and from then on at 120 vph. It takes 10 seconds for a vehicle to go through the paying process at the gate. If the parking lot is open at 8:00 A.M., determine (a) when the queue will dissipate, (b) the total delay, (c) the average delay, (d) the maximum queue length (in vehicles), and (e) the longest vehicle delay under FIFO. Show your results graphically. [Hint: D/D/1 analysis]
Question 4 Vehicles begin to arrive at a border gate at 06h50 with a deterministic arrival rate of λ (t) = 5.2 - 0.01t (λ is in vehicles per minute and t in minutes after 06h50). However, the gate opens at 07h00 and serves vehicles at a rate of μµ(t) =3.3 + 2.4t (with t in minutes after 07h00 and u in vehicles per minute). Once the service rate reaches 10 vehicles per minute, it stays at that level for the rest of the day. ● ● Illustrate the operational characteristics of the vehicle queue-delay on a (cumulative) vehicle-Time graph. When will the queue that forms be dissipated? What will be the maximum queue length? Determine the total delay.
Vehicles arrive to the park entrance at a constant rate of 900 veh/hour from 7:30 AM to 8:10 AM and then at a constant rate of 600 veh/hour from 8:10 A.M. The park opens at 8:10 A.M. and the manager wants to set the departure rate so that the average delay per vehicle (i.e.: Total delay/total number of arrival) is no greater than 24 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? What is the total delay at this rate? What is the longest Queue?
Cars have a long queue at a stop sign. If the total time delay queueing is one min., compute the traffic intensity if the service rate of the road is only 360 veh/ hr. Assume both arrival and departure rates are exponentially distributed.
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.
A 14-km streetcar line travels eastbound and westbound in shared ROW, and in each direction, it has stops every 250 m. Because the line is heavily used, it has a headway of 2.5 min and streetcars stop at each service stop. The running speed of streetcars between stops is 25 km/h (not accounting for stopping at stops). At each stop, streetcars spend 30 sec in acceleration, deceleration and dwell time. The terminal time is 10 min/terminal. The line is being redesigned into a high-quality streetcar line. The new streetcars have double the capacity of existing cars, and the headway of the new line will be increased to 5 min (although some passenger trips might be lost due to the increased stop spacing and increased headway, the travel demand is expected to be at least the same because of the overall performance improvement of the line). Two options are being considered: Option 1: The new stop spacing is 300m. The new line is expected to have a running speed of 40 km/h and the stop time…
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
Compute the peak hour factor if the hourly volume of traffic is 1800 vehicles/hour and the highest 20-min. volume is 800.
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 8:00 A.M., the average arrival rate be 240 veh/h and Poisson distributed (exponential times between arrivals) over the entire period from park opening time (8:00 A.M.) until closing at dusk. If the time required to distribute the brochure is 10 seconds, the distribution time varies depending on whether park patrons have questions relating to park operating policies, assuming M/M/1 queuing. a.) Compute the average length of queue (express in veh), b.) Average waiting time in the queue (express in min/veh), c.) and average time spent in the system(express in min/veh)
