  • Based on the principle of the shortest path algorithm in graphic theory, this paper described the optimal path solution in practical urban road network, which includes traffic control signal. The characteristics of road network with restricted routes were analyzed, the corresponding mathematic model was constructed to convert it into another road network with free routes. The relationship of road network joints was expressed, the traditional Dijkstra algorithm was optimized by dynamic adjacent node relation matrix and adjacent node weight matrix, the corresponding algorithm was constructed. A vehicle guidance system was developed with the optimized Dijkstra algorithm to find the optimal routes in the network. The results indicate that the system can reduce the computation nodes of road networks.
