Statewide Travel Forecasting Models

This synthesis describes statewide travel forecasting models designed to address planning needs and provide forecasts for statewide transportation, including passenger vehicle and freight movement. It discusses the types and purposes of models being used, integration of state and urban models, data requirements, computer needs, resources (including time, funding, training, and staff), limitations, and overall benefits. Five case studies are included, two that focus on passenger components, two on freight components, and one on both passenger and freight. In addition, definitions of common technical terms and an annotated bibliography of statewide and national forecasting techniques are provided. An excerpt from the Guidebook on Statewide Travel Forecasting Models concerning passenger and intercity travel forecasting is included as an appendix.
