The Research On Commercial Facilities Layouts Of The Transfer Space Of The Underground Railway Station

Since the rapid development of domestic urbanization and the generation of metropolitan area, people’s travel demands have increased dramatically. With the widespread popularity of sky trains and high-speed rail, the time for long-distance passenger transport has diminished significantly. By contrast, the highway network requires higher technology cost and more infrastructure facilities, together with a large volume of passengers decentralizing costs in order to form economy scale. Consequently, the main stream of modern design has turned out to be the mega-structure and synthesis in traffic architecture. The emergence of the traffic complex in megacities enables the traffic nodes to be distributed in a more intensive way, which overtakes the traditional small-scale stations in terms of the capacity of enhancing the cityscape and relieving the peak times of passengers on a large scale. The problem lies in the impractical condition to construct the complex in the first-tier cities, the land prices of which are extremely high. If the station is located in the suburb, business passengers’ time consumed on the way from central districts in the cities to the large station in the suburb can even exceed the transportation time between the regions. Taking the above two points into consideration, underground railway station has risen in response to satisfy the demands of the short-distanced business routes with intensive passengers in first-tier cities.Compared with the traditional flow of long-distance passengers, business commuters, travelling middle-short distance, require higher time cost. This kind of passengers is short of time for packing their carry-on luggage carefully, resulting in a higher power of impromptu consumption. The transfer space, in the underground railway station, is the main gathering area for the high-consumption group, which makes this area possess large and extensible business capacity. Chapter One and Two, through the analysis of development theories in relevant cities together with economic and social benefits, demonstrate the potential of the underground railway station and the rationality and necessity of the commercial exploitation for the transfer space. Chapter Three and Four, on the basis of the on-site survey of the underground railway station under construction in China and the questionnaire aiming at the target groups, combining with cases both domestic and abroad, summarize the main characteristics of passengers and the difference of moving routes, both in underground railway station and traditional stations; and also give projected analysis on the effects of the commercial layouts in the underground railway station. Chapter Five mainly focuses on the coupling relationship between the transportation space and the commercial space in the underground railway station, through the data collecting from the questionnaires, analyzing the subjective sensation of passengers; the objective classification of the practical cases both domestic and abroad, relying on the antlogic software to carry on the simulations based on the survey data, then optimizing the results from the simulation process. Ultimately combining the analysis results from Chapter Three to Five, the commercial layout strategies, appropriate for the transfer space in the underground railway station, have been summarized, which are as follows, the flow restriction of the commercial passage, the reduction on the border business, more uses of independent and open commercial districts; and also attempt to provide a reliable thinking for the design of commercial space in relevant architecture. Meanwhile, it is expected to "promote work in all areas by drawing upon the experience gained on key points", taking an initial exploration about lessening the urbanization contradiction and improving the urban structure from the perspective of architectural design.
