Brt Operating Vehicle Departure Interval And Intersection Signal Timing Coordination Study

With the BRT, based on analyzing the service frequency of BRT and the signal control of intersection, this paper puts forward the study about the harmony between the service frequency of BRT and the signal of intersection. At first, this paper analyzes BRT service frequency and intersection signal, and puts forward the interdependency in those. At the same time, this paper uses the microscopic simulation software(VISSIM), sets up the model of traffic simulation satisfied with the conditions, and using the model, outputs the dates of tests that changed the service frequency and signal of intersection, and analyzs these dates. This paper sets up the evaluation system for evaluating the different simulation test schemes, the best test is that the BRT bus travel time and delay time is more short, the number of stopping is small, and other vehicles delay time is more short, queue length is more short and number of stopping is small. Then paper gets the best combination between the service frequency and intersection signal. And this paper runs the regression analysis to these combinations, gets the mathematical model. At the final, this paper verifkates these models in the traffic simulation model, and compares and analyzes these results with the traffic model resultes.
