National Transit Database

The National Transit Database (NTD) is the Federal Transit Administration’s (FTA’s) primary national database for statistics on the transit industry.  Recipients of Federal transportation funds are required to report a wide range of agency data on an annual basis.  Given the level of data reported, these are typically published more than a year after the reporting period.
