This study empirically analyzes the factors influencing the commuting time of households with multiple commuters in Chungnam Province. In particular, we examined how the commuting time varies between commuters depending on their wage gaps. A regression equation, in which the dependent variable was the difference in commuting time, was used. The key independent variable was the wage gap for households with two commuters. Further estimations were performed on samples restricted to dual-income couples with additional variables such as the wife’s household work burden, number of preschool children, and number of caregivers for children. Based on the results of the empirical analyses using the Chungnam Social Survey, the larger the wage gap between two commuters in a household, the longer the commuting time for high-wage commuters than for low-wage commuters. This contradicts the argument that a higher opportunity cost of commuting for higher wages should reduce the commuting time. In the analysis of dual-income couples, the wife’s commuting time was relatively shorter than that of the husband’s because of the burden of housework; however, the influence of childcare was not observed. As households with multiple commuters or dual-income couples become increasingly common, and the structure of cities changes from monocentric to multicentric, deciding where to live has become more complicated. Long-time and long-distance commuting can lead to wasteful commuting, and this needs to be considered as a social cost owing to the possibility of traffic congestion beyond the loss for the individual concerned. Therefore, the government’s urban policies, including housing and transportation policies, must be improved.
