General Transit Feed Specification (GTFS)

GTFS is an open format, used by Google to combine schedule and route data from transit agencies with geographic data for use in applications, like Google Maps. Other software developers may be able to use this data for other applications.

Arlington Transit (ART) makes its schedule and route data freely available.

Download GTFS data below. Files are updated as changes are made.

General Transit Feed Specification Realtime (GTFS-realtime)

GTFS-realtime is a feed specification that allows public transportation agencies to provide realtime updates about their fleet to application developers. It is an extension to GTFS (General Transit Feed Specification), an open data format for public transportation schedules and associated geographic information. GTFS-realtime was designed around ease of implementation, good GTFS interoperability and a focus on passenger information. The specification was designed through a partnership of the initial Live Transit Updates partner agencies, a number of transit developers and Google. The specification was introduced and released under the Creative Commons Attribution 3.0 license in August 2011.
