17096 of 17096 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.)

6363 of 17096 trips have no headsign.

Riders at the stop can't tell which direction a transit vehicle is going.

Fix: Populate trip_headsign to match what the transit vehicle displays. (Usually a bulk edit in your scheduling software.)

3216 of 4333 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 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.)

Some files leave out fields that GTFS asks for but does not require.

Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.

Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)

This feed models stations or entrances but has no pathways.txt.

Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.

Fix: Add pathways.txt connecting entrances, platforms, and any elevators, with a level for each. (Worth it for multi-level or large stations; flat stops don't need it.)

feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).

Trip-planning apps and regional data coordinators have nobody to email when they spot a problem with your feed, so problems linger.

Fix: Add feed_contact_email to feed_info.txt. (One field.)
