Top three things to fix
Review the rule documentation for 'same_name_and_description_for_stop' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Same name and description for stop (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Review the rule documentation for 'route_short_name_too_long' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Route short name too long (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
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.
NTD GTFS readiness: Ready
This feed looks ready for your NTD certification: published at a public URL, valid, and current. The official check is still your D-10 certification.
- Published Ready
- Published at a public URL.
- Valid Ready
- Passes validation with no errors.
- Current Ready
- Service data covers the next 67 days.
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.
