本文提出了一种城市道路交叉口的实时交通信号控制模型,解决了交通拥挤问题。利用释放矩阵对交通流量的现状进行了分析,并提出了交叉口车辆总延误时间最小化的基本模型。利用Webster配时法优化模型并建立了实时非平稳周期交通信号模型。最后将仿真结果与传统模型进行比较,验证了所提出模型的有效性。

In this paper, a real-time traffic signal control model for urban road intersection is proposed, which solves the problem of traffic congestion. The current situation of traffic flow is analyzed by using the release matrix, and the basic model of minimizing the total delay time is proposed. The Webster timing method is used to optimize the model and a real-time non-stationary periodic signal model is established. Finally, the simulation results are compared with the traditional models, and the effectiveness of the proposed model is verified.
