The Entirely Accessibility Analysis of Highway Network in Jinggangshan Scenic Region
研究了井冈山风景区公路网络的可达性，考虑地形、道路等级和拥堵因素，发现景区可达性呈中心-外围模式，旅游季节影响显著，并提出了改进建议。
This paper uses the accessibility analysis method to research the spatial structure of Jinggangshan scenic region, and take the factors which have important influence on speed, such as terrain, grade of road and congestion into consideration. Then we use the index of weighted average travel time to analysis the accessibility of road way out and the accessibility of scenic spots at different tourism season. The research results are as follows: Firstly, the accessibility of scenic spots presents the Center- Periphery pattern; the accessibility of road way out presents the East- West pattern.And they all follow the features of spatial attenuation, traffic directional and high-grade road directional. Secondly, tourist season has significant influence on the level of the accessibility. In tourist season, the accessibility changes obviously.Lastly, the highway network structure, the distribution of scenic spots and the scale of node are the important factors affect the level of accessibility. Based on the results, we propose some recommendations to improve the level of accessibility.
