Feasible Activity and Travel Time Allocations with a Discrete Model: An Exploratory Study

This paper describes an exploratory study that uses a discrete choice framework for time-use allocations. This framework is unique in that it treats time uses as discrete and independent rather than continuous and dependent. By doing this, the restriction that the consumption bundle must lie on the boundary of the budget set can be enforced. Furthermore, by using the direct translog utility function, as many details can be entered into the utility function as desired. Using responses collected from the 1996 travel survey for the San Francisco Bay Area, estimation of the model results is a good fit in terms of adjusted R-squared. The associated effects between individuals and households' sociodemographic variables and time-use behavior are all within expectations. Limitations of this model and directions for future research are discussed.
