Abstract
In order to explore transportation-related actions that can be taken in response to falling birthrates, the present study investigates the characteristic travel behavior of women who have an infant or toddler. Data from the 4th Person Trip Survey in the Northern Kyushu Region was used for analysis. The female subjects were classified into three groups: 1) women with an infant, 2) women with a toddler, and 3) women with an elementary school age child, an older child, or no children. The three groups were compared to determine what percentage of the subjects made at least one trip per day, the average number of trips per person per day, the typical mode of transportation, the distance of the trips, and the duration of the trips. The results revealed statistically significant differences among the three groups. Specifically, women with an infant or toddler were less likely to use public transportation, and exhibited a higher dependency on private vehicle. Furthermore, with regard to how the subjects selected the mode of transportation, a parameter estimation was obtained by using a disaggregate logit model. This also indicated that women with an infant or toddler show a stronger dependence on their private vehicle than those without an infant or toddler.
