About Travel Monitoring

Data and information on traffic volume, vehicle classification, and truck weight are basic to many highway and transportation functions. The 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 highway legislation. 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 and include data products periodically updated, software to process the data, paper reports provided as information, related databases, and information on related issues. Links to relevant organizations are also included to make your search easier.
