NOTE: As weblinks are updated continually by transit agencies, some links submitted in Report Year 2023 may no longer work. The most up-to-date weblinks dataset is refreshed on a monthly basis: https://data.transportation.gov/Public-Transit/General-Transit-Feed-Specification-Weblinks/2u7n-ub22/about_data

As of Report Year (RY) 2023, FTA requires that reporters with fixed route modes create and maintain a public domain general transit feed specification (GTFS) dataset that reflects their fixed route service. This specification allows for the mapping and other geospatial data visualization and analyses of key transit elements such as stops, routes, and trips. At least one GTFS weblink is provided by the transit agency for each fixed route bus mode and type of service. These include all Rail modes as well as Bus, Bus Rapid Transit, Commuter Bus, Ferryboat and Trolleybus.

GTFS requires that an overarching compressed file contain, at a minimum, seven underlying text files: (a) Agency; (b) Stops; (c) Routes; (d) Trips; (e) Stop Times; (f) Calendar or Calendar Dates.txt; and (g) Feed Info.txt. An eighth file, Shapes.txt, is an optional file. FTA collects and publishes these links for further analysis using related GTFS files. FTA is not responsible for managing the websites that host these files, and users with questions regarding the GTFS data are encouraged to contact the transit agency.

In many cases, publicly hosted weblinks could not be provided (i.e., due to constraints within the transit agency), but the agency was able to produce a zip file of the required GTFS data. Demand Response, Vanpool, and other non-fixed route modes are excluded. The column "Alternate Format" indicates that the agency provided FTA a weblink in an alternate format with some justification for doing so. The file "Waived" indicates that no GTFS files were produced and FTA granted the agency a waiver from the requirement in Report Year 2023.

NTD Data Tables organize and summarize data from the 2023 National Transit Database in a manner that is more useful for quick reference and summary analysis. This dataset is based on the 2023 General Transit Feed Specification database file.
