In 1993, the U.S. Department of Transportation and the Environmental Protection Agency established the Travel Model Improvement Program (TMIP) to address the shortcomings of travel-forecasting procedures that were developed 30 years ago. The program pursues six tracks of activity: outreach, near-term improvements, long-term improvements, data needs, land use, and freight. This feature presents descriptions of each TMIP track and provides examples of projects funded by TMIP, which are at various stages of completion. During the early phase of TMIP, the focus was on designing and setting a general direction. Approximately 4 years ago, the focus began to shift toward product development and testing. The program, which has involved the user community and is structured to meet both near-term and long-term needs, will continue to be oriented toward meeting the needs of state governments and metropolitan planning organizations. In the future, its primary emphasis will be on product delivery and implementation. A list of TMIP contacts is provided for up-to-date information on specific projects.
