Research On Traffic Facilities Planning Of High-Speed Railway Hubs In Small And Medium-Sized Cities

Nowadays,China will comprehensively promote the construction of the “eight vertical and eight horizontal” high-speed railway network,and has already entered the “high-speed rail era”.In the wave of construction and development of high-speed railway hubs,small and medium-sized cities have also ushered in new opportunities and development space,but inevitably face many pressures and challenges.Due to the small scale and attractiveness,and the low level of urban infrastructure construction,there are often problems such as low efficiency of distribution and traffic chaos in hub areas.Therefore,while the construction of large-scale high-speed rail transportation hubs is gradually maturing,the rational,scientific and local planning of high-speed railway hubs in small and medium-sized cities is a problem worthy of consideration.Based on this,this paper analyzes,explores and summarizes the planning contents of high-speed railway hubs in small and medium-sized cities from four aspects: function of hub,passenger flow of hub,distributing road network and hub facilities.Firstly,this paper discusses the characteristics and functions of high-speed railway hubs in small and medium-sized cities,and discusses the interaction between high-speed railway hubs and urban development in small and medium-sized cities,including the location relationship with cities and the location of hubs.Etc.,and summarizes their development and planning goals.Secondly,influencing factors and impact results of passenger flow of high-speed railway hubs in small and medium-sized cities are discussed.For the forecast of external passenger flow,total external passenger flow of the small and medium-sized city hubs and the external passenger flow of the multi-rail hubs are analyzed combined with the case analysis,and the consideration is proposed based on the ride rate method.For the forecast of transfer passenger flow,two prediction methods based on the traffic distribution principle and traffic mode division are given.Thirdly,this paper defines the hierarchical connotation of the distributing road network of small and medium-sized cities,and analyzes relevant connection methods and gives optimization suggestions through cases.Typical hub network layouts of small and mediumsized cities are summarized,and an analysis of the adaptability for different location hubs is given.This paper also introduces the typical form of hub access nodes,and gives case introduction and adaptability analysis of small and medium-sized cities.Finally,the spatial layout mode and the layout of plane function of hub facilities are analyzed and discussed,and the common modes of small and medium-sized cities are given.In addition,the station buildings,connection facilities,hub channel and transfer information are explored,and the common design forms of small and medium-sized cities are given.The specific layout mode of the hub facilities of high-speed railway hubs in small and mediumsized cities is summarized,and its adaptability analysis is given through cases.
