- The following data was collected during a study of two arterial lanes. Estimate the continuous 15-minute counts for the two-lane roadway as a whole. Find the peak hour, and compute the PHF.TRANSPORTATION ENGINNERING-TRAFFIC SIGNALS An approach to a predetermined signal has 25 seconds of effective green for a 60 second cycle. The approach volume is 500 vehicles/hour and the saturation flow rate is 1400 vehicles/hour. Calculate the average vehicle delay using D/D/1 queing.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]
- Problems 1. Traffic volumes on a four-lane freeway (two lanes in each direction) were counted manually from an overhead location, resulting in the data shown here. The desire was to obtain continuous 15-minute counts for each lane of the freeway for a two-hour period surrounding the morning peak hour. 11On 400 linc W Data for Problem 1 Eastbound Westbound Time of Count (PM) Lane 1 Lane 2 Lane 1 Lane 2 4:00-4:12 4:15-4:27 4:30-4:42 4:45-4:57 5:00-5:12 360 310 350 285 380 330 370 300 370 340 5:15-5:27 5:30-5:42 5:45-5:57 345 280 340 260 310 320 From the data shown, determine the following: (a) Continuous 15-minute volumes for each period and each lane. (b) The peak hour, peak hour volume, and peak hour factor (PHF) for each direction of flow and for the freeway as a whole. (c) Directional flow rates during each 15-minute count period.i need the answer quickly6-A toll booth on a turnpike is open from 8:00 A.M. to 12 midnight. Vehicles start arriving at 7:45 A.M. at a uniform deterministic rate of six per minute until 8:15 A.M. and from then on at two per minute. If vehicles are processed at a uniform deterministic rate of six per minute, determine when the queue will dissipate, the total delay, the maximum queue length (in vehicles) and the longest vehicle delay.
- Studies have shown that the traffic flow on a two-lane road adjacent to aschool can be described by the Greenshields model. A length of 0.5 miadjacent to a school is described as a school zone and operates for a periodof 30 min just before the start of school and just after the close of school.The posted speed limit for the school zone during its operation is 15 mi/h.Data collected at the site when the school zone is not in operation showthat the jam density and mean free speed for each lane are 125 veh/mi and57 mi/h. If the demand flow on the highway at the times of operation ofthe school zone is 90% of the capacity of the highway, determine: The speeds of the shock waves created by the operation of the schoolzone, and• The number of vehicles affected by the school zone in the upsream ofthe zone during this 30-minute operation.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?None
