A GTFS dataset is a .zip file composed of several text files. The process of viewing, editing, and saving these files may look different depending on what kind of computer and software you are using.

See a step-by-step on how to navigate a GTFS file.

Although the amount of files present in some GTFS datasets can seem overwhelming at first, only six are actually required. Understanding what these six "core" files of GTFS do and how they relate to one another is a great first step in grasping the essentials of your data.

See each file, what it contains, and why it matters.

GTFS is an ever-expanding data standard that sees ongoing development for supplemental use-cases like demand-responsive transportation. Such additional functionalities are encapsulated in the various GTFS extensions that have either already been officially adopted into the standard or have been proposed and are awaiting adoption.

A static fetch link is a permanent URL where your static GTFS file is stored. Typically, it is hosted either on your agency’s website or by your vendor if you contract with one for your GTFS.

GTFS can be used in collaboration with scheduling/runcutting software, CAD/AVL tools, and even signage and annunciator hardware.
