Top three things to fix
Correct feed_end_date in feed_info.txt. Set it to 2023-08-12, the last day in your calendar, or to the last day your schedule is reliable.
feed_info.txt says this feed ends on 2023-06-01. Your service calendar runs to 2023-08-12. The GTFS standard tells apps to trust a feed only up to its end date. So apps may stop showing your service on the earlier date, even though the calendar goes on.
This one is about the feed as a whole, so there is no share of it to count.
Effort: One field in feed_info.txt, often an export setting.
Add the required column named in the finding to the flagged file.
A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.
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: Often an export setting; ask your vendor if it recurs.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
4 of 4 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 all 4 stops in the feed.
Effort: A column in stops.txt; your scheduling software likely has it.
Riders and need behind these fixes
- This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
- Colorado as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
