Micro-simulation Analysis for Capacity of Intersection under Different Control Methods
不同控制方法下交叉口通行能力的微观仿真剖析

A fuzzy control model for signalized intersection is proposed,and it is compared with fixed-cycle and vehicle-actuated control by using simulation technology.The internal relationship between the variation of traffic flow status and the control method is analyzed from multiple micro-viewpoints,such as a lane's queue length,average waiting time,counts of the green light,green time and rate of the passed vehicles.Traffic efficiency and fairness of three control methods are compared from multiple macro-viewpoints,such as the intersection's average delay,uniformity of the green time and number of the passed vehicles.The simulation analysis of micro process supplies a new idea for researching traffic control,and the macro result indicates that the traffic is more efficient and fair under the control of our model.
