摘要
在城市交通控制中,平面交叉口各方向的交通流在不同时刻是不同的。针对这一特点,介绍了一种采用实时模糊和定时控制对单交叉口多相位信号进行动态控制的系统,并提出了一种改进的单交叉口多相位信号实时配时模型。此模型是在模糊控制的基础上采用遗传算法,不断改进控制规则,优化多相位交叉口信号实时控制模型,对绿灯延长时间进行细微调整,实现实时控制。
In urban traffic control, the traffic volume of different lanes at plane intersection varies with different time. According to the characteristics, one kind of system was described that used real-time fuzzy and the timed control to carry out the dynamic control of the multiphase signal of isolated intersection. First, one kind of improvement multiphase signal real-time timing model of isolated intersection was proposed. This model used the heredity algorithm in the fuzzy control foundation to unceasingly improve the control rule, optimize multiphase intersection signal real-time control model, carrie out the slight adjustment to the green light extension of time and realize real-time control.
