Abstract: This study developed an approach for measuring elderly passengers' abilities and to explore their difficulties in accomplishing the actions and motions required to patronize the bus service. A conceptual framework about the required actions and motions in bus-taking was established and a questionnaire with 18 items was designed to test their ability to use buses. A face-to-face survey was conducted to collect self-rated information from 304 elderly bus passengers in Taipei. The Rasch model was applied to estimate the difficulty of each item and the ability of each person to use a bus. Results showed the relatively difficult items primarily involved keeping balance on the moving bus, reading the posted information at the station, and recognizing the buses approaching the stations; the levels of physical ability were negatively associated with the respondent's age. Suggestions are made based on improving the facilities or services to help the elderly passengers achieve the necessary actions or motions for using the bus service.
