Research On The Rationality Of Traffic Facility Layout In Large High-speed Rail Hub Based On Transfer Efficiency Evaluation

For a long time,China’s high-speed rail hub will still show the characteristics of "transport node" as the main function.With the development of social economy and awareness of the hub,the high-speed rail hub is developing from the extensive exploration and rapid,large-scale construction period to an optimization phase,paying more attention to the close physical and logical connection between the high-speed rail and various connecting transportation means,as well as the seamless connection in passengers transportation,emphasizing the implementation of the "people-oriented" concept.Generally speaking,the planning and construction of high-speed railway hub is a process of continuous summary,exploration and gradual improvement.A certain period In the future will still be a strategic opportunity for China to promote the scientific construction of high-speed railway passenger transport hub.It has become an urgent issue for planners,designers and managers of China’s highspeed rail hub in the near future to summarize the past experience in connection planning,construction and development of China’s high-speed railway passenger transport hub,as well as to maximize the effect of connection and transfer services of the hub,through the scientific and reasonable layout of transfer facilities in the future hub construction practice.Therefore,this paper focuses on the study of the rationality of the existing largescale high-speed railway hub transfer facilities layout mode,which could minimize the transfer distance and improve the transfer efficiency of hub passengers,and fundamentally analyzes the reasons for the uneven spatial layout and transfer service effect of China’s high-speed railway hub.It is of great theoretical value and practical significance to promote the scientific process of planning,construction and management of integrated high-speed railway junction in China.The thesis consists of the following parts:First of all,starting from the relevant concepts and functional orientation of highspeed railway hub,the research scope of transfer is defined.On this basis,the basis of hub scale division is determined,the large-scale hub is selected as the research object of this paper,in addition,the key research transfer facilities are defined,and the transfer characteristics of passengers in the core area of the hub are systematically analyzed.Secondly,the paper expounds the contents and basic principles of the high-speed railway hub transfer facilities layout,which provides the basis for the following statistics,evaluation methods and analysis ideas,and summarizes the hub overall layout mode based on the distribution of the intensive degree of the hub station facilities layout,as well as the connection and transfer mode between different transport means and the highspeed railway passenger station.And the paper puts forward the evaluation method based on passenger transfer efficiency to study and judge the rationality of hub transfer facilities layout,and introduces the correlation analysis method of hub layout mode and passenger transfer efficiency.Then,based on the above methods and ideas,the passenger transfer efficiency of the 12 large-scale high-speed rail hubs studied in this paper is statistically evaluated,and the influence mechanism of the hub layout mode on passenger transfer efficiency is explored through related analysis,to summarize and obtain reasonable and efficient hub layout models.And the paper puts forward specific suggestions for the reasonable layout planning of large high-speed rail hub transfer facilities from different levels.Finally,from appearance to essence,combined with the construction management practice,the paper fundamentally analyzes the reasons for the uneven connection and transfer effect of the high-speed railway hub in China,and puts forward suggestions for the relevant departments,so as to promote the integrated connection planning and construction process of high-speed railway hub in China.
