Abstract：Traffic is the lifeblood of economic development, and the road network accessibility is an effective evaluation index to measure the level of traffic development. This paper mainly based on vector data of road network of all levels from Land and Resources Bureau of Shaanxi province, used network analysis, spatial auto-correlation and geographically weighted regression as major methods to assess the level of road network accessibility. Furthermore, we also adopted the sub-item assessing and the comprehensive assessing in order to analyze the level of road network accessibility. Finally, the optimization suggestions were put forward according to the local conditions. The results show that: 1）The overall accessibility level of the road network in Shanyang county shows a "coreperiphery" differentiation structure characteristic of high accessibility in the north and low accessibility in the south, and decreasing from the high accessibility in the north to the periphery. 2) The high-access zone, mainly in the heartland of the research area, is the economic, political and cultural center of Shanyang county with flat terrain and convenient traffic, which has effect on its surrounding villages and towns to some extent. 3) The road network access level has a certain impact on economic growth, and the impact of each sub-item in different zones have spatial heterogeneity.
