TRAVEL MODEL IMPROVEMENTS--FROM CURRENT PRACTICE TO STATE OF THE ART
The federal government's Travel Model Improvement Program (TMIP) seeks to replace the traditional four-step model with a new generation of activity-based/microsimulation models. The new models would be capable of capturing the complexities of travel behavior, traffic operations, and vehicle emissions, resulting in better forecasts. Receptivity to change, however, is a major concern and the subject of a recent survey of model users in Florida. Users were versed in the conventional four-step modeling structure and were asked open- and closed-ended questions about their modeling needs. Overall, the survey revealed how receptive users are to fine tuning versus model restructuring. This article presents a hierarchy of model improvements, a summary of the survey results based on the hierarchy, and a discussion on the implications for model improvement efforts by Florida and other states.
