This study investigates the effects of gender, current use of cars/motorcycles, and convenience of public transit on travel characteristics for the elderly by using a questionnaire survey. A total of 1273 valid questionnaires were collected. Survey analysis reveals that the mobility of many elderly people is limited to using a motor vehicle for outdoor activities, especially for the elderly living in areas where public transportation services are not convenient. Demand Responsive Transportation Service (DRTS) can provide the elderly with convenient transportation services upon request. This study examines the willingness of elderly people to take a DRTS bus for a medical trip. The analysis results of the questionnaires survey study reveal that 610 (48%) subjects expressed willingness to take a DRTS bus. The factors contributing to the willingness of the elderly to use a DRTS bus for their medical trips include: age, education level, most frequently used transportation mode for going to a hospital or clinic, distance to the closest hospital or clinic, and walking distance to the nearest bus stop from home. This survey also asked the subjects what kinds of trip purposes they desired to take a DRTS for. They expressed that they would like to take the DRTS bus for their medical services, recreational, shopping, and religious activities.
