Abstract

Based on Network Analyst extension of ArcGIS,the road network dataset model in Hunan province was established in the paper.Choosing weighted mean travel time as indicator,this paper evaluated the spatial structure and evolution of major cities highway accessibility in Hunan province.The results showed that the changing rate of accessibility value decreases from the east part to the west-south part at the first stage,but takes on multi-core pattern at the second stage.The result of research would provide a scientific reference to improvement of local road network.
