| Abstract: | The ability of obtaining vehicle location is the key factor that affects the performance of the car navigation system, but the traditional systems did not do very well in this aspect especially for operating speed and accuracy. In this paper, the map matching algorithm and the digital map processing are proposed to solve the problem. Results show that combined with the processed map, the proposed algorithm can significantly improve the matching speed and accuracy. |
