Map Matching Algorithm of Large Scale Probe Vehicle Data

Map matching is the key problem of probe vehicle technology.For the characteristics of probe vehicle data,traditional navigation map matching can not serve the requirements of probe vehicle data.Based on the common and different points between the map matching of traditional navigation and probe vehicle,the solution of probe vehicle map matching modes and corresponding road network structure have been proposed and the map matching algorithm system has also been promoted,including road first map matching mode,parallel reverse road map matching mode,node map matching mode and delay map matching mode.In addition,the algorithm has been verified and evaluated.The map matching algorithm promoted in the paper has been applied in the ITS demonstration project of Guangzhou and the practice has proved that it is quite effective and practical.
