Some rows in stop_times.txt leave the timepoint column blank.

That column says whether a time is a real checkpoint or an estimate. Blank leaves apps guessing, and they may show your estimates as promises.

Fix: Set timepoint=1 on stops that are real time checks and 0 on the rest. If every published time is a scheduled one, mark them all 1. (Usually one export setting.)

6729 of 6729 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.)

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.)

806 of 806 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 name and description for route (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Finding code: same_name_and_description_for_route · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Missing bike allowance (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Some service calendars have no days of the week switched on.

Trips tied to these calendars never run; they are dead data that can mask real schedule problems.

Fix: Delete the empty calendars or set their service days. (A few minutes in your scheduling software.)

Finding code: service_has_no_active_day_of_the_week · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Some service calendars in the feed have already ended.

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.)

3 of 32 trips scheduled during the sampling window had no live predictions.

Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

Fix: Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out. (A vendor data-mapping question.)

feed_info.txt lists no contact email and no contact URL.

Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.

Fix: Add feed_contact_email or feed_contact_url to feed_info.txt. (One field, set once in export settings.)

Finding code: missing_feed_contact_email_and_url · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

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.)

Finding code: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)

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 to link entrances, platforms, and elevators. Give each one a level. (Worth it for multi-level or large stations; flat stops don't need it.)

About 789 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.)

The feed has a stretch of two weeks or more with no service running.

A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.

Fix: Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar. (A review of your calendar dates.)

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.)

Finding code: trip_headsign_matches_intermediate_stop · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

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.)

Finding code: unknown_column · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

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

App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.

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