Analysis of traffic comprehensive advantage based on GIS
—a case study of Yangtze River Delta
Abstract: It takes the Yangtze River Delta as the study area, which can be pided into 72 basic research unit and builds a multidimensional index system, doing an analysis by using the technology of GIS from the density of road network, the effect of the traffic trunk line and the advantage of the location, giving a comprehensive analysis of its traffic advantages, and also discussing the spatial distribution pattern and characteristics of the Yangtze river delta integrated transportation advantage and its forming factors. The results of the research are as follows. (1) The road network density of the Yangtze river delta region ranks among the top, but there is a striking difference from the north to the south in it, high in the north and low in the south (2) The densest is in Shanghai and its neighboring kunshan .Taicang, Hangzhou and Ningbo. The regional comprehensive transportation along the Shanghai-Nanjing, and the Shanghai-Hangzhou, is of great convenience, which is getting worse from the area towards north and south .(3) The spatial pattern of the location advantage takes on the center - periphery characteristics. There is a most highest location advantage in Shanghai and its neighboring areas, which declines from the center to the surrounding (4)The traffic space distribution pattern of the Yangtze river delta region makes a clear distinction from the north to the south, the north being better than the south. Shanghai and its adjacent areas have an advantage over other regions in transportation. The shanghai-Nanjing and shanghai-Hangzhou expressways, and the region along the Yangtze river in terms of transportation is second to Shanghai and its adjacent areas and the edge of the southern and northern area is poorer. Finally, a suggestion is put forward on how to make full use of different geographical units such as traffic advantages and avoid disadvantages. Suggestions and countermeasures lay a foundation for the regional economic development, industry selection and spatial structure optimization and provide support for the development of the Yangtze river delta region and the safeguard function.
