What is a GTFS trip?

GTFS, which stands for General Transit Feed Specification or (originally) Google Transit Feed Specification, defines a common format for public transportation schedules and associated geographic information.

How does GTFS work?

A GTFS feed is composed of a series of text files collected in a ZIP file. Each file models a particular aspect of transit information: stops, routes, trips, and other schedule data. The details of each file are defined in the GTFS reference. An example feed can be found in the GTFS examples.
