Research On Walking System Node Space Design In Rail Transportation Hub Complex

Along with the rapid development of rail transit,rail transit hub complex has emerged rapidly in big cities of China.And it is an important construction project in major cities.Traffic transfer is the most basic function in rail transit hub complex.Pedestrian system is the main contact medium in various transfers,and it is also an important deciding condition for the public space to work well.With the diversification of functions in the complex,pedestrians tend to be more complex,especially in the walking system nodes,there are not only complex traffic and transfer passenger flow,but also other urban life other people.Therefore,we should not only pursue fast and convenient traffic transfer efficiency,but also create a comfortable and pleasant space environment with high quality.This will have the contradiction or conflict in demand,then also care for this or lose that.So,how to balance two different needs in node space needs further discussion.Because of the late start of the construction and development of the rail transport hub complex in China,there is a widespread problem of low transport transfer efficiency and low spatial environment quality,which needs further improvement.The space of node properties in rail transit hub system has received little attention,and little research has been done in this area.Therefore,the research topic of this paper is put forward.In view of the contradiction between the requirements of two kinds of human flow in the above node space and the existing problems in the status space,this paper mainly discusses the space of this kind of node from two aspects: first,to improve the transport and transfer efficiency of the node space by improving the orientation of space and organizing the layout rationally,and the second,to improve the environmental quality of node space through perfection Optimize environmental facilities and create theme characteristics.In addition,we should strengthen the relationship between nodes to form an organic and integral walking space.The framework and contents of the article are as follows: the first chapter is "asking questions".Based on the development background and existing problems,the research topic is put forward under the premise of combing the research status at home and abroad.The second and third chapters are part of the analysis problem.The second chapter,summarizes the basic theories,and analyzes some excellent cases,based on understanding the basic concepts.In the third chapter,the current problems,components,spatial characteristics,spatial design requirements,design factors and development trends of the node space in the rail transit hub are analyzed.The fourth chapter is the "problem solving" part.Because of design objectives and design principles,the corresponding design points are put forward based on the analysis of the preceding chapters.The fifth chapter is the part of "empirical study".According to the design points proposed in this study,taking the node space of the Beijing Xizhimen rail transportation hub complex as an example,the improvement design is carried out to verify the reasonableness and feasibility of the conclusion.
