The invention provides a WebGIS-based urban freight visualization method and system. The method comprises the steps of collecting urban freight vehicle data in a vehicle-mounted satellite positioning system; training a congestion index prediction model, and predicting congestion indexes of different traffic roads in the freight visualization model; marking a grading result beside a corresponding traffic road; and carrying out vehicle driving track backtracking on the freight visualization model. According to the invention, vehicle driving data are obtained through a truck-mounted satellite positioning system, and the data are stored in a time sequence database. A deep learning LSTM model constructs a network to train a congestion prediction model based on a time sequence, and a congestion index threshold value is set for user reference. In addition to the congestion index, the target vehicle route and the congestion index of each road section of the route in the time range can be obtained according to the license plate number and the vehicle running time interval, and decision support is provided for route optimization. Meanwhile, vehicle track backtracking is constructed, and the specific transportation track of the vehicle can be displayed and inquired in real time.

    本发明提供一种基于WebGIS的城市货运可视化方法及系统,其中方法包括:采集车载卫星定位系统中的城市货运车辆数据;训练拥堵指数预测模型,预测货运可视化模型中不同交通道路的拥堵指数;将分级结果标注于对应交通道路旁;在货运可视化模型进行车辆行驶轨迹回溯。本发明通过货车车载卫星定位系统获取到车辆行驶数据,将数据存储在时序数据库中。深度学习LSTM模型构建网络训练基于时间序列拥堵预测模型,设定拥堵指数阈值供用户参考。除拥堵指数外,本发明还可根据车牌号、车辆运行时间区间,可以获得该时间范围内目标车辆路线及其路线各路段拥堵指数,为路线优化提供决策支持。同时,构建了车辆轨迹回溯,可以实时显示查询车辆的具体运输轨迹。
