Abstract:

Activity-based models (ABM) are very sophisticated and consist of a number of interrelated, discrete choice modeling components. That is, the upstream model components (long-term choice models) provide inputs to the person-level models (daily activity, intra-household interactions) which, in turn, provide inputs to tour-level models (destination, mode, time of day) and, finally, trip-level models. Due to the number of model components, the complexity of the various models, and the amount of information passed between models, there is a high chance of error propagation if all of the components are not properly calibrated and validated. A rigorous calibration process is necessary for various levels – geographic (regional, sub-regional, county, or district), market segments (income, trip purpose), and household structures and person-types (gender, full time worker, etc). This paper discusses the need for a detailed validation plan and lays out priorities for different tests to be performed. This paper focuses on a comprehensive methodology that was laid out for the Houston- Galveston Area Council (H-GAC) ABM development effort. This paper also presents example calibration results from the H-GAC ABM validation effort for several ABM components.
