摘　　要：为了提高干线交通的通行能力,根据相邻路口具有相关性的特点,选取干线上相关的3个交叉口作为研究对象,在周期和相位差确定的基础上,提出一种以平均排队长度为优化目标的模糊协调控制算法.同时,根据具体的路口模型设计了一种使干线上3个相邻路口的交通流协调一致的方法,实现了干线上多交叉路口交通流的相关性.根据焦作市某干线上的具体交通流情况进行仿真验证,结果表明,模糊协调控制算法的配时方案比感应控制算法更加合理,能更好地协调城市干线的红绿灯信号,使平均排队长度减少了4.74辆.In order to improve the trunk road traffic capacity, according to the characteristic of the correlation of adjacent intersections,three correlative intersections in a mainline are selected as the research object. When the cycle length and phase difference are determined,a fuzzy coordinated control algorithm using the average queue length as optimization target is proposed. Meanwhile, a method coordinating the traffic flow of three main adja- cent intersections is designed based on the concrete intersection model, which can realize the correlation of multi-intersection traffic flow. Finally,The simulation for the specific traffic flow situation on one trunk of Jiao- zuo city is carried out, and the result shows that the timing plan of the algorithm can coordinate urban arterial traffic signal better and can make the average queue length for waiting decreased 4.74 vehicles, comparing with existing induction control algorithm.
