Modeling Household Interaction in Daily In-Home and Out-of-Home Maintenance Activity Preparation

In order to realistically model activity-travel behavior, the interdependence of activity travel patterns of household members needs to be explicitly accommodated. This study examines household interactions impacting weekday in-home and out-of-home maintenance activity generation in active, nuclear-family households. Data from the 2000 San Francisco Bay Area Travel Survey was used in the model estimations. The in-home maintenance activity generation is modeled by examining the duration invested by the male and female household heads in chores using a seemingly unrelated regression modeling system. The out-of-home maintenance activity generation is modeled in terms of the decision of the household to undertake shopping, allocation of the task to one or both household heads, and the duration of shopping for the person(s) allocated the responsibility. A joint mixed-logit hazard-duration model structure is developed and applied to the modeling of out-of-home maintenance activity generation. The results indicate that the daily time investment of the husband and wife in household chores is significantly impacted by individual/household characteristics and the daily mandatory activity participation characteristics of the household heads. Traditional gender roles continue to exist, with non-working women more likely to share a large burden of the household maintenance tasks. The model for out-of-home maintenance activity generation indicates that joint activity participation in the case of shopping also is motivated by resource (automobile availability) constraints.
