• Error1 instance

  Service data ended 1262 day(s) ago.

  When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

  Fix: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)

  Validator rule: scorecard_feed_expired

• Warning461 instances

  461 of 461 stops don't say whether a wheelchair user can board there.

  Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

  Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

  Validator rule: scorecard_wheelchair_boarding_unknown · Read the fix guide

• Warning421 instances

  421 of 421 trips don't say whether the vehicle is wheelchair accessible.

  Even with accessible stops, riders need to know the bus itself can take them.

  Fix: Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default). (Often one default setting in your export.)

  Validator rule: scorecard_wheelchair_accessible_unknown · Read the fix guide

• Warning4 instances

  Some service calendars in the feed have already expired.

  Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.

  Fix: Remove past service periods the next time you export the feed. (One setting in most export tools.)

  Validator rule: expired_calendar · Read the fix guide

• Warning4 instances

  Some stops exist in the feed but no trip ever stops at them.

  Riders may walk to a stop where no bus is scheduled to arrive.

  Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)

  Validator rule: stop_without_stop_time · Read the fix guide

• Warning1 instance

  This feed's service calendar runs out within the next 7 days.

  When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.

  Fix: Export and publish an updated GTFS feed that covers at least the next 30 days of service. (Usually a re-export from your scheduling software.)

  Validator rule: feed_expiration_date7_days · Read the fix guide

• Warning1 instance

  Many of the feed's trips don't run at all in the next 7 days.

  It usually means old service periods are still in the export, making the feed bigger and harder to check.

  Fix: Trim past service periods the next time you export. (One setting in most export tools.)

• Info80 instances

  Some files contain columns that are not part of the GTFS spec.

  Harmless to riders, but apps ignore these columns and they can hide typos in real column names.

  Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)

• Info40 instances
