A signalized intersection has a cycle length of 70 seconds. For one traffic movement, the displayed all-red time is set to two seconds while the displayed yellow time is five seconds. The effective red time is 37 seconds and the total lost time per cycle for the movement is four seconds. What is the displayed green time for the traffic movement in seconds (whole number).
Data from a 6ft by 6ft inductive loop detector collected during a 60 second interval indicates that the mean speed of traffic is 50mph among the 32 vehicles counted. Assume an average vehicle length of 19ft. Calculate a. The density, b. The occupancy, and C. The flow rate during this interval.
8. A four-lane highway has a normal capacity of 1800 veh/hr/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 veh/hr/ lane at this time. At 4:45 p.m., the disabled vehicle is removed from the shoulder and the capacity increases to 1500 veh/hr/lane. At 5:00 p.m. the roadway capacity returns to its full value of 1800 veh/hr/lane. From 4:30 p.m. until the queue clears the traffic flow is 1600 veh/hr/lane. Determine the following: 1. Average delay per vehicle 2. Maximum queue length 3. Average queue length in the southbound direction
A. There is a traffic accident happened on highway at 6:00 AM the flow rate on that time was 50 veh per min while the normal capacity of highway is 60 veh per min but since there is an accident, it reduced to 22 veh per min, the traffic was cleared after 25 minutes. Determine the length of the queue before the removal of blockage. Also calculate the time that vehicles waited a long line before the removal of blockage and when was the queue cleared?

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)?
F] Vehicles travel at constant speeds on a one-lane one-way street between sections X and Y. An observer located at point X observes the four vehicles passing point X during a period of 10 seconds. The speeds of the vehicles are measured as 45, 45, 40, and 30mph, respectively. Calculate the average flow, density, time mean speed, and space mean speed.
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.
