通过对干道交叉口交通信号协调控制几种常用方法的比较,对干道交叉口交通信号协调控制的3个主要参数,即周期时长、绿信比以及相位差进行详细分析,以传统的韦伯斯特法和数解法为基础,引入先进的FPGA设计理念,提出一种新的基于FPGA的干道交叉口交通信号协调控制优化设计方法,将该方法引入到胜太路沿干道方向的4个交叉路口的交通信号协调控制系统的设计中,进行仿真验证并获得通过。
Through the comparison of several commonly used methods of coordination control of traffic signals at arterial intersections, three major parameters of traffic signal coordination control at arterial intersections, namely, period duration, green ratio and phase difference, are analyzed in detail. With the traditional Webster France and the number of the solution as the basis, the introduction of advanced FPGA design concepts, proposed a new FPGA-based traffic intersections road coordination control optimization design method, the method is introduced to Sheng Tai Road along the direction of the main road at the intersection of four Traffic signal coordination control system design, simulation and passed.
