Abstract
Recently, the residents who live in the countryside seldom use the public transportation that they could use. The purpose of this paper is to find the factor to change their behavior from car use to public transportation use. Focusing on the consciousness of importance of public transportation, we examine the effect of this consciousness by quantitative method. The findings are as follows: (1) while the public transportation users are old-age women, the car users are young or middle-age office workers. (2) The car users have the tendency to overestimate the travel-time by public transportation and to underestimate the risk of fatalities from traffic accidents. (3) The consciousness of importance of public transportation can control the overestimation and underestimation of car users.
