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 defines a common format for transit agencies to publish their data, enabling developers to build interoperable transit applications, trip planners, and mobility analytics tools.
What is the difference between enhanced and source data?
Source data is the original GTFS feed obtained directly from the transit agency or official provider. The enhanced version has been processed by our team to fix common errors, remove inconsistencies, and ensure compliance with GTFS specifications. We recommend using 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 above. Many GTFS feeds are published under open data licenses that allow free use with attribution. Always verify the license terms before integrating data into your project.
How do I validate a GTFS feed?
Each feed includes a validation report that documents errors and warnings. You can also use tools like the MobilityData GTFS Validator to independently validate the data. Our enhanced feeds have already been processed to resolve the most critical validation issues.
