Top three things to fix
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
3354 of 3363 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.
Fixing this covers 3,354 of 3,363 stops, nearly all of them.
Effort: A column in stops.txt; your scheduling software likely has it.
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.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
This one is about the feed as a whole, so there is no share of it to count.
Effort: A small file for most flat-fare systems.
Delete the empty calendars or set their service days.
Some service calendars have no days of the week switched on. Trips tied to these calendars never run; they are dead data that can mask real schedule problems.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
Effort: A few minutes in your scheduling software.
Riders and need behind these fixes
- Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
- The served-area need overlays cover the United States and Canada, so none of them applies to this feed.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
