浮动车数据与电子地图的匹配方法研究

Map matching is the most basic problem of integrating GPS with GIS. At the same time, the efficiency and accuracy of matching algorithm directly influence the application of float cars. Regressive equation is established by the factors, such as perpendicular distance between the GPS point and the road segments, drive’s angle of float car, angles constructed by the post two point and the front two point. The probe-vehicle points are located through the algorithm one by one. The matching method can resolve both the flutter in parallel segment and the mistake match in intersections. The method also considers the disadvantage of point to line and the advantage of line to line, then it can guarantee the speed and accuracy.
