What is GTFS?

GTFS is an acronym for the General Transit Feed Specification. GTFS defines a common format for public transportation schedules and associated geographic, fare, and service calendar information. Learn more by reading the documentation for GTFS.

GTFS data is used in many applications that present public transportation information. The data is also analyzed by transportation planners and researchers.
