The invention discloses an urban road traffic flow traceability method and system, and belongs to the technical field of intelligent traffic, and the method comprises the steps: collecting vehicle data; data preprocessing: carrying out preprocessing operation on the collected vehicle data; data storage: storing the preprocessed vehicle data in a cloud server; vehicle driving information analysis: analyzing each node passed by the vehicle through machine learning; generating a vehicle track, connecting each node passed by the vehicle into a line by using a road according to a time sequence, and forming track information of the vehicle in a city form; and traffic flow trajectory generation: superposing the linear trajectories of the vehicles on a map to form traffic flow trajectory information, and visualizing sources and destinations of the vehicles on one or more roads. According to the method, more refined traffic flow trajectory data support can be provided for a traffic control department, the refinement of a traffic signal timing scheme and the scientization of communication guidance are improved, and the practical value and the economic value are high.

    本发明公开了一种城市道路车流溯源方法及系统,属于智慧交通技术领域,该方法的实现包括:车辆数据采集;数据预处理,对采集到的车辆数据进行预处理操作;数据存储,将预处理后的车辆数据存储到云端服务器中;车辆行驶信息分析,通过机器学习对车辆经过的每个节点进行分析;车辆轨迹生成,根据时间顺序利用道路将车辆经过的每个节点连接成线,形成车辆在城市形式的轨迹信息;交通流轨迹生成,在地图上将车辆的线性轨迹进行叠加,形成交通流的轨迹信息,可视化一条或多条道路车辆的来源和去向。本发明可以为交管部门提供更加精细化的车流轨迹数据支持,提高交通信号配时方案的精细化与交流引导的科学化,具有较高的实用价值和经济价值。
