The increase realities of various action groups of the automobile dependence type that became the origin of a transportation negative environmental impact increase will be quantitatively clarified in 2005 in this research in 1987. Moreover, a large-scale attitude survey was originally executed to the driver, and what driving motive those who belonged the action group about the car dependence type had was clarified. It was quantified that the composition ratio of the action group that highly depended on the car had risen as a result of the analysis in recent years. On the other hand, it was newly clarified that the action group that depended on the car and the layer where the convenience improvement of public traffic was expected existed in the inside, too when seeing from the driving motive.
