Research On Passenger Flow Transfer Organization In Dalian North Railway Station Comprehensive Transportation Hub

With the improvement of China's economic development level,the demand for residents'external traffic has increased.More and more cities have begun to build large-scale integrated transportation hubs,and there are a variety of transportation modes around them,accompanied by a large number of passenger flow,transfer facilities and commercial buildings.The comprehensive transportation hub based on railways is an important transportation place connecting the interior and exterior of the city.The large-scale railway hubs established in recent years,such as Harbin West Railway Station,Shenyang North Railway Station and Fuxin South Railway Station,all combine various transportation modes.Improve the transfer efficiency of passengers in and out of the station and nearby residents.It is of great practical significance to study the passenger flow of large-scale integrated transportation hubs and the organizational optimization of the transfer streamlines in the hubs by scientific methods.It is of great practical significance to improve passengers' travel comfort,overall operational efficiency and service quality of the hub.It first systematically analyzes the development history and scale research of large-scale comprehensive transportation hubs at home and abroad in this paper.According to the actual situation of China's comprehensive transportation hub,it mainly predicts the passenger flow forecasting method and the flow of passengers between the various modes of transportation.In-depth study of the method of quantity allocation prediction and streamline organization optimization.Based on the analysis of the status quo hubs at home and abroad,the comprehensive transportation hub facilities and streamline theory are briefly described,and the composition of the hub transfer system and the transfer streamlines and facilities service capabilities are analyzed.Secondly,it puts forward the idea of changing the passenger flow forecast by the comprehensive transportation hub based on railway,analyzes the characteristics and composition of the passenger flow,and introduces the method of predicting passenger flow.Furthermore,the method of predicting passenger flow is proposed.The grey forecasting model is used to predict the total passenger flow in the future.On this basis,the maximum entropy model is used to predict the passenger flow between different modes of transportation.After that,through the questionnaire survey on the main influencing factors of passengers'choice of various modes of transportation,the analytic hierarchy process is used to calculate the section impedance of each mode of transportation,and the traffic flow between various modes of transportation is predicted according to the theory of traffic flow distribution.Based on the establishment of the pedestrian flow impedance function,the TransCAD software is used to distribute the passenger flow,which can intuitively reflect the passenger flow in the internal streamline of the hub.Finally,the research on the transfer line organization of the integrated hub is carried out.Through the generation of the streamline,the layout of the transfer stream inside the comprehensive transportation hub of Dalian North Station is analyzed and the conflicts and bottlenecks appearing in the internal organization streamline of the hub are proposed.In this regard,this paper proposes an organizational optimization model,which uses the generalized cost model to calculate the generalized cost of each node and the entire hub system.Then,according to the traffic flow line allocation map and the generalized cost value,the streamline organization is carried out from the two aspects of the facility and the travel path.Optimize and propose the corresponding organization plan,through comparative analysis,explain the effectiveness of the optimization plan,and provide theoretical basis and decision-making basis for the actual operation management of the completed Dalian North Railway Station comprehensive transportation hub.
