Research On Passenger Flow Conversion Capability Of Urban Multi-mode Transportation Network Hub

In recent years,with the advancement of urbanization and the continuous expansion of urban scale,the total traffic demand and travel distance have been increasing,and one trip often requires one or more modes of transportation to complete.In order to solve this problem,large amounts of funds have been invested throughout the country to build urban transportation infrastructure.Multi-modal transportation networks such as urban rail network,public transportation network and slow-moving network have developed rapidly.But on the other hand,urban traffic congestion has become more serious.Therefore,people gradually realize that it is impossible to solve the increasingly serious traffic problems by a single road network,and it is necessary to strengthen the coordination of various modes of transportation.The transportation hub i5 a key node for passengers to realize multiple modes of transportation or different lines of the same kind of traffic.In view of the problems such as insufficient transfer capacity of rail transit hubs in many cities,mismatched transportation capacity,and long transfer time,The paper studies the passenger flow conversion capability of urban multi-modal transportation hubs,and it is of great significance to improve passengers' transfer efficiency,give play to the combined advantages of difierent modes of transportation,give full play to the potential of conversion,and promote the overall efficiency of comprehensive transportation resources.The thesis starts from the connotation and classification of urban multi-modal transportation hub,and discusses the transfer mode inside the hub and outside the hub.From the perspective of the hub and the hub,it has generalized the transformation feature of urban multi-modal transportation hub passenger flow from the time characteristics,the spatial characteristics,the multi-directional multi-path,the high concentration,the time superposition,the difference of connection traffic selection,and it analyze the influencing factors of passenger flow eonversion.By analyzing the structure and function of various transfer facilities in the hub and the traffic characteristics of passengers through transfer facilities,it is found that the capacity of the hub is mainly affected by the scale and layout of transfer facilities.And combining the transfer passengers to rule,available shuttle transport capacity and traffic conversion feature,and by using queuing theory and operational research related basic theory,the paper established the calculation model city of multimodal transport hub transformation ability.Then,for the hubs with insufficient passenger flow conversion capability,the adjustment and improvement measures are proposed from the aspects of determining the scale of transfer facilities in the hub,determining the waiting facilities for the external connection of the hub,determining the number of connected vehicles,and matching the traffic evacuation and transportation capacity.Finally,through the field investigation,the Harbin West Railway Station and the museum subway hub are taken as examples to illustrate the application and solution process of the model,and corresponding improvement measures are proposed for each of the two hubs.The example analysis shows that the research on passenger flow conversion capability of urban multi-modal transportation hubs plays an important role in improving the efficient connection and coordination of various transportation networks,better service diversification travel demand and complex traffic flow.
