抄録

In Japan, the travel time especially the commuting time in the metropolitan areas, for example, the Tokyo metropolitan area, is so long that it becomes a social problem the government faces to. In order to make an appropriate policy, it is neccessary to understand the current situation. Surely, the analysis may be made from many different viewpoints. Authors are going to emphasize with the knowledge of the travel activity analysis.
This study aims to analyze the difference of one day's travel time among the prefectures in Japan, and then the relation between transportation and activities. The study is based on the ideas of the time budget of travel activity analysis.
The data used in the study have been collected by NHK every 5 years. Therefore the time serial analysis can be carried out. The time serial data are used to investigate the change of travel time (one day's travel time). Further, the cross-section data are used to make the regression analysis between the one day's travel time and the other social, economic and transportation factors in the unit of prefecture. Moreover, the factor-analysis are made for understanding the characteristics of each prefecture.
