摘要
介绍一种基于短周期(1s间隔)的将探测车采集的道路交通数据——GPS数据转换为GIS电子数据的方法(简称为采集方法),主要包括坐标转换、地图匹配和道路交通信息统计。通过对GPS点进行跟踪匹配,可以准确地将GPS点匹配到各个路段上,从而获得准确的交通数据。
A method of collecting transportatiOn data based on ls interval GPS data and GIS electronic map was introduced. This method included three parts: transformation of WGS84 coordinate, map matching, and transportation data statistics. Through vehicle tracking map matching method, GPS point can be precisely put on the road section, and accurate transportation data can be collected.
