Research On Complex Design Strategy For Entrance Space Of Rail Transit Complex

With the development of low-carbon city,the number of rail transit is increasing significantly for enhancing the convenient life of urban residents.The entrance space of a rail transit complex is an important linking station,complex and urban space,showing a highly inclusive and complex feature.However,research on entrance space is ignored in the current academic field,and it is often classified into public space,traffic space and so on.Scholars often study from a single perspective,such as transportation,transfer,thermal comfort,humanization and so on,lack of systematic research from the overall perspective.The purpose of this paper is to explore the complex system of entrance space of the influential factors.At the same time,it absorbs the excellent construction experience at home and abroad,and puts forward the compound design strategy.Firstly,this paper clarifies the current situation,functions and characteristics of the entrance space of the rail transit complex through the study of domestic and foreign documents,and then forms a preliminary understanding.Secondly,it analyzes the complex mechanism of the entrance space and clarifies the research logic: exploring the elements that need to be "recovered" and the mode of "combination".Based on the grounded theory,this paper proposes the composite influencing factors of the entrance space of the rail transit complex,and clarifies the three key factors to be composited: functional factors,traffic factors,and environmental factors.Thirdly,it conducts field research on three key elements.A total of 5 entrance spaces of typical rail transit complexes at home and abroad are selected to compare their current elements and explore the advantages and disadvantages of existing composite models.Finally,it proposes a composite design strategy for the entrance space of the rail transit complex.In terms of function,this paper proposes 5 common styles and 3 composite modes.Different composite modes are adopted for different styles to create a diverse and efficient functional space.In terms of transportation,4 types of entrance core modes and 3 types of spatial optimization directions are proposed according to the composite streamline organization form.In terms of environment,the composite design strategy is proposed from three aspects: integrating the basic environment,embedding in special spaces,and combining humanized facilities.With the rapid development of rail transit in China,the integrated construction of "sites,cities,and people" has become the core of the development of rail transit complexes.The entrance,as a key node for the integration of "sites","cities" and "people",has new connotations in terms of roles,forms,functions,flow lines and so on.This paper conducts a systematic study on the entrance space of the rail transit complex.It clarifies the complex development trend and mechanism of the entrance space.Based on the needs of the crowd,a composite influencing factor system of the entrance space is proposed.At the same time,this paper conducts field research to compare the composite elements.Learn from each other’s strengths and propose a composite design strategy for each element.This paper has theoretical significance and practical value for the development of entrance space of rail transit complex.
