Analysis And Modeling Of Characteristics Of Passengers Walking In Urban Rail Transit

The rapid development of urban rail transit is one of the symbols for Chinese society urbanization and which accelerates the pace of urban city.Urban rail transit in many cities at home and abroad is proved to solve the problem of urban traffic congestion remedy in the development of the city,greatly improved the city's economic structure,and which also promotes the prosperity and development of related industries.The designing and evaluating of outbound port and stop port,check-in office,transfer hub access,stairs and related facilities that must combine with the walking characteristic of passenger in the urban rail transit;safe,fast,comfortable,convenient and reasonable urban rail transit facilities confi-guration should conform to the various kinds walking characteristic with passenger's trip.With the accelerating pace of urban life,the problem of improving the movement of passengers in the station efficiency,reducing the time delay in outbound port and stop-port,check-in office,transfer hub access,stairs,has drawn increasing attention to relevant departments and researchers.The dissertation analyzes the composition of urban rail transit passengers from three aspects:the passengers'age,gender,luggage.Getting the ratio between the passengers and com-position characteristics.On this basis,the urban rail transit passengers'walking characteristics are defined and parameters are described,which leads to the focus on the study the pass-engers'step frequency,stride,walking speed and personal space.In the channel of the Urban Rail Transmit,the relationship upon the step frequency,stride length,walking speed and the personal space is obtained to establish the each model about step frequency-stride length,step frequency-walking speed,stride length-walking speed,by col-lecting and analyzing the data of step frequency,stride length,walking speed and the personal space of passengers at the level,beginning and end of the slope.On the stairs of the Urban rail transit,the stride length and walking speed are defined on the stairs at first,which are divided into horizontal and vertical directions,then the cha-racteristics of the passengers are analyzd in the horizontal direction and vertical direction of the step frequency,stride length, walking speed respectively,the model of step frequency-stride length,step frequency-walking speed,stride length-walking speed are established on the stairs,and the analysis of the factors about stairs and escalators are given which to choice.Finally,the transfer mode of transferring hub station of urban rail transit are analyzed,and the walking characteristics of passengers in the commuter station,establishes the model of walking characteristics of different interchange position,and fits the model parameters;it con-firms the model on the Shuniu station-Dongan station of Shanghai urban rail transit line No.4 and7,and the result shows that the model has strong adaptability. The research shows that walking characteristics of the passengers in the urban rail trans-mit are different obviously with these in the squares,streets,parks and so on.Researching the walking characteristics of the passengers in the urban rail transmit,which is very important theoretical value and significance to plan and design of urban rail transit.
