The invention relates to a traffic signal lamp real-time control method and system based on a combined control strategy. The traffic signal lamp control method comprises the steps of determining a target traffic flow direction and a corresponding green light duration according to an actually measured traffic flow by taking a green light duration and a signal state as controllable variables, determining road saturation of each traffic flow direction, determining a traffic flow of each traffic flow direction, determining a red light waiting duration of each traffic flow direction, and changing the direction of the target traffic flow according to the conditions. According to the traffic signal lamp real-time control method and system based on the combined control strategy, the adaptive signal control strategy is selected under different traffic conditions, and the traffic signal lamp real-time control method and system automatically adapt to the flow condition. According to the method, emergency situations can be handled in time, the intersection traffic efficiency is improved, refined and intelligent control over intersection signals is achieved, and the problems that the intersection congestion phenomenon occurs frequently, and a signal lamp control method is poor in accuracy and flexibility are solved.

    本发明涉及一种基于组合控制策略的交通信号灯实时控制方法及系统。所述交通信号灯控制方法包括:根据实测车流量,以绿灯时长和信号状态作为可控变量,确定目标车流方向以及对应的绿灯持续时长、确定各车流方向的路段饱和度、确定各车流方向的车流量、确定各车流方向的红灯等待时长,并根据这些条件改变目标车流方向。本发明提供的一种基于组合控制策略的交通信号灯实时控制方法及系统实现了在不同的交通情况下选择适应的信号控制策略,自动适应流量情况。该方法能够及时处理紧急情况,提升了交叉口通行效率,使得交叉口信号达到精细化和智能化控制,解决了交叉口拥堵现象频发,信号灯控制方法的精确性、灵活性较差等问题。
