Abstract
This paper is concerned with the activity pattern for aged drivers. At present, the population of the aged is over 20% in our country. Along with it, the percentage of driver license holder is rapidly increased, and number of traffic accidents by aged person is increased too. Therefore, these are becoming a serious social problem. As one of the remedies, the construction of support systems for aged drivers is needed. Therefore, using person trip survey data, it is important to analyze activity time for not only aged driver but also the other generation. From the results, it is possible that the aged driver's activities at the near future are estimated.
