Passenger Flow Simulation And Spatial Optimization Design Of Metro Transfer Station Based On Agent

Urban rail transit(URT)is an energy-saving,efficient and environmentally friendly mode of transport.Therefore,it has developed rapidly in large and medium-sized cities in China and become the mainstream direction and core of the development of public transport in large and medium-sized cities.Metro transfer space design is an important factor affecting station efficiency,and inefficient transfer space hinders the rapid development of rail transit.Metro transfer station is an important part of modern rail transit system.Its architectural design function is complex,involving a wide range of areas and strong professionalism.In the design of metro transfer station,at present,the macro-environment such as urban development is mostly used,while the micro-passenger traffic behavior is seldom studied.And the complexity of passenger traffic behavior is the focus and difficulty of Metro design.Through the understanding of passenger traffic behavior simulation research in rail transit buildings at home and abroad,we can see that the passenger simulation research in traffic buildings has developed to a certain extent,and passenger data suitable for local conditions have been accumulated at home and abroad,and the corresponding theoretical knowledge has been summarized.In the study of the design of the station traffic space,the research on the layout of the traffic space related to passenger popularity is still in the initial stage of exploration.However,the application of the simulation study of passenger traffic behavior to guide the design of the public traffic space of the subway transfer station,passenger flow organization and management are relatively few.This paper simulates the use characteristics of traffic space in rail transit hub station with the data of passengers'use of space and facilities,provides the construction method of spatial data model of metro public transport,provides the evaluation methods and optimization theory basis of passengers' use of space in station,pedestrian traffic safety,efficiency and comfort,and reduces the use of public transport space through optimization of public transport space.Less passenger behavior disorders due to congestion and unreasonable use of space.The coupling relationship between public transport space and passenger behavior at metro transfer station is complex,and it is difficult to study qualitatively.It is necessary to provide quantitative support for the design of public transport space through passenger popularity simulation.The public transport space of metro transfer station is the basic carrier of passenger traffic behavior,the important place of urban public life,and the design core of metro transfer station.Therefore,we urgently need to have a fine and accurate grasp of it.Based on the study of passenger traffic behavior,starting from the coupling relationship between metro public transport space and passenger popularity,this paper implements passenger transfer experience and traffic efficiency,which is reflected in the optimization design of public transport space.Passenger flow simulation is an important application of simulation research in the design of metro public transport space.It uses computer model to visually reproduce the traffic behavior of complex passenger flow in metro transfer station,and quantitatively describes the behavior of passenger groups by means of data tables.In this study,a detailed field survey of Beijing Metro West Bureau Station was carried out.Traffic behavior and related data of 714 passengers during the early rush hour were recorded by tracking method,and multi-dimensional simulation analysis of the station was carried out.The results of the analysis were compared with the field survey results,and the relevant simulation parameters were determined.Finally,the research results are applied to the optimization design of traffic space of Shiyuan Station of Beijing Metro,and combined with humanization and ecology methods.By discussing the guiding role of the simulation of passenger flow in the design of metro transfer station traffic space,it will be helpful and useful for the optimization design of metro transfer station traffic space in the future.
