Research On Guide Sign Layout Of Urban Rail Transit Station Based On Passenger Behavior Psychology

With the increasing of urban rail transit stations scale,the internal space layout and streamline design are becoming increasingly complex,but the internal activity space of the station is limited and the sense of direction of passengers is poor.Therefore,the guide sign plays a prominent role in guiding and evacuation in urban rail transit stations.Its reasonable layout can not only meet the routing needs of passengers,improve the distribution efficiency of passengers,but also improve the service level of the station.The layout of guide signs in engineering practice is based on relevant specifications and standards,which is lack of flexibility and applicability.Insufficient consideration of the spatial layout of the station and the psychological behavior of passengers affected by it leaded to poor integration between the layout of guide signs and different spaces of the station,which reduces the efficiency of passenger routing,even leads to instantaneous congestion in the station.Therefore,considering passenger behavior psychology,the station space layout and existing streamline design are more reasonable for the layout of guide signs.The paper mainly does the following work:(1)Analyzed the behavior psychological factors of passengers that affect the layout of guide signs and reveals that passengers’ behavior is the specific expression of internal psychology.It is proposed that passenger behavior psychology is affected not only by their own attributes,but also by the external environment,such as station space layout,facilities and equipment layout and passenger streamline design.Define the information acquisition intensity and attraction of guide signs,analyze the interaction process between passengers and guide signs,and find that passengers have different guide needs in different spaces of urban rail transit stations.(2)Analyzed the interactive relationship between passengers and space environment and put forward that passengers’ perception of space affected their behavior psychology.Reasonable space layout could effectively induce passengers’ behavior.Divided the internal space of the station based on the passenger flow line and the location of facilities and equipment,then calculated the efficiency,accessibility,understandability and coordination of different spaces of the station.It is found that the efficiency and accessibility of different spaces in the station were different,and the attraction to passengers was different.The layout of guide signs needed to be coordinated with the spatial layout of the station.Based on the analysis of the spatial view of the station,it was proposed that the guidance signs should be arranged along the passenger flow line or near the facilities and equipment on the station hall as far as possible;Guide signs shall be symmetrically arranged on both sides of the platform as far as possible to reduce the impact of obstacles such as bearing columns on passenger routing.(3)Taking Jintai Lu station as an example,the optimal height range of signage layout was determined through passenger perspective analysis.According to the spatial layout and streamline of Jintai Lu station,the alternative points of guide signs were determined,and a horizontal layout model of guide signs was established,which took the maximum utility of guide sign layout as the objective function and at least one guide information guide at each destination as the constraint condition.In addition,considering the psychological acceptance of passengers,a horizontal layout model of guide signs based on the dual objective constraints of spatial guidance level and passengers’ psychological experience was established.The solutions of the two models basically meet the needs of passenger routing,and the appropriate solution results can be selected according to the actual needs.(4)The layout simulation model of guide signs in Jintai Lu station was constructed based on Anylogic,and the influence of information acquisition intensity and attraction of guide signs on passengers was added.Aiming at the problems existing in the layout of guide signs of Jintai Lu station,this paper put forward optimization measures.Through the simulation data before and after optimization,it is found that after the optimization of the guide sign layout of Jintai Lu station,the average density of passengers in the fuzzy area of guide sign identification was reduced by 36.6%,the average travel speed was increased by 22.85%,and the average consumption time was reduced by 35.89%.
