摘要
针对城市道路交通拥堵问题,本文提出了一种基于诱导条件下的交通信号控制方法,该方法根据城市道路交通状况调节信号机的绿信比,采用在诱导路径的诱导方向进行线协调控制,并借助微观仿真软件VISSIM进行仿真验证,仿真结果表明,在延长交通拥堵路段的绿灯配时的同时,增加了诱导路段的绿灯时间,且有效缓解了交通拥堵状况。该研究为交通诱导系统中的信号调节方案提供了理论支持,具有广泛的实用性。
Intelligent traffic guidance system can effectively solve the urban road traffic congestion problems, and the signal control is the core of the system. In this paper, an induced condition based traffic signal control method is given according to the urban road traffic control signal of the split ratio. This method is used in induction path induced direction line coordination control. Experiment results show that, in the induction system to calculate the best induced path conditions, using split ratio method can effectively alleviate traffic congestion status. The traffic signal control scheme of the guidance system can provide theoretical support,and has the broad practicability.
