Aiming at the problem of route planning of large region,this paper discusses the establishment of road hierarchical divided model and multi-scale road networks database. Then it brings forward the method of constructing multi level road networks topology. Finally,it selects an optimal route by using Hierarchical Spatial Reasoning and ameliorated heuristic A arithmetic.
