The Traveler Analysis Framework (TAF) is the Federal Highway Administration’s (FHWA) first attempt at estimating long distance passenger travel. For this effort, FHWA defines long distance passenger travel as trips greater than 100 miles by various modes (highway (automobile and bus), air, and rail). The TAF integrates data from a variety of sources to create a comprehensive set of trip tables for long distance passenger movements at the county (or equivalent) to county (or equivalent) level. The TAF provides person trip flows for the base year of 2008 and future year 2040. These preliminary or “beta-version” data are deemed to be the starting point for any organization to use for their analysis. FHWA requests that data users only use the data as the starting point and proceed with enhancement. FHWA also requests that users share your enhancement techniques and results with FHWA. FHWA plans to improve and enhance these data in the future, and user feedback will greatly assist FHWA with that effort.
In the creation of these trip tables, FHWA wants to thank the Office of the Secretary of Transportation for providing funding support for this work. FHWA would also like to thank the expert panel it assembled to help guide the direction of the project. The expert panel included members from other US DOT modal administrations (FAA and FRA), state DOTs, MPOs, academia, associations, and private sector transportation interests (particularly for the rail and bus travel modes). These members provided technical assistance to the project’s contractor team and reviewed results for reasonableness.
Guidance for using the trip tables.
For all .csv and .dbf tables:
Column A: Origin FIPS (Note: The last 3 digits of the FIPS codes represent the county and the first 1 or 2 digits represent the state (the leading 0 has been removed for state FIPS codes between 01 and 09). As an example, FIPS Code 1001 represents Autauga County, Alabama.
Column B: Destination FIPS (Note: The last 3 digits of the FIPS codes represent the county and the first 1 or 2 digits represent the state (the leading 0 has been removed for state FIPS codes between 01 and 09). As an example, FIPS Code 1001 represents Autauga County, Alabama.
Column C: Number of Annual Person Trips for the year (either for 2008 or 2040)
The air, rail, and bus trip tables include person trips for all purposes. For automobile person trips, there are tables for business trips and non-business trips (for .dbf files, XXautobs.dbf files are business trip files and XXautonb.dbf are non-business trip files where XX represents the table year (2008 or 2040).

Each .zip file contains the corresponding trip tables in .csv, .mtx, and .dbf format.
