Abstract
From the angle of the high relationship between the traffic organization and urban spatial structure, the geographic concept, coupling, was proposed in the article, and the coupling mechanism of urban spatial structure and traffic organization was studied primarily based on the analysis of the connotation of the coupling, and the coupling function of main associated factors between the urban spatial structure and traffic organization was analyzed.
Highlights
2009 nodes makes the leading traffic mode and urban spatial structure gradually form mutual supported state
2.2 Urban spatial structure decides the spatial distribution of the vested traffic mode and traffic network to large extents
The urban spatial structure is formed under the principle that the sites with different urban functions are distributed in certain space, and human traffic flow is the transfer in different functional sites
Summary
When the urbanization process develops to certain degree and the extension of urban scale achieves certain extent that the urban economic living can only be ensured by the traffic vehicles, the interior urban traffic system can be generated, and corresponding traffic vehicles will occur and gradually develop (Liu, 1998, P.78-83). The urban spatial structure is formed under the principle that the sites with different urban functions are distributed in certain space, and human traffic flow is the transfer in different functional sites. The urban spatial structure decides the flux, flow and mode selection of human trip, and further decides the mode composing of urban traffic and the organization base of traffic space. The change of urban functional allocation mode objectively requires the use of advanced traffic mode and the development and perfection of traffic spatial organization (such as the extension of bus lines, the increase of road net density and the perfection of infrastructure), and drives the change of the urban traffic organization mode. The spatial allocation of MRT stations will be largely influenced by the allocation of the nodes with large passenger flow in the urban spatial structure, and influence the line allocation of MRT
