Research On The Optimization Design Of Space Sign System Of Xi’an Metro Transfer Station

With the continuous construction of the three-dimensional rail transit system with the rapid development of the city,the urban metro planning has long been woven into an underground transportation network instead of a single line.The metro is the blood connecting all regions of the city,and the metro transfer station is an important vein node.At the same time,the number of transfer stations also increases exponentially with the continuous opening of metro lines.The complexity and diversity of metro transfer station environment make it necessary to study its internal spatial structure,streamline organization and the design of guidance system required by passengers during transfer.The metro guidance system is in a weak position in the current rolling metro torrent.The confusion of metro transfer station space is followed by the unsystematic,discontinuous,incomplete and unclear guidance design,which leads to the slow understanding and cognitive deviation of passengers,thus reducing the transfer efficiency and causing the social reflection of passengers such as "difficult to find the way","large flow","patching","advertising" and "standardization",which can not meet the increasingly high requirements of urban metro users for metro image.Based on the above problems,from the perspective of environmental psychology,combined with cognitive science,semiotics and other relevant theories,this paper focuses on how the guidance system in the space of Xi’an metro transfer station can better "find the way" in the underground space.Secondly,through the field survey,follow-up survey and questionnaire survey of Xi’an metro transfer station,it makes careful records,research and analysis.After summarizing the "three-dimensional guide and transfer information integration" strategy of optimizing the content of Xi’an metro,and then combining the "three-dimensional guide and transfer information integration" of domestic and foreign metro stations,this paper puts forward the "four-dimensional guide and transfer information integration" strategy of optimizing the content of Xi’an metro.Finally,it explores the optimal design scheme of the guidance system in Xi’an administrative center.The research results of this paper hope to optimize the guidance system for Xi’an metro transfer station,improve the underground path finding environment,give passengers a better ride experience,and feel the coexistence of the cultural charm of Xi’an’s Millennium ancient capital and the modern flavor of the international city.
