Frequently Asked Questions
What is GTFS data?
General Transit Feed Specification (GTFS) is an open data format for public transit schedules and geographic information. Created by Google and TriMet, it enables transit agencies to publish interoperable data for applications, trip planners, and mobility analytics tools.
What is the difference between enhanced and source data?
Source data is the original GTFS feed obtained from the transit agency or official provider. The enhanced version has been processed to fix errors, remove inconsistencies, and ensure compliance with GTFS specifications. We recommend the enhanced version for production applications.
Can I use this data in my application?
Data usage depends on the license specified by the original provider. Check the license information in the download section. Many GTFS feeds use open data licenses that allow free use with attribution. Always verify the license terms before integration.
How do I validate a GTFS feed?
Each feed includes a validation report documenting errors and warnings. You can also use the MobilityData GTFS Validator for independent validation. Enhanced feeds have already been processed to resolve the most critical validation issues.
