Everything we checked

• Error64 instances

  Trip distance exceeds shape distance (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

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

• Error1 instance

  Service data ended 397 day(s) ago.

  When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

  Fix: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)

  Agencies here usually clear this within about 1 week (based on 18 observed fixes).

• Error1 instance

  The trip updates realtime feed failed during sampling.

  When this feed is down, riders see scheduled times presented as if they were live.

  Fix: Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)

  Agencies here usually clear this within about 1 week (based on 11 observed fixes).

• Error1 instance

  The vehicle positions realtime feed failed during sampling.

  When this feed is down, riders see scheduled times presented as if they were live.

  Fix: Check the vehicle positions endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)

  Agencies here usually clear this within about 1 week (based on 9 observed fixes).

• Error1 instance

  The service alerts realtime feed failed during sampling.

  When this feed is down, riders see scheduled times presented as if they were live.

  Fix: Check the service alerts endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)

  Agencies here usually clear this within about 1 week (based on 5 observed fixes).

• Warning3460 instances

  3460 of 3460 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.)

  Validator rule: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

• Warning2901 instances

  2901 of 2901 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 (most small-agency fleets are 100% accessible, so this is often a single default). (Often one default setting in your export.)

  Agencies here usually clear this within about 1 week (based on 5 observed fixes).

  Validator rule: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

• Warning1072 instances

  Stop too far from shape using user distance (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

  Agencies here usually clear this within about 1 week (based on 6 observed fixes).

• Warning187 instances

  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.)

  Agencies here usually clear this within about 2 weeks (based on 6 observed fixes).

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

• Warning26 instances

  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.)

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

• Warning25 instances

  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.)

  Agencies here usually clear this within about 2 weeks (based on 8 observed fixes).

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

• Warning9 instances

  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.)

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

• Warning7 instances

  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.)

  Agencies here usually clear this within about 2 weeks (based on 6 observed fixes).

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

• Warning3 instances

  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.)

  Agencies here usually clear this within about 1 week (based on 61 observed fixes).

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

• Warning1 instance

  This feed's service calendar runs out within the next 7 days.

  When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.

  Fix: Export and publish an updated GTFS feed that covers at least the next 30 days of service. (Usually a re-export from your scheduling software.)

  Agencies here usually clear this within about 1 week (based on 16 observed fixes).

  Validator rule: feed_expiration_date7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

• Warning1 instance

  Missing feed contact email and url (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

  Agencies here usually clear this within about 1 week (based on 6 observed fixes).

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

• Warning1 instance

  Many of the feed's trips don't run at all in the next 7 days.

  It usually means old service periods are still in the export, making the feed bigger and harder to check.

  Fix: Trim past service periods the next time you export. (One setting in most export tools.)

  Agencies here usually clear this within about 1 week (based on 31 observed fixes).

  Validator rule: trip_coverage_not_active_for_next7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

• Warning1 instance

  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)

• Info1 instance

  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 with your feed, so problems linger.

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

  Agencies here usually clear this within about 1 week (based on 10 observed fixes).

Beyond the grade

Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.

• 3425 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("S 5th @ W Muhammad Ali", "4th @ Market", "4th @ W Main", and more).

  Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
