The Effect of Sociodemographic Characteristics on Individual Daily Travel Behaviour
This study examiens the hypothesis that daily travel-activity behaviour is influenced by the household role, life cycle and other attributes of individuals and households using conventional origin-destination data sets. Daily travel-activity behaviour is described by ten categorical factors including trip rate, number of trip chain, number of sojourn, daily travel time, trip patterns and five different activity hours. The explanatory variables used in this study are life cycle, age, role, household size and car ownership.
A specific representation in time and space of travel-activity relationship and a statistical analysis based on the log-linear model are employed to test the hypothetical relationship. The former qualitative analysis demonstrates that life cycle is a key determinant in deciding wife's travel behaviour, while husband and children are not influenced by life cycle in their daily travel behaviour. The latter statistical analysis confirms above empirical evidence and derives a further fact that daily travel-activity behaviour of wife in the household is significantly influenced by her role and age as well. This result indicates that interdependences of all household members in their daily travel-activity behaviour reported from European and American countries cannot be seen in Japan.
