FAF² Highway Link and Truck Data and Documentation: 2002 and 2035

The FAF estimates commodity movements by truck and the volume of long distance trucks over specific highways. Models are used to disaggregate interregional flows from the Commodity Origin-Destination Database into flows among individual counties and assign the detailed flows to individual highways. These models are based on geographic distributions of economic activity rather than a detailed understanding of local conditions. While the FAF provides reasonable estimates for national and multi-state corridor analyses, FAF estimates are not a substitute for local data to support local planning and project development.

If you have Geographic Information Systems (GIS) software:

1. Download the appropriate network files for either ESRI or TransCad products.
2. Import the appropriate data files under the FAF output heading.
