Frequently Asked Questions
What is GTFS data?
GTFS, the General Transit Feed Specification, is the open format transit agencies use to publish schedules, stops and route shapes. Trip planners, routing engines and analytics tools read it directly.
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. API plans include source data only. Enhanced data requires a separate request through the data request form. Request access through the form →
Can I use this data in my application?
Source-data use depends on the licence set by the publisher; check it before integration. Enhanced and custom data is supplied under terms agreed for your coverage, delivery, and intended use.
How do I validate a GTFS feed?
Every feed here ships with a validation report of errors and warnings. For an independent check, run the MobilityData GTFS Validator. The enhanced feed has the critical issues resolved.
All data comes from public sources. If a file was posted in error, carries a wrong licence or lacks attribution, we will fix it.
