A four-lane highway has a normal capacity of 1800 vehicles per hour per lane. In the
southbound direction, a vehicle disablement on the roadway shoulder occurs at 4:30 p.m.
Due to rubbernecking, the capacity in the southbound direction is reduced to 1200
xsh/h/lane at this time. At 4:45 p.m., the disabled vehicle is removed from the shoulder
and the capacity increases to 1500 yeh/h/lane. At 5:00 p.m., the roadway capacity returns
to its full value of 1800 ysh/h/lane. From 4:30 p.m. until the queue clears the traffic flow
rate in the southbound direction is 1600 xsh/h/lane. What is the average delay per
vehicle, the maximum queue length, and the average queue length in the southbound
direction resulting from the incident (assuming D/D/1 queuing)?

- Problem 2: A Class III two-lane highway is on level terrain, has a measured free-flow speed of 45 mi/h, and has 100% no-passing zones. During the peak hour, the analysis direction flow rate is 150 veh/h, the opposing direction flow rate is 100 vehh, and the PHF = 0.95. There are 5% large trucks and 10% recreational vehicles. Determine the level of service.arrow_forward1) A 6-lane two-way arterial road has a maximum flow of 6,000 vehicles per hour on one direction. It is operating at 3,600 vehicles per hour at time, t=0. A collision occurs, blocking the two lanes, and restricting the flow of the outermostlane to 1,600 vehicles per hour. After 40minutes, the police have cleared the middlelane from accident debris; the operating volume at that time increased to 2,400 vehicles per hour.20 minutes past, the innermost lane was finally cleared of the accident. Traffic returns to normalas soon as the queue has already immoderate. a.Determine the maximum length of queue that occurred. b.How long did it take to dissipate the queue? c.If a vehicle entered the road at t=10 minutes, how long will it take for it to leave the traffic?arrow_forwardA segment of eight-lane urban freeway experiences a breakdown that blocks two lanes completely for a period of one hour in the peak direction. The breakdown occurs at 9:00 AM and is cleared by 10:00 AM. The capacity of the segment is 2,100 veh/h/In, with a maximum queue discharge rate of 1,800 veh/h/ln.

- A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The traffic stream consists of mostly commuters with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service? (Write the letter only)arrow_forwardProblem 2. Consider a freeway section with three lanes in each direction and with a length of 1.25mi (2km) and a +5% grade. In this freeway, the directional peak-hour volume is 3,800 veh/h, from which 76 are trucks and 152 are transit buses. The maximum 15-min volume within the hour of analysis is 1,055 vehicles. The lane widths are 12 ft (3.6m), and shoulder widths are 10 ft (3.1m). There are 2 exit ramps and 1 entrance ramp in the 3 miles in the upstream section and 1 exit ramp and 2 entrance ramp in the 3 miles in the downstream section (consider the same ramp density if using international (km) units). All transit buses will be removed from traffic since the transit service will be replaced by a commuter rail service. However, by removing buses, new additional passage car demand is expected. It is estimated that for each removed bus, 7 new passenger cars will be added to the original traffic volume of 3,800 veh/h.
