基于 GIS的南通市公路交通网络可达性研究
Road Transportation Network’ s Accessibility in Nantong City Based on GIS
摘要
Abstract
Using GIS network analysis extension module and based on the weighted average travel time index , the accessibility of highway traffic networks in Nantong both inside and outside was analyzed .The results showed that the internal accessibility in Nantong presented some irregular circle distribution ,the accessibility of central region along the Yangtze river was high and both ends of the region was low .Accessibility center appeared in the city center and extend-ed towards Tongzhou district , being consistent with the space development direction of the city center , accessibility of nodes was closely related with its economic location while that of inside area was little effected by the highway .For out-side accessibility , after the Sutong bridge and Chongqi bridge were built , the weighted average travel time was short-ened to 2 hours from each Nantong internal node to three cities such as Shanghai , Suzhou and Wuxi , especially in Qi-dong, accessibility of outside area reduced 0.79 hours.The spatial pattern of outside accessibility was characterized by the fact that accessibility of southern region centered by downtown area , Tongzhou and Haimen is high while that of northern region is low .关键词
