The purpose of this study is to determine the relationship between car travel cost and mode choice, by the income level and travel purpose. This study articulates the economically accessible boundaries of total travel networks and estimates the gasoline prices in each boundaries. Next, these price data and household travel diary data are analyze through multinomial logit model. Analysis result indicates that as the gasoline price of travel boundary increases, probability of private car use tends to decrease. This implicates that high oil price policy is good for reducing transportation consumption and cost. However, results of stratified sample model identified that impacts of gasoline price are different by the income group and travel purpose: marginal effects of gasoline price are more elastic in the low income group and shopping trip than high income group and commuting trip. This result shows that high oil price policy leads low income people in dilemma: renunciation of private car use or payment of large amount of travel cost. Therefore, the government should consider a subsidy policy for low income group on commute trip, if recent high oil price situation continues. |
