[Abstract]:In view of the advantages and disadvantages of the existing map matching algorithms, this paper combines the characteristics of vehicle navigation to mesh the spatial road data and establish the topological relationship, and improves the map matching algorithm of intersection. A map matching algorithm based on course vertical line is designed by making full use of course information. The advantages of the algorithm in solving the problems of mismatch, mismatch and low matching accuracy are verified by the actual data obtained by dynamic measurement. While improving the accuracy and accuracy of the algorithm, the speed of the algorithm can also meet the requirements of real-time navigation.
