4G无线探针在高速公路交通状态识别中的应用

Application of 4G wireless probe in expressway traffic status recognition

利用4G无线探针在高速公路上检测得到的数据,通过开发的系统软件,能够展现车辆行驶轨迹,从路线状况、行程速度、路段实时车速3个方面对路段的交通状态进行识别,并在地图上实时显示路段的道路交通情况。文章结合ETC、卡口视频等数据进行融合分析研究,通过统计算法、机器学习算法等,实现了对高速公路交通状态的识别与实际分析应用。

By using the data detected by 4G wireless probe on expressways and the system software developed,the vehicle trajectory can be displayed,the road traffic state can be identified from three aspects:route condition,travel speed and real-time road speed,and the road traffic condition can be displayed on the map in real time.In this paper,through statistical algorithm,machine learning algorithm and so on,the ETC and bayonet video data are analyzed and studied to achieve the expressway traffic status recognition and practical analysis application.
