18251 of 18251 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. 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.)

Some rider-facing names are in ALL CAPS or all lowercase.

ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.

Fix: Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE'). (Often a bulk fix in your scheduling software.)

2554 of 2554 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.)

Some scheduled trips move faster between stops than a bus can.

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

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

Some stops sit far from the route line, going by the feed's own distance values.

Trip planners may draw the route down the wrong streets or point riders to the wrong corner.

Fix: Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree. (Usually an export-tool fix, not hand editing.)

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

Trip planners may draw the bus route through the wrong streets or point riders to the wrong corner.

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.)

Two or more routes share the same name.

Riders can't tell the routes apart in apps.

Fix: Give each route a distinct short or long name. (One field per route.)

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.)

Service data runs out in 12 day(s).

When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.

Fix: Re-export with a validity window that reaches at least 60 days out. (One 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.)

About 2517 stop names are written in ALL CAPS.

Mixed-case names are easier to read in apps and are read more naturally by screen readers.

Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)

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

The sign should tell riders where the bus 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.)
