MODELING TRAVELERS POSTWORK ACTIVITY INVOLVEMENT - TOWARD A NEW METHODOLOGY

The objective of this study is to develop a methodology capable of mod eling travelers' postwork activity patterns and thus tracing the movem ents of travelers through space and time. After reviewing the state of the art in activity participation and scheduling, a modeling system c onsisting of a set of discrete/continuous models and duration-based mo dels is specified and estimated. The discrete/continuous models are us ed to predict the travelers activity-type preference (discrete), the t ravel time to the activity and back home (continuous), and activity du ration (continuous). Duration models are used to model the travelers h ome-stay duration capturing the factors that motivate travelers to ter minate their home-stay and undertake additional out-of-home activities .
