摘要
针对目前交叉路口交通控制信号灯的绿信比固定不变的问题,提出一种模糊控制的方案。根据当前相位的车流量和当前相位与下一相位车流量之差,实时控制相位绿信比,缩减车辆在交叉路口的排队长度。绿信比可在FPGA上模拟实现,采用E-Elements ISE Development Kit开发套件,使用ISE10.1软件设计工具,对上述控制方案进行仿真。
The current split of intersection traffic control signal lights is fixed, so a fuzzy control scheme is proposed. The split is controlled in real-time according to the traffic flow of current phase and the traffic flow difference between current phase and next phase, so as to reduce waiting vehicles at the intersection. The split is implemented based on FPGA. The scheme is emulated using E-Elements ISE Development Kit and software design tool ISE10.1.
