Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps Get the validator from github.com/MobilityData/gtfs-realtime-validator (Java-based, ships as a library plus a webapp for URL-based checks) Supply both the static GTFS feed and the GTFS-Realtime feed URL — many realtime rules require cross-referencing against the static schedule Run the webapp (or batch mode) to validate TripUpdates, VehiclePositions, and Alerts against the protobuf schema and best-practices rules Review flagged issues such as stale timestamps, missing required fields, or trip/stop IDs that don't resolve against the static feed Re-run validation on a recurring schedule since realtime feeds can regress even when the paired static feed doesn't change Known gotchas This is a separate project/repo from the static gtfs-validator — don't point at the schedule validator for realtime feed problems Validation quality depends on loading an accurate, matching static feed alongside the realtime feed; a mismatched static feed produces false positives
