Abstract :
Introduced in this paper is a land-based automatic vehicle location (AVL) expert system in the city and the suburbs environment of Beijing, China. Some issues about the data structure and graphic display are taken into account. A variety of expert knowledges and rules are stored in static or dynamic data bases for applications. A* algorithm is applied to determine the minimum cost route between the start and goal nodes. An example on route finding is given to show the effectiveness of A* algorithm. The route guidance functions are discussed in some detail. It is shown that the expert system of AVL developed in this paper is successful
