Everything we checked

• Warning921 instances

  921 of 921 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.)

• Warning921 instances

  921 of 921 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).

• Warning172 instances

  172 of 921 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.)

• Warning1 instance

  This feed describes flexible (demand-responsive) service but has no booking_rules.txt.

  Riders can see the service area but not how or when to reserve a trip, so they can't actually use the service.

  Fix: Add booking_rules.txt saying how far ahead and how to book (phone, app, or web). (A small file; one rule often covers the whole service.)

• Info34 instances

  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.)

• Info11 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).

Beyond the grade

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

• Flex zones are published but no booking_rules.txt is present.

  Consider: Add booking_rules.txt with how far ahead and how to reserve (phone, app, or web).

• 5 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (Sunshine Shuttle Route A, The Link - Willowbrook A, The Link - Willowbrook B, Union Pacific/Salazar Park, Whittier Boulevard/Saybrook Park).

  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.

• 897 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Workman Mill Rd & Crossroads Pkwy", "Kella Ave & Kathleen Ave", "Pellissier Rd & Mardel Ave", and more).

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

Some fixes we can make for you

These are the safe mechanical fixes, applied to a copy of your feed. They change only what is certain and leave everything else untouched. Review the diff before you publish.

• Trimmed surrounding whitespace 1 change

  For example: 'route_long_name': 'Marina Del Rey Beach Bus ' -> 'Marina Del Rey Beach Bus'
