The invention provides a congestion early warning method and system applied to intelligent traffic. The method comprises the following steps: acquiring traffic data by deploying an electronic license plate system, integrating GNSS acquisition equipment and using a video monitoring system; 2, the actual speed of a vehicle is calculated through GNSS data collected by GNSS collection equipment, the average traffic flow density is calculated based on an electronic license plate obtained by an electronic license plate system and video data obtained by a video monitoring system, and real-time traffic flow statistics is conducted by integrating the electronic license plate, the GNSS data and the video data; 3, identifying traffic congestion routes in the road network based on a traffic flow analysis method to obtain a traffic congestion route set; and step 4, performing early warning based on the traffic jam route set in the step 3. According to the invention, the method can better adapt to personalized demands, provides more accurate congestion information, provides more comprehensive, real-time and personalized traffic early warning service for users, and effectively alleviates the limitation of a conventional method.

    本发明提出了一种应用于智慧交通的拥堵预警方法及系统,包括:通过部署电子车牌系统、整合GNSS采集设备和使用视频监控系统获取交通数据;步骤2:利用GNSS采集设备采集的GNSS数据计算车辆实际速度、基于电子车牌系统获取的电子车牌和视频监控系统获取的视频数据计算平均车流密度,综合电子车牌、GNSS数据和视频数据进行实时交通流量统计;步骤3:基于交通流量分析方法识别道路网络中的交通拥堵路线获取交通拥堵路线的集合;步骤4:基于步骤3中的交通拥堵路线的集合进行预警。本发明能够更好地适应个性化需求,提供更精准的拥堵信息,为用户提供了更全面、实时且个性化的交通预警服务,有效缓解了传统方法的局限性。
