Everything we checked

• Error927 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)

• Error108 instances

  Some trips have stop times whose distances along the route go backwards.

  Apps can show buses jumping backwards or mis-order stops.

  Fix: Re-generate shape distances in your export; flag to your vendor if it persists. (Usually an export-tool fix, not hand editing.)

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

• Warning29289 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)

• Warning22305 instances

  22305 of 22305 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)

• Warning4059 instances

  4059 of 6977 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)

• Warning445 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).

• Warning183 instances

  Same name and description for stop (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

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

• Warning176 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)

• Warning54 instances

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

  See the linked rule for what this affects.

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

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

• Warning39 instances

  39 of 22305 trips have no headsign.

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

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

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

• Warning23 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)

• Warning18 instances

  Some route colors don't contrast with their text color.

  Route badges get hard to read, most of all for riders with low vision.

  Fix: Pick a darker/lighter route_text_color for the flagged routes. (One field per route.)

  Validator rule: route_color_contrast · 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 30 days.

  If a new feed isn't published before it ends, trip planners will drop your agency and riders will see no service.

  Fix: Schedule a feed re-export now so the new calendar is live well before the current one ends. (Usually a re-export from your scheduling software.)

  Agencies here usually clear this within about 1 week (based on 24 observed fixes).

  Validator rule: feed_expiration_date30_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

• Warning1 instance

  Route long name contains short name (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

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

• Warning1 instance

  Stops match shape out of order (flagged by the MobilityData validator).

  See the linked rule for what this affects.

  Fix: Review the rule documentation for 'stops_match_shape_out_of_order' 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: stops_match_shape_out_of_order · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

• Warning1 instance

  Service data runs out in 10 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.)

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

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

• Info6941 instances

  About 6941 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 (e.g. 'Main St & 2nd Ave'). (Often a bulk fix in your scheduling software.)

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

• Info5 instances

  Unknown file (flagged by the MobilityData validator).

  See the linked rule for what this affects.

  Fix: Review the rule documentation for 'unknown_file' 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: unknown_file · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

• Info1 instance

  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.)

Beyond the grade

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

• 75 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (001, 003, 005, 009, 013, and more).

  Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.

• 6836 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("FOREST @ SHEPHERD - E - NS", "WALNUT HILL @ RAMBLER - W - MB", "WALNUT HILL @ GREENVILLE - E - MB", and more).

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