The following Open Source tools are available to test feeds in the GTFS format.
Feed validators
Before publishing, validate your GTFS feeds in order to catch errors. A number of different validation tools exist. Some tools check individual feeds while others integrate into software.
GTFS-static feed validators
- MobilityData gtfs-validator: Verifies feed conformity to the official GTFS specification. At present, the software supports the validation of file structure and is ready for semantic validation. This tool is under active development.
For software developers
- Conveyal's gtfs-lib library: Contains validation functionality.
GTFS-realtime feed validators
- GTFS-realtime Validator: A tool to verify whether your real-time feed data correctly matches your GTFS dataset and contains all required information. Created and maintained by the Center for Urban Transportation Research at the University of South Florida in collaboration with MobilityData.
For software developers
- gtfs-realtime-validator-lib: Integrates GTFS-realtime validation rules into software.
