The invention relates to a path fitting method based on an ETC portal frame in the technical field of traffic information. The path fitting method comprises the following steps: acquiring informationof passing vehicles through each acquisition terminal device arranged in a highway network; transmitting the collected information to a background data processing center through a network channel, andprocessing; screening to obtain an effective vehicle data set; carrying out fitting processing according to time and places; marking the passing points on a GIS map; remotely connecting an inspectiontracing module through a network; and after the vehicle passing data information in a storage database is called, graphically displaying the vehicles and passing information needing to be traced by connecting to a passing information display module. According to the ETC portal frame-based path fitting method provided by the invention, basic data acquisition is rapid and complete, vehicle drivingpath calculation is accurate, and annotation display is vivid and intuitive.
本发明涉及交通信息技术领域的一种基于ETC门架的路径拟合方法,首先通过公路网中布置的各个采集终端设备采集获取经过的车辆信息;采集的各信息通过网络通道传输至后台数据处理中心进行处理;然后筛选获得有效车辆数据集;然后按时间及地点拟合处理;在GIS地图途经点标注处理;通过网络远程连接稽查追溯模块,在调用到存储数据库的车辆通行数据信息后通过连接到通行信息展示模块以图形化显示所需追溯的车辆及通行信息,本发明能够提供一种基础数据采集快速齐全且车辆行驶路径计算更为精准,标注展示更形象直观的基于ETC门架的路径拟合方法。
