A General Transit Feed Specification (GTFS) Realtime feed allows you to provide current information about your transit service to application developers, including Google. GTFS-Realtime is designed for easy implementation and compatibility with the route and schedule information in your GTFS feed. Because of this, it can provide the most accurate and useful passenger information possible.
How to check your eligibility
For Google to provide live updates on your transit fleet, you first need to make a working GTFS static feed available through Google Maps. Learn more about GTFS modeling with Google Transit.
