The invention discloses an intersection signal timing method based on low-permeability networked vehicle trajectory data. The method comprises the following steps: constructing a low-permeability networked vehicle road network with an intersection signal timing optimization requirement based on an SUMO simulation platform; inputting data into the constructed road network, defaulting a traffic flow model defined by the SUMO simulation platform, designing a low-permeability networked vehicle road network scene, and simulating the road network traffic flow condition; in the simulated road network traffic flow condition, for each signal period, network connection vehicle track data is randomly selected as sample data, and the selected network connection vehicle track data accounts for 3%-5% of the whole road network traffic flow track data; determining a traffic signal plan of a next signal period at the end of a previous signal period according to the selected networked vehicle trajectory data; signal timing of the road network in the SUMO simulation platform is modified according to the traffic signal plan of the next signal period until simulation is finished, and the problems of preventing intersection overflow, relieving road network congestion and the like are achieved.

    本发明公开了基于低渗透率网联车轨迹数据的交叉口信号配时方法,包括:基于SUMO仿真平台构建一个有交叉口信号配时优化需求的低渗透率网联车路网;向构建的路网中输入数据,默认SUMO仿真平台定义的车流模型,设计低渗透率网联车路网场景,模拟路网车流情况;在模拟的路网车流情况中,对于每个信号周期,随机选取网联车轨迹数据作为样本数据,且选取的网联车轨迹数据占整个路网车流轨迹数据的3%‑5%;根据选取的网联车轨迹数据,在上一个信号周期结束时确定下一个信号周期的交通信号计划;根据下一个信号周期的交通信号计划修改SUMO仿真平台中路网的信号配时,直至仿真结束,实现预防交叉口溢出、缓解路网拥堵等问题。
