Abstract

It is expected that the population will decrease, on the one hand our society be composed largely of an elderly people and less children in one family. Such society will lead to some change in constitution of household, increasing single households as an example, and finally will effect to the trip behavior. This study aims to reveals those themes based upon the results of Tokyo Metropolitan Person Trip Survey: the differences between the trip behavior because of its own circumstances (or household constitution), the change of the behavior with the times. In addition, we tried to calculate the Tokyo's vehicle traffic volume in 2025, then it reveals that the prospect of future transportation demands will be greatly varied according to considering to the change in households attribute or not.
