National Transportation Data Archive
The National Transportation Data Archive (NTDA) is intended to preserve and provide access to high-value, discrete datasets, created or aggregated by the Bureau of Transportation Statistics (BTS). The NTDA also seeks to preserve other transportation research or statistical data sets, created by non-US DOT entities, within the borders of the United States, its territories, and possessions.
