Abstract
This study aims at developing a quantification method of user's preference related to railway station based on Item Response Theory. Based on a questionnaire survey conducted at a total number of 23 railways, dissatisfaction level and preference level for utility improvements are measured by considering human latent traits. In the analysis, user's preference was decomposed into the element depending on latent traits and independent one. Also, it was clarified that a) latent dissatisfaction level and preference level differ depending on user's attributes and structures of stations and b) these latent traits provide a significant influence on revealed preference for an improvement of information service and comfort facilities.
