The Subway Station And The City "Transition Space" The Use And Optimization Research

Relevant researches of domestic and foreign shows that the subway system is gradually becoming the main means of transportation for residents in major cities.At present,the follow-up wave of domestic subway construction is becoming more rational with the country's macro-control.Zhengzhou,as a new National central city in the middle of the country,has established itself in the subway declaration and construction sequence by its own advantages.However,the contradiction and problems between the subway station and the urban space are also constantly being highlighted,which needs to be resolved.In this context,based on the objective facts of the development of Zhengzhou city and subway,by literature analysis method,comparative research method,case investigation method and the combination of qualitative and quantitative methods,this paper takes the urban space of Zhengzhou subway station and the city's “intersection space”,which within a certain range(this paper refers to the radius of 400m)around the subway station as the research object,and designs in the urban space.The layer summarizes its basic characteristics,research points and influencing factors,and summarizes its existing utilization problems through case studies combined with TOD and other related theoretical types.In order to enhance the vitality of the “intersection space” and promote the coordinated development of the subway system and urban construction,the optimization principles and optimization objectives are proposed in combination with relevant theories and cases,and the “space” of Zhengzhou subway station and city is proposed based on the problem-oriented classification.Optimize design strategies.The main results of the thesis are as follows: Firstly,the concept of “intersection space” is proposed,and combined with relevant theoretical research and Zhengzhou objective facts,it is defined as the urban external space within 400 m radius of the subway station;Secondly,the main points of the relevant literature theory of subway and city are summarized,and the guiding significance of this paper is summarized by type;Thirdly,the city and subway lines 1 and 2 of Zhengzhou are summarized.The basic characteristics and research points of the “space” between Zhengzhou subway station and city are analyzed and summarized;Fourthly,the paper is to conduct an overall spatial cognition analysis of the “space” between Zhengzhou subway station and city through qualitative and quantitative research methods,summarizing its influencing factors,and formulates the standards of analytical the problem with TOD and other related theories,and on the architectural design level of urban space,the status quo of 18 typical cases in Zhengzhou is investigated in terms of physical form traffic parking,public space,facility signs and use activities,and summarizes the utilization problems of the “space” of the residential community type,commercial center type,transportation hub type,rest-type subway station of Zhengzhou;Fifthly,the paper develops optimization principles and strategies with the problem above,TOD and other related theories,and proposes specific optimization strategies for four types of the “space” of Zhengzhou in the architectural form,traffic parking,public space and facilities signs.
