The Freight Analysis Framework (FAF) estimates commodity flows and related freight transportation activity over the national highway network, waterways, and rail system among states, sub-state regions, and major international gateways. The end product of the FAF provides not only trade and economic pattern data but also congestion/capacity data associated with all the transportation networks carrying out all the trade activities. To make the FAF a more effective tool for measuring and analyzing the changing world of freight transportation, FHWA is depending heavily on the 2002 Commodity Flow Survey (CFS) to update the FAF and assure that the next generation of FAF methods and products is both transparent and reproducible. The CFS will be the cornerstone of the FAF Origin and Destination Database of commodity flows among the 106 to 114 CFS regions plus major international gateways, benchmarked every 5 years and updated annually with provisional estimates. The 2002 benchmark Origin and Destination Database will include forecasts every 5 years from 2010 to 2035; the 2007 benchmark Origin and Destination Database will include forecasts through 2040.
