The invention discloses a vehicle early warning system for an expressway epidemic area, and the system improves the vehicle positioning accuracy through the vehicle re-recognition technology, and can still precisely position and track a target vehicle through the vehicle body characteristics under the condition that the license plate recognition is difficult. 2, a vehicle user portrait library is established, and the historical travel traceability of the vehicle is realized; and vehicle trajectory restoration is carried out by fusing the multivariate spatio-temporal data, so that the problems of trajectory error, incompleteness and the like caused by ETC passing data missing can be solved. And the vehicle destination and departure time prediction is realized by using machine learning and deep learning technologies, and data support is provided for an epidemic prevention and control strategy of an exit station. A transmission private network is established by using the Internet of Things technology, and rapid transmission and sharing of the information of the epidemic-related vehicles are realized. The intelligent epidemic prevention and control equipment realizes real-time pushing of epidemic information and decision support of epidemic prevention and control personnel.

    本发明公开高速公路疫情地区车辆预警系统,系统利用车辆重识别技术提高了车辆定位准确度,在车牌识别困难的情况下仍能利用车身特征精准定位追踪到目标车辆。2、建立了车辆用户画像库,实现车辆历史行程溯源。融合多元时空数据进行车辆轨迹还原能够解决由于ETC通行数据缺失造成的轨迹错误、不完整等情况。利用机器学习、深度学习的技术实现车辆目的地、出站时间预测,为出口站点的疫情防控策略提供数据支撑。利用物联网技术搭建传输专网,实现涉疫车辆信息的快速传输共享。疫情防控智能装备,实现涉疫信息的实时推送和疫情防控人员的决策支持。
