Research On Urban Rail Transit Station Lighting Environment Design To Enhance Passenger Travel Efficiency

With the extension of urban rail transit,the number of stations gradually increases and its function tend to be complex,brings challenges to passengers travel.Lighting can shape spatial atmosphere,affect mood and task performance,create visual environment,which is related to the process of passengers’ cognition of space,movement and recognition of visual information in the station.In order to enhance passenger travel efficiency,this paper firstly collects rule of passenger travel.Then conducted field research to know the lighting status,lighting environmental parameters distribution law;The reasonable value of lighting environment variables is explored through scheme simulation.Finally,lighting design strategy is proposed to enhance passenger travel efficiency.By theory analyzed,the types of stations and the composition of places are analyzed.The theoretical basis of spatial cognition,behavior and visual organization of passengers is sorted out.The image of city including spatial cognition;The theory of wayfinding in passenger traffic;Gestalt of visual organization.Field research was carried out at 41 stations in 6 cities to understand passenger travel and lighting environment status of stations.The research results collected the characteristics of passengers,station lighting environment elements related to passengers’ visual and psychological feelings.The localized lighting areas are divided as follow,station hall can be divided into: the central area,travel area,vertical transportation area,facilities service area,the platform can be divided into: the middle area,the waiting area,through the choice of lighting source,lighting design strategy,material setting.The lighting parameters of different areas were evaluated and suggestions were proposed.Finally,the analysis of data distribution shows that the illuminance of the waiting area in the platform is larger than that of the middle area.In the station hall localized lighting,there are illumination gaps in the central area,the travel area and the facilities service area,corresponding illuminance adjustment suggestions are put forward.Combined with passenger transit rule,DIALux evo simulation was used to explore the design reference of station localized lighting.Through comparison of simulation results and task evaluation,the direction and shape of lighting source,lighting fixture installation and layout,lighting collocation and transition area processing are proposed for station hall and platform lighting environment.In addition,the guidance and key lighting of the station hall were reformed to the improvement effect of guidance and accent lighting on passenger space cognition is verified.According to research summary and simulation,based on five elements of "city image"-landmarks,area,node and area,proposed lighting design strategy of six dimensions,including site clearly positioning,distinguish the lighting time,partition design,outstanding node characteristics,strengthening road guide,deepen the boundary characteristics specific.On the basic behavior of passengers in the station--travel,this paper discusses the design strategy of lighting environment in rail transit station to enhance passenger travel efficiency.Create convenient travel environment for passengers,and provide reference for the study of light environment of public space.
