Research On Coordinated Development Between Urban Traffic System And Urban Spatial Structure Of Changsha City

The coordinated development between urban spatial structure and urban traffic system was studied in Changsha based on the theories of urban geography, urban planning, informatics, space syntax, GIS etc. The main research results were as follows:In ancient times, the urban was developed mainly on the east of Xaing River. The style of urban road system was irregularly grid and the structure of city layout was a rectangle. In the recent and modern times, with the development of transport, the urban scale expanded quickly. The road network was not suitable for the modern urban spatial structure, because the spatial structure of Changsha was developed from the ancient city.an opportunity was provided to solve the problem between urban spatial structure and urban traffic system due to the construction of subway. Based on the theories of space syntax and GIS, the traffic accessibility of Changsha subways planning was studied. The construction of subway was suitable for the mono-centric urban model, and the coordinated between city groups relatively weak.The spatial development mode of Changsha was multi-center structure, but nowadays, the spatial structure of Changsha was square grid and radiation system. So the divorce between traffic planning and urban spatial structure will let the urban development fell into a dilemma. On one hand, these area that the traffic problems is not convenient will become more crowded, on the other hand, the lack of traffic facilities area will not have favorable traffic service.According to the research about coordinated development between urban spatial structure and urban traffic system, then present related suggestion and solution about this problem, as well as offers references for future urban development, planning management and decision-making.
