Abstract

Abstract

The modeling method of inter-town guide signs based on road network topology was discussed, the concepts of guide sign items were proposed, and the state functions of guide signs were given.Three intersection functions, such as adjacent node set, node-arc angle set and connected node set, were presented, and based on the shortest path method proposed by Dijkstra, a road guide sign model was built by using the intersection functions.The main idea of the model was as follows: destination city was taken as searching center, road guide signs were deployed by searching the adjacent node set of intersection in the influential region of the city, every path designated by road guide signs was an optimal one.Example analysed result shows that the road guide signs created by the model can effectually guide road users to aims.
