Activity-based Travel Behavior Analysis Using the Disaggregate Logit Model

The research applies an activity-based disaggregate nested logit model system of individual's travel behavior. A tour is defined as a number of trips traveling from home to one or more activity locations and to home back again. The analysis focuses on home-based maintenance and discretionary tour for workers and non-workers separately, including husband and wife and single householder with family. A person trip survey data for the Nagaoka Metropolitan Area conducted in 1999 was used to demonstrate the system. Activity pattern consists of important decisions for the day's activities and travel, whether to travel or stay at home. Travel models include choice of activity pattern, time of day and mode, and higher levels assume to be influenced by lower levels. For the workers model, its estimation reveals that working conditions influence mode choice, time of day choice and activity pattern choice in performing maintenance and discretionary activity, but without any feedback interaction. For the non-workers model, activity pattern, time of day and mode choice were estimated as a sequential nested logit model system. Particularly decision of activity pattern is influenced considerably by time of day choice.
