Based on the application of integration of GPS and GIS used in traffic direction system, the principle and characteristics of the mapdata organization, the satellite fixed position constitution in the system are discussed. Using the Dijkstra shortest path algorithm,the searching path is optimized. It deals with some avoid points, that is when searching for the shortest path, avoid points can be neglected. At last, the station that start point and end point both in the route are processed, that made start point, end point and avoid point can be chosen from points which between routes. A got good result obtained in the actual application.
