Service Description: The Freight Analysis Framework (FAF), produced through a partnership between the Bureau of Transportation Statistics (BTS) and the Federal Highway Administration (FHWA), integrates data from a variety of sources to create a comprehensive picture of freight movement among states and major metropolitan areas by all modes of transportation. The Freight Analysis Framework (FAF) network assignment estimates commodity movements by truck over specific highways. Models are used to disaggregate interregional flows from the Origin-Destination Database into flows between localities and to assign these flows to individual highways using average payloads per truck, and truck counts on individual highway segments. Using route number and milepost, functional classification of the highway, number of lanes, and other highway characteristics for individual highway links, truck tonnage is assigned to the network segments. Models used to disaggregate flows are based on geographic distributions of economic activity rather than a detailed understanding of local conditions and the resulting network flows should not be used as a substitute for local data to support local planning and project development.
