Assessment of a Route Guidance for Mobility-handicapped Passengers in Railway Stations Based on User Satisfaction Survey

As of 2018, the mobility handicapped population accounts for about 29% of the total population, which is expected to increase continuously. Various studies are actively underway to ensure the increasing convenience of the mobility handicapped. In order to introduce these new policies and technologies, satisfaction evaluation should be performed for the system under development. Therefore, in this study, a user satisfaction survey was conducted for the route guidance system for the mobility handicapped in railway stations. This study consists of three stages: sample and questionnaire design, field demonstration and satisfaction survey, data processing and analysis. A questionnaire survey was conducted in Busan City Hall station for 33 visually impaired people, and satisfaction with the system and user requirements were investigated. As a result of the survey, the satisfaction level of the railway before using the system was 4.13 points and 7.34 points after use, and as a result of investigation of the intention to use the system, about 84.8% of respondents said that they intend to use the route guidance system if it is introduced. The results of user satisfaction surveys conducted in this study can be used as a basis for more stable system development.
