RECENT ADVANCES IN ACTIVITY-BASED TRAVEL DEMAND MODELING

This paper presents an overview of recent and on-going advances in activity-based travel demand modeling, organized in terms of the methodologies employed (including computational process models, structural equation model systems, and hazard-based duration models) and the phenomena being modeled (including in-home and out-of-home activity participation, interpersonal dependencies, and daily activity-travel patterns). The paper sets the overview of the recent and on-going advances in activity-based travel modeling in the context of the long and rich history of activity-based travel analysis, which was first proposed about 20 years ago as an alternative to the trip-based modeling framework and the discrete choice, utility-maximizing models that were being incorporated into the trip-based travel demand modeling framework at that time. This paper finds that substantial progress has been made recently, and continues to be made, in advancing from activity-based travel analysis (with an emphasis on descriptive analysis and understanding), to activity-based travel forecasting models that can be used effectively for addressing contemporary policy and planning issues. The considerable recent effort and progress in activity-based travel modeling is attributed to technical, institutional and data availability factors.
