GTFS Feed Development & Management
Build, manage and distribute GTFS feeds - All from a single intuitive UI
The General Transit Feed Specification (GTFS) is the standard data format for publishing public transportation schedules and associated geographic information.
A complete GTFS feed includes multiple text files (.txt) covering service data such as:
agency.txt – Agency details
routes.txt – Routes and modes of service
trips.txt – Trips associated with each route
stop_times.txt – Stop sequences and arrival/departure times
stops.txt – Stop locations with geospatial coordinates
calendar.txt / calendar_dates.txt – Service schedules and exceptions
shapes.txt – Geospatial paths for routes
More
In addition to static feeds, many agencies now also publish GTFS-Realtime feeds to provide vehicle positions, trip updates, and service alerts.
Building and maintaining accurate GTFS feeds require consistent data modeling, quality assurance, and ongoing updates.
TDS provides full end-to-end GTFS support including:
Feed Creation from Source Data
