| 摘 要： | 本文以ArcGIS软件的空间网络分析模块为主要技术手段,采用加权平均旅行时间为主要指标,对不同阶段湖南省区域的公路交通网络可达性进行定量测度与分析。研究表明,20世纪80年代以来湖南省可达性水平由长株潭地区为中心向外围呈圈层式优化之势,可达性值变化率呈多级格局,可为进一步优化区域交通网络提供参考。

| 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. |
