| Research Abstract |
Vehicle ownership and use can.be changed by several approaches including the structural strategies, the psychological strategies, and the providing new alternatives.
On the structural strategies, we examined the effects of the periodical vehicle inspection program in Japan and France and the grant for scrappage of old vehicles in France on household vehicle transaction. The results suggest the one year extension of the inspection period raises the holding duration by an average of about three months in Japan. The results also indicate that the expected vehicle holding duration becomes 1.3 years longer under the inspection program in France; and that the average holding duration becomes shorter by 3.3 years, when the grant for scrappage is available.
On the psychological strategies, we implemented, a field experiment to provide information about risks and costs of automobile use and psychological depression due to road traffic congestion, to university students around 18 years old not holding a driving license. The results indicated that due to the information provision, belief about negative aspects of automobile use were strengthen, intentions or motivations to use, automobile decreased, and the driving license holding behaviors were suppressed.
On the new alternatives, we investigated an experimental carsharing project in Kyoto. We examined the effective fleet management using a simulation model of system operation, and the strategies on membership recruiting and locating the parking spaces. The results suggest that the optimal number of vehicles is about 70% of,the total number of parking stalls, and that increasing the number of the parking stalls is more effective by 20% than increasing the number of stations. The results also suggest that business trips and female members have a higher probability, of changing trip timing, thus contributing demand dispersion, and that the parking spaces should 'be located close to railway stations or shopping destinations.
