Vehicles arrive at a toll booth starting at 6 AM at the rate of λ(t) = 5 - 0.05t with λ(t) in veh/min and t in minutes after 6 AM. The first operator processes cars at a rate of 3.5 veh/min from 6 AM until 6:15 AM when the person leaves because of illness. From 6:15 AM to 6:30 AM, no one is at the toll booth but a new operator arrives at 6:30 AM and processes at the rate of µ(t) = 7 + 0.2t (with µ(t) in veh/min and t in min after 6:30 AM). Assuming D/D/1 queuing, determine the following queue characteristics,

1. Time of queue dissipation

2. Average delay

Trucks begin to arrive at a weigh station (with a single scale) at 6:00 AM at a rate of λ(t) = 4.0 – 0.25t (t in minutes and λ(t) in vehicles per minute). The time to weigh each truck is constant 30 seconds. Draw the queuing diagram and determine the following. a) The time when the queue that formed will be cleared b) Maximum queue c) The average delay per truck

A vehicle queue is formed at an entrance to the toll plaza due to a malfunction of one of the toll booths. The malfunction is corrected after 30 minutes, at which time all the toll booths are fully operational. The following is known about the traffic and service rate at the toll plaza: Demand (vehicle arrival rate), constant during the entire time = 29 veh/min Normal toll processing rate (vehicle departure rate) = 34 veh/min Toll processing rate (vehicle departure...

An approach to a signalized intersection has a saturation flow rate of 1800 veh/h. At the beginning of an effective red, there are 6 vehicles in queue and vehicles arrive at 900 veh/h. The signal has a 60-second cycle with 25 seconds of effective red. What is the total vehicle delay after one cycle? What is the maximum length of queuing within this cycle? (assumeD/D/1 queuing)

A four-lane freeway (two lanes in each direction) has the arrival flow rate of λ(t)=40-0.15t (with t in minutes and λ(t) in vehicles per minute). At 7 am, an accident occurred in the northbound and blocked both lanes. Twenty minutes later, one lane was opened. At 7:40 am the accident was cleared and both lanes were opened. The capacity of the highway is 2,200 vehicles per hour per lane if not impacted by an accident. (Assuming D/D/1 queuing). When did...
