Service Description: The Travel Time to Work dataset was compiled using information from December 08, 2022 and updated September 01, 2023 from the Bureau of Transportation Statistics (BTS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The Travel Time to Work table from the 2021 American Community Survey (ACS) (5-year estimates) was joined by 2020 tract-level shapefiles for all 50 States, District of Columbia and Puerto Rico provided by the Census Bureau. A new file was created that combines the demographic variables from the former with the cartographic boundaries of the latter. The demographic variables contain count estimates for travel time to work within certain travel time bands, by Census tract, the shapefile allows these values to be visualized on a map. Travel time bands were condensed in order to have fewer variables. Percentage values for the count estimates were calculated and added, with workers 16 years and over who did not work at home as the denominator.
