Top three things to fix
Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).
31 of 31 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
Effort: Often one default setting in your export.
Agencies here usually clear this within about 1 week (based on 5 observed fixes).
Remove retired stops from the export, or add them back to the trips that should serve them.
Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.
Effort: A review pass in your scheduling software.
Agencies here usually clear this within about 1 week (based on 11 observed fixes).
Check the flagged stop times for transposed minutes.
Some scheduled trips travel implausibly fast between stops. Usually a typo'd stop time; riders get impossible arrival estimates.
Effort: A few minutes per flagged trip.
Agencies here usually clear this within about 2 weeks (based on 6 observed fixes).
NTD certification readiness: Ready
Published at a public URL, valid, and current: the three things the NTD GTFS requirement asks of a feed all hold here. Only your own D-10 certification makes that official; this is a heads-up, not a determination.

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
