Abstract: For evaluating rationality of transfer facilities in passenger transport hubs, a study focusing on level of walk service is carried out.At first, walk time is selected as an index to evaluate the level of walk service, which is divided into 5 levels.Then based on continuous category evaluation theory, a classification method to evaluate level of walk service in passenger hubs is developed.According to the survey data of "experience-response" of passengers, the criteria ranges of 5 levels of walk are given.The results indicate that passengers generally perceive 10 min walking is acceptable when transfer in hubs;however, 18 min or more will beyond their tolerance.The results of this study also demonstrate that the continuous category evaluation method is similar with the psychological evaluation process of passengers on the level of walk service.It is suitable for determination of thresholds for each level of walk service.
