Regional Impaction and Evolution of Expr ess Way Networks in China

With the development of express ways, they has became the main transport model of road system, affecting the development of social-economy and urban region.In this paper, based on the research history and progress in China, the author analyzed the spatial evolution course of express way networks in China, which have the slowness development(1988~1997) and quick development stage(1997), and discussed their spatial organization models, including regional access, urban circle road, access between hub cities, urban interior road, and travel road. Furthermore, by designing the shortest time model and O-D matrix, the author analyzed the regional impaction of express way networks in detail. Firstly the evolution of traffic flow structure in China was discussed, which enlarged the transport distance of road system and actuated the traffic to concentrate in the East region of China. Secondly, the author analyzed traffic flow structure of urban regions and its region system, which emerged as the main traffic flow access and hub-and-spoken system in Yangze delta and Pear river delta urban regions and Thirdly, the express transport circle of 30M and 1H around province cities were discussed and drew the conclusion that express way enhanced their service scope and accelerated concentrating speed of population and products to province cites.
