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?
The source feed is what the agency published. The enhanced feed is the same data after BusMaps fixed the errors and inconsistencies and checked it against the GTFS specification. Use the enhanced feed in production.
Can I use this data in my application?
That depends on the licence the publisher set; you find it next to the files above. Most GTFS feeds allow free use with attribution. Check the licence before you integrate.
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.
