The General Transit Feed Specification (GTFS) defines a common format for public transportation schedules and associated geographic information.

GTFS, first conceived by Bibiana McHugh, an IT Manager at the TriMet transit agency in the Portland metropolitan area (Oregon) was developed by Google and Portland TriMet, and originally known as the Google Transit Feed Specification.[1]

A GTFS feed is a collection of CSV files (with extension .txt) that model a public transit system's schedules, usually contained within a zip file. The files are sufficient to provide trip planning functionality, and to a greater extent power additional applications such as real-time information systems and service analysis.
