摘要/Abstract

摘要： 随着城市道路交通量的增长、路网密度的增大,相邻路口之间的相关性日益明显。一个路口交通信号的调整往往影响到相邻若干个路口交通流的运行状况,其拥堵可能会随着时间推移逐步波及周边数个路口乃至所在区域内所有路口。因此应利用各种先进的控制技术对相邻路口的控制参数进行调整,实现区域乃至整个城市范围内对交通进行动态协调控制,以满足日益增长的交通需求,使交通道路供给与交通需要间达到动态平衡。文中利用绿波效应协同策略对干道相邻路口绿灯延长时间进行模糊控制,以解决交叉口之间耦合性的问题,该算法能够比较灵活地进行信号配时。通过实验仿真,验证了本方法在干道城市交通系统中的可行性。

Abstract: With growth of urban road traffic volume and the increase of road network density,correlation between adjacent road intersections is becoming more and more obvious．An intersection traffic signal adjustment tends to affect the health of a number of adjacent intersections road traffic flow．Its congestion may over time gradually spread to within a few blocks and regions all around the intersection．Therefore increasingly high demands of urban traffic signal control to reach a variety of advanced control technology integration,achieve the purpose to adjust a control parameter,in order to achieve dynamic coordination within the city-wide traffic control,to satisfy traffic demands,and then let the road traffic and the transport demand to reach a new balance．This article introduced the use of the green wave effect collaborative strategies adjacent green extension of fuzzy control in order to solve the problem of coupling between intersections road．This algorithm makes Signal Timing to be more flexible.

Key words: Intersection,Green-wave effect,Cooperative policies,Signals fuzzy control
