Research On Pedestrian Flow Guidance In Subway Station Based On Visual Perception-oriented Design

Rail transit,which is mainly based on subway travel,is the key to solving travel problems in future cities under the pressure of rapid population density growth.However,in the closed subway space,the dense flow of people and the unfamiliar environment often have a negative impact on the passengers’ judgment and reaction ability,thus reducing the efficiency of Wayfinding.Guidance signage in the subway station plays an important role in the process of passengers’ Wayfinding,and well-designed guidance signage can ensure that passengers can quickly reach their destination without anxiety and stress.At present,most of the domestic research on the design of guiding signage in the subway station lack systematicness and crosscutting.In addition,there is no effective method for pre-testing the effectiveness of the scheme.Therefore,based on subjective visual perception,this research builds a theoretical model for the design of guide signage in subway stations.Then Virtual Reality Technology(VR)is used to verify the effectiveness of the theoretical model.At last,a systematic evaluation framework is proposed to test the applicability of flow guidance design in subway stations.Based on the above background,the main work of this research is as follows:(1)Construction of theoretical model based on visual perception theory.Based on the analysis of Gestalt psychology,cognitive psychology,and environmental psychology of visual perception theory,combined with the behavioral characteristics of passengers in the subway stations,and integrated into the evaluation of design Affordance,a theoretical model of oriented design based on visual perception is proposed.(2)Application of the theoretical model based on case study.Taking Nanjing Daxinggong subway station as an experimental case,focusing on one of the pedestrian flow area,applying the theoretical model to analyze the effectiveness of the existing guide signage design,and proposing an optimization plan for pedestrian flow guidance.(3)Verification of the theoretical model based on Virtual Reality(VR)experiment.(4)Evaluation framework based on the theoretical model.Guided by the theoretical model,a comprehensive evaluation framework is established to test the applicability and effectiveness of the guidance signage scheme from three different dimensions(overall environmental perception,objective quantification of data,and subjective system evaluation).In addition,combining theory and practice,put forward specific suggestions for the guidance of pedestrian flow in subway stations.Through the arrangement,application and verification of the theoretical theory,the conclusions of this study are as follows:(1)the Theoretical Model of Guidance Signage Design based on Visual Perception proposed in this paper has significant validity and applicability in the flow guidance of subway stations.(2)Virtual Reality Technology(VR)can be used as an effective method of scheme evaluation and pre-testing.(3)The guidance signage designed based on the theoretical model of visual perception can significantly affect the wayfinding decisions of passengers,balance the utilization of transfer facilities,and reduce the occurrence of congestion.(4)The guidance signage following the guideline of visual perception design model can effectively reduce the cognitive barriers caused by environmental pressure in subway stations to passengers in the process of wayfinding.(5)The guidance signage in line with visual perception design principles can improve the way-finding efficiency of passengers,and their guiding role can be better played in a large passenger flow environment.
