Talk Abstract: The Freight Analysis Framework (FAF) integrates data from a variety of sources to create a comprehensive national picture of freight movement among states and major metropolitan areas by all modes of transportation. It provides a national picture of current freight flows to, from, and within the United States, assigns selected flows to the transportation network, and projects freight flow patterns into the future. The FAF was designed as a policy tool for the U.S. Department of Transportation (USDOT) by the Federal Highway Administration (FHWA) and has become a major data product for the larger transportation community. This presentation will provide some insight on CTA’s role in developing the FAF Origin-Destination database, including: its relationship with the Census’s Commodity Flow Survey, how it was constructed, what limits that users need to consider when using the data, etc.  Some new changes impacting the forthcoming FAF release 4 will also be discussed.
