Pathway unreachable location (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

5192 of 6529 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.)

3143 of 41479 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 stops exist in the feed but no trip ever stops at them.

Riders may walk to a stop where no transit vehicle 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.)

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

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 route long names repeat the route's short name inside them.

Apps show both names together, so riders see the number twice, like '5 5 Downtown'.

Fix: Drop the short name from route_long_name and keep the long name descriptive, like 'Downtown via 5th Ave'. (One field per flagged route.)

Validator rule: route_long_name_contains_short_name · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

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.)

Validator rule: duplicate_route_name · 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.)

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.)

Service data runs out in 29 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.)

Validator rule: scorecard_feed_expiring_soon · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices 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.)

Validator rule: scorecard_missing_feed_info_dates · 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.)

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

This feed describes station pathways, without an elevator route described.

Riders can be routed through the station, and wheelchair users can see whether a step-free route exists.

Fix: If the station has an elevator, add it as a pathway so wheelchair users can find the step-free route. (One pathway per elevator.)

Validator rule: scorecard_station_pathways

Unused station (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Validator rule: unused_station · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

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 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.)

Validator rule: unknown_column · Read the fix guide · 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.)

Validator rule: unknown_file · 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).

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.)
