Research Of Sign-oriented System Optimization And Evaluation Of Passenger Flow In Urban Rail Transit Station

Sign-oriented system of passenger flow in urban rail transit station is an important part of urban rail transit station.It is an important means to ensure the service quality of urban rail transit station.Since most of the urban rail transit stations are built underground,the interior space is complicated,and many passengers will lose their sense of direction in the underground space,they are easily lost in the station.Therefore it is an important problem to optimize and improve that sign-oriented system of passenger flow in urban rail transit station scientifically and efficiently.This paper is based on Xi 'an Xiaozhai subway station,it take into account three elements of that in sign-oriented system formation content,visual patterns and setting space.The analytic hierarchy process(AHP)is used to establish the evaluation method of sign-oriented system of passenger flow in urban rail transit station.The optimization of sign-oriented system is carried out by means of ergonomics and mathematical modeling.Firstly,this paper comprehensively analyzes sign-oriented system of passenger flow in urban rail transit station,carries out detailed analysis from four aspects of its concept,function,classification and setting form.And the influence factors of its setting are analyzed,the influence factors of station space characteristics,passenger characteristics,passenger flow line and information demand are analyzed in depth.In which that passenger characteristic is based on an analysis of passenger questionnaire survey of Xiaozhai subway station and ergonomics.Secondly,it establishes the evaluation system and evaluation method of sign-oriented system of passenger flow in urban rail transit station,in which the sign-oriented system evaluation system takes into account the influence factors of sign-oriented system setting.It is established according to the relevant requirements of three elements of that in sign-oriented system formation content,visual patterns and setting space.The evaluation method of sign-oriented system is established by analytic hierarchy process(AHP).Then,according to the optimization principle of Sign-oriented system of passenger flow in urban rail transit station the optimization method is determined in three aspects: information content,visual patterns and setting space.in which the layout of setting space is optimized to establish the point selection model,and the intlinprog function programming in the Optimization Toolbox of MATLAB is used to calculate the solution.Finally,the evaluation and optimization of Sign-oriented system of passenger flow in Xiaozhai subway station are carried out.
