2920 of 2920 trips don't say whether the vehicle is wheelchair accessible.

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

Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)

647 of 647 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.)

Same route and agency url (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'same_route_and_agency_url' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

Some stops sit far from the route line they belong to.

Trip planners may draw the transit vehicle route through the wrong path or point riders to the wrong boarding location.

Fix: Check the flagged stops' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced. (A few minutes per flagged stop.)

Some scheduled trips move faster between stops than a transit vehicle can.

Usually a typo'd stop time; riders get arrival times no transit vehicle can meet.

Fix: Check the flagged stop times for transposed minutes. (A few minutes per flagged trip.)

Between two distant stops, the times imply a speed no transit vehicle reaches.

A rider gets a trip plan that cannot happen. Live systems then report delays that are not real.

Fix: Check the two stop times for a wrong digit first. Then check whether a stop sits at the wrong coordinates, or a stop between them is missing. (Minutes per flagged trip once you open it.)

On some trips the stops fall along the route line in a different order than the schedule lists.

Trip planners can draw the transit vehicle doubling back or skipping ahead, which confuses riders reading the map.

Fix: Check the stop order and the shape direction in your scheduling software; the shape is often drawn backwards. (A few minutes per flagged trip.)

This feed's service calendar runs out within the next 30 days.

If a new feed isn't published before it ends, trip planners will drop your agency and riders will see no service.

Fix: Schedule a feed re-export now so the new calendar is live well before the current one ends. (Usually a re-export from your scheduling software.)

feed_info.txt says this feed ends on 2026-10-13. Your service calendar runs to 2027-10-04.

The GTFS standard tells apps to trust a feed only up to its end date. So apps may stop showing your service on the earlier date, even though the calendar goes on.

Fix: Correct feed_end_date in feed_info.txt. Set it to 2027-10-04, the last day in your calendar, or to the last day your schedule is reliable. (One field in feed_info.txt, often an export setting.)

The feed contains no fare information.

Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

Fix: Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead. (A small file for most flat-fare systems.)

Some service dates fall outside the date window set in feed_info.txt.

feed_info.txt should span every day your service runs, so apps know when the data applies.

Fix: Widen feed_start_date and feed_end_date to cover all service dates, or fix the dates that fall outside. (Two fields in feed_info.txt, or one export setting.)

Some trip headsigns name a stop along the way, not the final destination.

The sign should tell riders where the transit vehicle ends up, so a midpoint name can send them the wrong way.

Fix: Set trip_headsign to the trip's last stop or its overall destination. (Usually a bulk edit in your scheduling software.)

Future feed (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'future_feed' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
