A STUDY ON ACCESSIBILITY AND GOING-OUT BEHAVIOR OF AGED PEOPLE CONSIDERING DAILY ACTIVITY PATTERN

This paper examines the relationships between accessibility and going-out behavior of aged people in a framework of space-time constraints. We collected activity diary data together with data of desired patterns of time use and satisfaction level in daily life. The analysis shows that some aged people desire to do more in-home discretionary activities and to go out more frequently to do out-of-home discretionary activities. Non-working aged people who satisfied more with their daily life go out more often to do discretionary activities and the amount of time spent on out-of-home activities is larger. By developing a choice model, it is revealed that accessibility to activity opportunities available in the space-time prism effect the choice between in-home and out-of-home discretionary activity.
