Everything we checked

• Warning546 instances

  546 of 546 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).

• Warning533 instances

  533 of 546 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.)

• Warning357 instances

  357 of 357 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.)

• 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.)

Beyond the grade

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

• 325 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Hwy 6 East & Heinz Rd", "Commerce Dr & Liberty Dr", "Scott Blvd & Systems Unlimited", and more).

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