Data and information on traffic volume, vehicle classification, and truck weight are basic to many highway and transportation functions. The Federal Highway Administration's (FHWA's), Office of Highway Policy Information has traditionally maintained national programs to track traffic trends, vehicle distributions, and weight to meet data needs specified in federal highway legislations. Activities include development of guidelines, regulations, direct data collection (from State DOT sources), data processing, research, analysis, and professional conferences. The products of these activities are listed in the publications in the next column.

The publications and reports on travel monitoring include data periodically updated, software to process the data, paper reports, related databases, and information related issues. Links to relevant organizations are also included to make your search easier.
