Modeling travelers’ postwork activity involvement: Toward a new methodology

The objective of this study is to develop a methodology capable of modeling travelers’ postwork activity patterns and thus tracing the movements of travelers through space and time. After reviewing the state of the art in activity participation and scheduling, a modeling system consisting of a set of discrete/continuous models and duration-based models is specified and estimated. The discrete/continuous models are used to predict the travelers activity-type preference (discrete), the travel time to the activity and back home (continuous), and activity duration (continuous). Duration models are used to model the travelers home-stay duration capturing the factors that motivate travelers to terminate their home-stay and undertake additional out-of-home activities.
