Study On Short-distance Traffic Link And Spatial Adaptive Design Strategy Around City Rail Transit Station

Urban rail transit is under rapid development in China nowadays.While the density of station distribution in most cities is distinctly much lower than the cities in developed countries or regions.Moreover,due to the expansion of urban built areas and the weakness of short-distance traffic link,amounts of people cannot benefit from the rail transit well as a matter of fact——Efficient short-distance traffic assisting rail transit becomes necessary.However,the integration of rail transit and short-distance traffic in China is still underdeveloped,and promblems have also pointed to the environmentsensitive link space between the two.Short-distance traffic puts new demands on space because of its development features such as targeted and timeliness,as well as its technical features such as high frequency and small tools.Therefore,for higher efficiency and usage rate of public transport resources,the public space response research and practice towards the shortdistance traffic link around the stations is the next key point.This thesis takes the "Background research","Object analysis","Association establishment","Method and strategy" and "Research application" as the research route:The first chapter takes the last one-kilometre problem of urban transportation as the starting point,defines the research object and category,and presents the development picture of the project through a review of domestic and foreign research and current status;In chapter two,Based on the researches on the density of station distribution and short-distance public/sharing traffic link status quo of urban rail transit in world representative cities,the thesis outline the main application scenarios and new space requirements for short-distance transportation;The third chapter summarizes the hierarchy of short-distance traffic link requirements,from the aspects of capacity matching,link efficiency,link security,and operation continuity,the public space responsive mechanism under the demand of related traffic in urban microcosmic and medium scales is studied.The fourth chapter summarizes the connotation relationship of multi-modal traffic convergence space integration and the type of convergence facilities.On the basis of the short-distance public /sharing traffic link,"station-walk-vehicle " integrated responsive system spatially supported by the "route-exit" mode around the station is initially established.And based on demand and problems,strategies from seven aspects are constructed.Thereafter,the "public-sharing-individual" traffic hierarchy can be realized,and the range of the comprehensive influenced urban realm around urban rail transit stations is supposed to be expanded.The fifth chapter discusses related practice through domestic and foreign case studies,and combines analysis and application of Chongqing Metro Line 1 College City Station.
