摘要
介绍了国内外当前交通信号协调控制方案过渡方法的研究现状,分析比较了现有的干线协调过渡方法。针对当前过渡调整方法对于交通信号控制机如何实现协调方案的快速调整涉及较少,未考虑交通信号机实现过渡调整过程中的实际需求等不足,以当日零点为协调控制方案的起始点,针对交叉口过渡信号周期以及周期调整步幅的取值范围,提出了1种基于周期的交通信号协调控制过渡调整策略,并进行了算例分析。结果表明：该策略能够在1~2个周期内快速调整完毕,减少了信号配时的突变所引发路面交通的剧烈波动,实现了交通流运行的平稳和连续。文中所介绍的算法可以实现不同控制方式之间的切换,也可以用于城市区域协调控制中,具有较广的适用范围和实用价值。
This paper firstly introduces the current research on the transition method of coordinated control scheme,then reviews various arterial coordinated transition method.The current transitional adjustment methods involve rarely in the fast adjustment coordination scheme in traffic signal controller,without considering the requirements of traffic signal controller for transition in the process of adjustment of the actual demand.In this paper,take zero clock as a starting point of coordinated control scheme,aimed at the value range of the transition signal cycle and cycle adjusting step,this paper proposed a coordinated control strategy of traffic signal transition adjustment based on cycle.The results show that this method can quickly adjust in the 1~2 cycles,reduce the fluctuation of road traffic caused by mutation signal timing,and ensure the smooth and continuous operation of traffic flow.This algorithm can realize the switch between different control modes,also can be used for coordination control in urban area,and has a wide scope of application and practical value.
