| With the development of China urbanization regional linkages have been promoted.Therefore,the design of intercity railways has attracted attention.The construction of inter-city railway stations on passenger dedicated lines is the future development trend of inter-city transportation.However,how to interact with intercity railway passenger flow and subway passenger flow requires attention to the transfer function of the station design.At present,research on interchange space design is mostly focused on subway stations or integrated passenger terminals.The design of the interchange space at the station where the intercity railway line and the subway line connect is still in the exploration period.Whether the current status of the transfer space model,the organization of the transfer flow line,and the division ratio of transfer function areas can meet the transfer needs remains to be verified.Therefore,the research on the space design of the existing intercity railway station to subway transfer should be strengthened.Exploring the problems that may arise in their space design,finding bottlenecks and resolving them through optimization of design strategies,It will provide some basis for the future design of the interchange space of intercity railway stations to subway stations.This article defines the concept of the intercity railway station and its transfer space firstly.Differentiating intercity railway stations from passenger hubs that have been connected to intercity railway lines in the past.Since the continuity of the transfer process,the transfer space studied in this article is also different from the narrow "connection space" between two different stations.Based on the previous basic theoretical research related to the transfer space design,the influencing factors of the transfer space design in this paper are determined as the three major factors of transfer space organization,transfer passenger flow characteristics,and capacity of transfer equipment facilities.According to different transfer organization methods,three cases were selected for transfer analysis on the same station,station hall transfer,and channel transfer.During the survey process,the capacity of the transfer equipment in the station was measured by issuing questionnaires and on-site observations.Through software simulation analysis,the transfer bottlenecks of the survey sites were found.Finally,based on the three major factors listed above,the author proposes an optimization strategy for the organization of the transfer space—the ratio of the transfer function—the layout of the transfer facilities one by one,and designs the transfer plan based on the optimization strategy,and simulates it with software.Display the resolution of bottleneck points to verify the effectiveness of the optimized design. |
