Block trips with overlapping stop times (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

11146 of 11146 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.)

Some internal IDs use characters outside the basic text set.

These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.

Fix: Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language. (A planned ID change, not a quick text cleanup.)

2255 of 2255 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.)

Finding code: scorecard_wheelchair_boarding_unknown · Read the fix guide for scorecard_wheelchair_boarding_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

Some live predictions are more than 30 minutes away from the schedule.

Differences that large usually mean predictions are keyed to the wrong trips, not that buses are that late.

Fix: Spot-check the flagged predictions against what buses actually did; raise trip-matching with your AVL vendor. (A vendor data-mapping question.)

Finding code: scorecard_rt_predictions_implausible

The feed contains route shapes no trip uses.

Harmless to riders, but it bloats the feed and suggests stale export data.

Fix: Turn on 'remove unused shapes' (or the like) in your export tool. (One setting.)

67 of 83 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.)

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 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.)

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

A file GTFS asks for (usually feed_info.txt) is missing.

feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.

Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)

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

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

Trip planners can draw the bus 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.)

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

feed_info.txt is missing its start/end dates (the file itself is absent)

Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)

Finding code: scorecard_missing_feed_info_dates · Read the fix guide for scorecard_missing_feed_info_dates · 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 for scorecard_no_fare_data · 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 127 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.)

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 for unknown_column · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

The feed includes a file that is not part of the GTFS spec.

Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.

Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)

Finding code: unknown_file · Read the fix guide for unknown_file · 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.)
