Abstract. Map matching is the most basic problem of  integrating GPS with GIS. 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 points and the front two points. The probe- vehicle points are located one by one through the algorithm. The matching method can resolve both the flutter in parallel segment and the mistake match in intersections. The method also considers the disadvantage of the point to line and the advantage of the line to line, and it can guarantee the speed and accuracy.

Keywords: probe-vehicle; matching algorithm; parallel segments; intersections
