General Transit Feed Specification (GTFS)

The General Transit Feed Specification (GTFS) is an Open Standard used to distribute relevant information about transit systems to riders. It allows public transit agencies to publish their transit data in a format that can be consumed by a wide variety of software applications.

GTFS consists of two main parts: GTFS Schedule and GTFS Realtime.

GTFS Schedule

GTFS Schedule is a feed specification that defines a common format for static public transportation information. It is composed of a number of text (.txt) files that are contained in a single ZIP file. Each file describes a particular aspect of transit information: stops, routes, trips, fares, etc.

GTFS Realtime

GTFS Realtime is a feed specification that allows public transportation agencies to provide up-to-date information about current arrival and departure times, service alerts, and vehicle position, allowing users to smoothly plan their trips.
