The invention discloses a two-phase traffic signal timing method, and relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining the input parameters of two-phase traffic signal timing; the input parameters comprise a coordination period, traffic flow, a minimum value of a distance to a previous intersection, a maximum value of a two-way traffic flow difference value and a minimum value of the two-way traffic flow difference value; a fuzzy control model is constructed, a green time ratio is determined based on the fuzzy control model, and the fuzzy control model takes the input parameters as input and takes the green time ratio as output; and obtaining two-phase traffic signal timing based on the green signal ratio output by the fuzzy control model. According to the invention, an input parameter is innovatively put forward, and the distance from the previous intersection is taken as a consideration factor, so that signal timing is more synergetic, and a given timing scheme is more effective.

    本发明公开了一种二相位交通信号配时方法,涉及智能交通技术领域,该方法包括:获取二相位交通信号配时的输入参数;所述输入参数包括:协同周期、车流量、距上一个路口距离最小值、双向车流量差值最大值、双向车流量差值最小值;构建模糊控制模型,并基于所述模糊控制模型确定绿信比,所述模糊控制模型以所述输入参数为输入,以绿信比为输出;基于所述模糊控制模型输出的绿信比,得到二相位交通信号配时。本发明创新性的提出输入参数采用距离上一个路口距离作为考虑因素,这样使得信号配时更具用协同性,给出的配时方案更具有效果。
