基于“以线带面”的交通信号网络协调控制方法

Coordinated control method of traffic signal network based on "replace surface with line"

为解决城市区域内交通路网拥堵问题,采用"以线带面"的绿波原理,将干线绿波协调控制方法拓展到城市区域绿波中,以实现对城市路网内交通流的协调控制。以减小整体路网平均延误为目标,达到缓解交通压力的目的。以三纵三横理想交通路网为例,利用vissim进行仿真验证,并在路网、流量等配置相同情况下与传统固定信号配时方案进行对比。试验结果表明,基于"以线带面"策略的交通网络协调控制的方法比传统固定信号配时方法更具有优越性。

In order to solve the problem of traffic congestion in the urban area,this paper adopts the green wave principle of"replace surface with line",and extends the green wave coordinated control method of the main line to the urban area green wave to achieve the coordination of the traffic flow in the urban road network.control.To reduce the average delay of the overall road network as the goal,to achieve the purpose of alleviating traffic pressure.Take the ideal traffic network of three verticals and three horizontals as an example,use vissim for simulation verification,and compare it with the traditional fixed signal timing scheme under the same configuration of road network and traffic.The experimental results show that the method of coordinated control of the transportation network based on the"replace surface with line"strategy is superior to the traditional fixed signal timing method.
