The invention provides a key intersection and adjacent intersection traffic signal control method, the key intersection adopts a one-way full-pass control method, and the adjacent intersection of thekey intersection adopts a three-turning traffic flow synchronization control method; and the release time of the adjacent intersection is determined by calculating the phase difference between the keyintersections and the adjacent intersections. The release duration is calculated by using a traffic wave correlation theory, so that a motorcade entering the entrance lane of the key intersection ateach adjacent intersection passes through the key intersection without stopping. The signal control method established by the invention is simple and easy to implement, and a simulation result shows that the signal control method can effectively prevent and improve the congestion condition of the key intersection, avoids the propagation and diffusion of congestion, and makes contribution to the smooth operation of the whole road network.
本发明提供一种关键交叉口及相邻交叉口交通信号控制方法,所述的关键交叉口采用单向全通行的控制方法,关键交叉口的相邻交叉口采用三转向车流同步的控制方法;通过计算关键交叉口和相邻交叉口之间的相位差、确定相邻交叉口的放行时间。利用交通波相关理论计算放行时长,使各相邻交叉口进入关键交叉口进口道的车队不停车通过关键交叉口。本发明建立的信号控制方法简单、易实现,仿真结果表明其可以有效预防、改善关键交叉口的拥堵情况,避免了拥堵的传播和扩散,为整个路网的畅通运行做出了有益贡献。
