GTFS Realtime Resources

Applications

The OneBusAway application suite has support for both GTFS-realtime import and export. The application suite can be used to provide a high-level API from low level GTFS and GTFS-realtime data feeds, for example.

Tools and Libraries

We provide a number of libraries and tools for working with GTFS-realtime data:

• onebusaway-gtfs-realtime-api - a set of Java classes generated from the GTFS-realtime Protocol Buffer spec that allow you to produce and consume raw GTFS-realtime data.
• onebusaway-gtfs-realtime-exporter provides a simple library to assist in sharing GTFS-realtime data.
• onebusaway-gtfs-realtime-from-siri-cli provides a command-line tool for converting SIRI real-time data into GTFS-realtime.
• onebusaway-gtfs-realtime-from-nextbus-cli provide a command-line tool for converting NextBus API real-time data into GTFS-realtime.
• onebusaway-gtfs-realtime-munin-plugin provides a Munin plugin for logging information about a GTFS-realtime feed.
• onebusaway-gtfs-realtime-nagios-plugin provides a Nagios plugin for monitoring a GTFS-realtime feed.

Also see a number of third-party tools here.
