Problem 1: Textbook Problem 7.1 W An intersection approach has one left-turn lane. The signal cycle length is C = 90 seconds, which is divided into r= 74 seconds of effective red, followed by g = 16 seconds of effective green. At t = 0 (start of the effective red), there is a queue of 3 vehicles. Left turn vehicles arrive at a constant rate of λ = 200 . During the 16 second effective green time, left-turn vehicles cross the stop line at one vehicle every 2 seconds. veh a. Sketch the graph of cumulative arrivals and departures from t = 0-90 seconds. Shade the area that represents the total delay. b. At t = 90 seconds, how many vehicles arrived? How many vehicles departed?
Subject : Transportation engineering Please give me right solution according to the question...
A two-phase signalized intersection is designed with a cycle time of 100 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)
7.12 The saturation flow rate of an approach to a pretimed signal is 6000 veh/h. The signal has a 60-second cycle with 20 seconds of effective red allocated to the approach. At the beginning of an effective red (with no vehicles remaining in the queue from a previous cycle), vehicles start arriving at a rate v(t) = 0.4 +0.01t + 0.00057+² (where v(t)) is in vehicles per second and t is the number of seconds from the beginning of the cycle). 30 seconds into the cycle the arrival rate remains constant at its 30-second level and stays at that rate until the end of the cycle. What is the total vehicle delay over the cycle (in vehicle- seconds), assuming D/D/1 queuing?
