摘要: 过饱和交通状态的判别是对过饱和交通信号控制的首要条件,提出了一种结合信号控制优化的交通状态及其真实性的判别方法,避免了由于交通信号控制不合理,尤其是协调控制不合理导致的“假饱和”。利用车头时距的方差和时间占有率作为判别参数结合周期内排队车辆的消散对交通状态进行判别。通过算例和仿真分析结果表明:该方法可以准确、有效地判断过饱和交通状态。

Abstract: Abstract: Oversaturated traffic state identification is the first condition of the oversaturated traffic signal control. The identification method of traffic state and its authenticity combined with signal control optimization was proposed, which avoided the “false saturation” due to the unreasonable traffic signal control, especially the unreasonable coordination control. The headway variance and time occupancy were used as identification parameters, combining with the departure of queue vehicles in a cycle to identify the traffic state. Through analyzing a numerical example and simulation, it is indicated that the proposed method can accurately and effectively judge the oversaturated traffic state.

Key words: traffic and transportation engineering, traffic state identification, oversaturated, signal control optimization, headway variance, time occupancy
