Everything we checked

• Warning24290 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)

• Warning6388 instances

  6388 of 6388 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)

• Warning48 instances

  48 of 351 trips scheduled during the sampling window had no live predictions.

  Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

  Fix: Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs. (A vendor data-mapping question.)

  Agencies here usually clear this within about 1 week (based on 84 observed fixes).

• Warning29 instances

  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.)

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

• Warning7 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)

• Warning4 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).

• Warning2 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).

• 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).

  Unsorted stop times (flagged by the MobilityData validator).

  See the linked rule for what this affects.

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

• Info6366 instances

  About 6366 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)

• Info6 instances

  Service window outside feed period (flagged by the MobilityData validator).

  See the linked rule for what this affects.

  Fix: Review the rule documentation for 'service_window_outside_feed_period' 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 17 observed fixes).

  Validator rule: service_window_outside_feed_period · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules 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.

• 23 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (1, 12, 26, 28X, 29, 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.

• 6257 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("KEEPORT DR + YOUNGRIDGE", "BROWNSVILLE RD + NOBLES LN", "BROWNSVILLE RD + THE BOULEVARD", and more).

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