A Study On The Space Efficiency Of Pdestrian System Of Rail Transportation Impact Realm In Urban Centeral Area

As a new implant in the city urban functions, the entrance of urban rail transportation will have many prent situations like uncoordinated,suited and even unreasonable with urban spaces after completion.Causes lots of unconvience for urban rail traffic users in daily use.Meanwhile the city center itself have the feature of function highly composite,high density,high volume of buildings.Under the circumstances, rail transportation will need to plan the acess space resonablely,improve the space efficiency of the pdestrian system in city center after intervention.For our special situation,China’s current urban centers for urban rail transit space research mainly concentrated in urban planning for spatial integration, the use of underground space, urban space development and other aspects of railway stations.The research relates many aspects, However, the impact is relatively small for railway station within walking space-efficient as a research point.The study objects to the city center pedestrian space-efficient system. The scope of study is the central area of the rail traffic influence realm.Researches the space-efficient in urban centers rail transport influence realm through theoretical literature, a variety of commonly used methods questionnaires, field research, case comparison, software simulation and so on. And take the research into practice and application in station of guanyinqiao of line 3 in Chongqing.The main contents are as follows:Characteristics feature research of city center pedestrian systemThesis selects series of practice cases of pdestrian system at home and abroad in city center,extract its concern for pedestrian behavior, handle the basic design methods and steps the city center pedestrian system.Then at last summarized the basic design principles of pedestrian system in the city center.Analyze on the factors walking space-efficientBased on the basic principles in city central pdestrian system design, involves the research of the rail traffic influence realm pedestrian space-efficient system. And summed up the index of impact of space-efficient, evaluate it with expert evaluation. At last, get the weight of each space-efficient evaluation index. Summed up the design principles for improving space-efficient by comparing the evaluation score of guanyinqiao and nanping in line 3, Chongqing.Design strategy in enhancing space-efficientEnhance the effectiveness of pedestrian space from two aspects:space capacity and the mobility in the space. Discuss specifically in design strategies in urban space capabilities, node scale, pedestrian flow lines and the space environment quality. And the four strategies will settle in economy-efficiency, social-efficiency and environmental-efficiency.Design methods practices of enhancing the efficiency of pdestrian systemBased on the previous research on existing, choosing some pratice projects for validation and application of the research results in Chongqing and Sichuan.To feedback, revise and improve combined with the actual research project.
