<hr />
<div>===Definition===<br />
<br />
''from Google's [https://developers.google.com/transit/gtfs-realtime/ "What is GTFS-realtime?" guide'']:<br />
<br />
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.<br />
<br />
The specification was designed through a partnership of the initial Live Transit Updates partner agencies, a number of transit developers and Google. The specification is published under the Apache 2.0 License.<ref>https://developers.google.com/transit/gtfs-realtime/</ref><br />
<br />
===Components of GTFS-realtime===<br />
* [https://developers.google.com/transit/gtfs-realtime/guides/trip-updates Trip Updates] - Predictions of when the vehicle will arrive<br />
* [https://developers.google.com/transit/gtfs-realtime/guides/vehicle-positions Vehicle Positions] - Locations of vehicles<br />
* [https://developers.google.com/transit/gtfs-realtime/guides/service-alerts Service Alerts] - Notifications to users that there is a disruption in the network<br />
<br />
===How to provide GTFS-realtime===<br />
This is a stub section that needs to be developed. <br />
<br />
===Applications that consume GTFS-realtime data===<br />
''List is not comprehensive''<br />
* [[Google Maps]]<br />
* [[OpenTripPlanner]]<br />
* [[OneBusAway]]<br />

===GTFS-realtime validation===<br />
<br />
As of March 2017, there is no official public validation tool either endorsed by the GTFS-realtime community or provided by Google that validates that a GTFS-realtime feed contents are correct. <br />
<br />
However, a [https://github.com/CUTR-at-USF/gtfs-realtime-validator GTFS-realtime validation tool] is currently under development at the [https://www.cutr.usf.edu/ Center for Urban Transportation Research] at the [http://www.usf.edu/ University of South Florida] as part of a [http://nitc.trec.pdx.edu/ National Institute for Transportation and Communities (NITC)]-funded, based on early work from a 2015 Google Summer of Code project.<br />
