A section of Texas Highway 83 (Tx83) has a capacity in the eastbound direction of 4,000 vehicles per hour and a constant flow of 2,900 vehicles per hour during the morning commute. At 7:00am, a traffic accident closes the highway to all traffic (eastbound and westbound). At 7:12am, the highway is partially opened in both directions with a capacity in the eastbound of 2,000 vehicles per hour. Finally, the wreckage is removed, and the highway is restored to full capacity at 7:31am. Determine the total delay (in vehicle minutes) and the longest queue length in vehicles as well as the longest wait of any vehicle (in minutes).

An incident occurs on a freeway that has a capacity in the northbound direction, before the incident, of 4000 veh/h and a constant flow of 2900 veh/h during the morning commute (no adjustments to traffic flow result from the incident). At 8:00 A.M. a traffic accident closes the freeway to all traffic. At 8:12 A.M. the freeway is partially opened with a capacity of 2000 veh/h. Finally, the wreckage is removed, and the freeway is restored to full capacity (4000 veh/h) at 8:31 A.M. Assume D/D/1 queuing to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and longest wait of any vehicle (assuming FIFO)
An incident occurs on a freeway that has a capacity of 3,500 veh/h in the northbound direction. The arrival flow rate was of 2,500 veh/h during the morning commute. At 7:30 AM, a traffic accident occurs which closes the freeway to all traffic. At 7:42 AM, freeway is partially opened with a capacity of 1,750 veh/h. Finally, the wreckage is removed, and the freeway is restored to full capacity (3500 veh/h) at 8:01 AM. Assume D/D/1 queuing to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and the longest wait of any vehicle (assuming FIFO).
An eight-lane freeway has a capacity of 8000 vehicles hour in each direction under normal conditions. On a particular day, an accident occurs at 8:00 am. Initially, two lanes are blocked, which reduces the capacity of the freeway past this point to 2,000 vehicles per hour. At 8:45, the accident is removed from the traffic lanes, which increases capacity past this point to 4000 vehicles per hour, and at 9:00 it is removed completely, which restores capacity to 8000 vehicles per hour. Demand past the point of the accident is shown below. Finish the following table and draw the queuing diagram.

A freeway with two northbound lanes is shut down because of an accident. At the time of theaccident, the traffic flow rate is 1200 vehicles per hour per lane and the flow remains at this level.The capacity of the freeway is 2200 vehicles per hour per lane when not impacted by an accident.The freeway is shut down completely for 20 minutes after the accident and then one lane is openfor 20 minutes and finally both lanes are opened (40 minutes after the accident). What is theaverage delay per vehicle resulting from the accident (assuming D/D/1 queuing)?
Traffic flow on a four-lane (one direction) freeway can be described by the Greenshields model. Two lanes of the four lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hr. The mean free speed of the highway is 60 mi/h and the jam density is 140 veh/mi/ln. If it is estimated that the demand flow on the highway during the emergency repairs is 80% of the capacity, using the deterministic approach, determine: (a) The maximum queue length that will be formed (b) The total delay(c) The number of vehicles that will be affected by the incident(d) The average individual delay
Scheduled maintenance will close two of the four westbound lanes of a freeway during one weekday for the period from 9:00 AM to 4:00 PM. The demand on the two lanes are as follows: Time Demand, vph 9:00-10:00 AM 4000 10:00-11:00 AM 3500 11:00-12:00 NN 2500 12:00-1:00 PM 2000 1:00-2:00 PM 2000 2:00-3:00 PM 2000 3:00-4:00 PM 2000 If the estimated capacity of the 4 lanes with 2 lanes open is 2960 vph, a. compute the time when maximum queue occurs. 11:00 AM b. compute the maximum queue formed. 1580 vehicles c. compute the maximum length of queue if the average length of cars is equal to 5 meters. 1975 m Show all necessary diagrams and solutions.
A new 4-mile long elevated roadway is constructed to give a direct traffic route from a major residential area over a swamp area to the industrial complex of a city. At present, those traveling from the residential area must take a 15-mile circuitous route either to the north or to the south of the swamp area. The travel time and cost is about the same for both. There are currently 3,000 vehicles on the north route and 4,000 on the south route on a daily basis. The new roadway is designed for a 30-year service-life and be tolled, which involves $40 million for construction and an additional $150,000 per year for toll collection. The toll rate is set at 60 cents per vehicle. Upon opening to traffic, the new roadway is expected to carry 20,000 vehicles per day. Those using the new roadway will drive an average of 2 miles to get to the entrance. Road maintenance costs in the county average $20,000 per mile per year. If vehicle operating costs average 14 cents per mile and the highway…
Traffic flow on a three-lane (one direction) freeway can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 35 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 50 mi/h and the jam density is 115 veh/mi/In. If it is estimated that the demand flow on the highway during the emergency repairs is 85 percent of the capacity, using the deterministic approach, determine the following. (a) the maximum queue length (in veh) that will be formed Your response differs from the correct answer by more than 10%. Double check your calculations. veh (b) the total delay (in h) h (c) the number of vehicles that will be affected by the incident veh (d) the average individual delay (in min) min

A four-lane undivided multilane highway (two lanes in each direction) has 11-ft lanes, 4-ft shoulders, and 10 access points per mile. It is determined that the roadway currently operates at capacity with PHF= 0.80 and a driver population adjustment of 0.9. If the highway is on level terrain with 8% large trucks and buses (no recreational vehicles) and the speed limit is 55 mi/h, what is the directional hourly volume?
An incident occurs on a freeway that has a capacity in the north bound direction, before incident, of 4000 veh/h and a constant flow of 2900 veh/h during the morning commute (no adjustments to traffic flow result from the incident). At 8:00am, a vehicle crash closes the freeway to all traffic. At 8:12am, the freeway is partially opened with a capacity of 2000 veh/h. Finally, the crash site is removed and the freeway is restored to full capacity of 4000 veh/h at 8:31am. Assuming the traffic follows a D/D/1 queueing (FIFO queue discipline) to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and longest wait of any vehicle.
