A travel time study conducted on I-77 in the Charlotte metropolitan area shows that it takes 45 minutes to travel from exit 1 to exit 28 (northbound direction) during evening peak hours. Contrarily, it only takes 29 minutes to travel the same distance during evening off-peak hours. Calculate travel rate, delay rate, relative delay rate, and delay ratio for this 28-mile section. Calculate the total vehicle delay and total person delay if the average traffic volume is 3,600 vehicles and average vehicle occupancy is 1.2 during the peak hour. Also, calculate the vehicle miles traveled (VMT) and person miles traveled (PMT).

On a given day, 425 veh/h arrive at a tollbooth located at the end of an off-ramp of a rural expressway. If the vehicles can be serviced by only a single channel at the service rate of 625 veh/h, determine (a) the percentage of time the operator of the tollbooth will be free, (b) the average number of vehicles in the system, and (c) the average waiting time for the vehicles that wait. (Assume Poisson arrival and negative exponential service time.)
determine the accident rate. If the number of accidents for 7 years recorded in a certain intersection is 5877 and if the average daily traffic is 485.
An expressway consists of four lanes, where the capacity per lane is 2500 vehicles. In normal days, 6500 vehicles pass. However, there is an emergency road repair conducted in which two lanes will be closed. The repair lasted 150 minutes. Calculate the maximum queue length, total length, and number of vehicles impacted by the event, and average individual delay.
In speed and delay study, if the average journey time on a stretch of road length of 3.5 km is 7.55 minutes and the average stopped delay is 1.8 minutes, then the average running speed will be (a) 36.5 kmph (c) 38.5 kmph (b) 37.5 kmph (d) 39.5 kmph
Off-ramp traffic must stop at a single tollbooth. The arrival rate at the tollbooth is 45 vehicles per hour. If the service rate is 60 vehicles per hour, determine the number of vehicles waiting excluding the vehicles being served.
5-10. The following travel times were measured for vehicles traversing a 1,000-ft segment of an arterial: Vehicle Travel Time (s) 20.6 2. 21.7 1 3 19.8 4 20.3 5 22.5 6 18.5 7 19.0 8 21.4 Determine the time mean speed (TMS) and space mean speed (SMS) for these vehicles.
The rate of arrival of vehicles at the expressway can be considered to be Poisson with a mean of 45 veh/hr, and the rate of service to vehicles can be assumed to be exponentially distributed with a mean of 1 min. (a) What is the average number of vehicles waiting to be served at the booth (that is, the number of vehicles in queue, not including the vehicle being served)? (b) What is the length of the ramp required to provide storage for all exiting vehicles 90% of the time? Assume the average length of a vehicle is 18 ft and that there is an average space of 10 ft between consecutive vehicles waiting to be served. (c) What is the average waiting time a driver waits before being served at the tollbooth (that is, the average waiting time in the queue)?
The minimum cycle length for an intersection is determined to be 95 seconds. The critical lane group flow ratios were calculated as 0.235, 0.250, 0.170, and 0.125 for phases 1–4, respectively. What Xc was used in the determination of this cycle length, assuming a lost time of 5 seconds per phase?
When an incident occurs that causes two lanes to be closed, a three-lane highway in one direction is carrying a total volume of 4700 veh/h. Calculate the maximum queue length, total delay, number of vehicle impacted by the event and average individual delays if the highways capacity is 2550 veh/h/ln. It takes 120 minutes to clear the obstacle.
At exactly 8:05AM, vehicles start to enter a single toll gate at rate of 7veh/min following deterministic distribution. Due to teller being late, the toll booth opened at 8:20AM having a service rate of 8.5veh/min. Determine the time of queue dissipation, total vehicles at queue dissipation, longest vehicle delay, longest vehicle queue, total vehicle delay, and average delay per vehicle.
The number of vehicles that can enter the on-ramp of Subic-Clark Expressway is controlled by a metering system. If the vehicles can enter the expressway at a rate of 500 veh/hr, and the rate of arrival of the vehicles at the on-ramp is 400 veh/hr during the peak hour. Determine the expected number of units waiting to be served in the system.
The uniform arrival and uniform service rates observed on an approach road to a signalized intersection are 20 and 50 vehicles/minutes, respectively. For this signal, the red time is 30 s, the effective green time is 30 s, and the cycle length is 60s. Assuming that initially there are no vehicles in the queue, the average delay per vehicle using the approach road during a cycle length (in seconds, round off to 2 decimal places) is
