Lanzhou Rail Transit Railway Station Integrated Hub Project Planning Research

At present,major cities in China are building urban public transportation systems with rail transit as the main body.The integrated urban rail transit hub formed in this system is an important area for large-scale passenger flow distribution and transfer.Such hub projects are often formed first.The main place for the city's outward passenger transport is near the railway passenger station,so the rail transit station's comprehensive hub project has been formed.Rail transit train station hub gradually evolved from a more functional single traffic project to a large-scale comprehensive project with passenger flow exchange and different urban functions and transportation modes coexisting.To synergize the advantages of various modes of transportation and achieve the goal of the integrated development of modern urban rail transit hubs,it is necessary to scientifically integrate a variety of different modes of transportation.The integration will not only optimize the allocation of transportation resources and facilities,but also promote the full utilization of the city's functional benefits,especially economic benefits,in the hub project and surrounding areas,and further stimulate the vitality of the city.The rail transit station complex hub project in China is often lack of systematic planning due to inconsistency in the main construction and the lack of construction time sequence.The project construction is usually based only on the requirements of the current stage of its own project,and the project is designed for the transportation hub project.Poor considerations in terms of integrity and comprehensive utilization have led to a low degree of systematization between the transportation functions of the hub project,and there has been a disconnect between the development of rail transit and the transfer of other transportation modes at the station and the development of land use along the line.Based on the above factors,this paper takes Lanzhou Railway Station Reconstruction and Expansion Project and Lanzhou City Rail Transit Construction Project as examples to conduct a planning study on the integrated integration of Lanzhou Rail Transit Railway Station Complex Hub Project.First of all,it analyzes the functional zoning and layout modes of railway passenger transport hubs.By analyzing the functions and traffic organization of typical passenger transport facilities,the paper summarizes the spatial layout of passenger transport terminals,the layout of transfer facilities,and the construction and management of hubs.The main modes of traffic organization provide support for the types and scales of demand for various types of facilities that connect hub projects;then it studies the basic theories and basic models for the forecast of the traffic demand of the city's external passenger transport hubs,focusing on the analysis of the set of foreign passenger terminals.Forecasting traffic volume,forecasting the construction of transportation modes,and predicting the scale of supporting transportation facilities,and proposing a method for forecasting the scale demand of the main function area and transfer facility functional area,focusing on the traffic organization and transfer service objectives of the integrated passenger terminal station area.Followed by the study of the planning and design of the connection facilities of the hub project,through the analysis of the characteristics of the passenger transfer requirements and the characteristics of the connecting facilities,then the reasonable scope of impact and the prioritization of the connection methods are obtained,to lay the foundation for the layout planning of the hub engineering connection facilities and the vertical three-dimensional layout of the connection facilities in the hub area in the subsequent examples;Finally,through the current status of the hub layout and the new and reconstructed expansion plan,conduct research on existing problems in the construction,and analyze the relationship between rail transit construction and railway station reconstruction,and study the urban rail transit hub.In combination with the problems and countermeasures for the construction of a comprehensive transportation hub project at a railway passenger station,a combination of setting up a comprehensive traffic integration project construction model and proposing a feasible overall construction plan will be made to make the urban rail transportation and the railway passenger station form an organic whole and the entire integrated hub The project is more intensive and three-dimensional.The research goal of the dissertation is to explore the construction of the Lanzhou Rail Transit Railway Station Integrated Hub Project as a large-scale urban traffic complex integrating urban rail transit,railway passenger transport and other urban traffic transfer functions.It is hoped that the analysis and relevant conclusions of this paper can provide some help for the implementation of the future rail transit Lanzhou Railway Station Project.
