Fundamental Study of Intra-household Activity Time Allocation Model for Elderly Couples with Time and Budget Constraints

We conducted a fundamental study for modeling intra-household activity time allocation for elderly couples, with the prospect that it might contribute to analyzing travel behavior of increasing “active seniors”. We formulated a household activity time allocation model that considers both time and budget constraints. The data drawn from the nationwide survey on time use and leisure activities is used for the identification of the model. Finally, the sensitivity analysis of utility level and time use patterns are conducted.
