Top three things to fix

1. Review the rule documentation for 'invalid_phone_number' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Invalid phone number (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

2. Populate trip_headsign to match what the bus displays.

   188 of 280 trips have no headsign. Riders at the stop can't tell which direction a bus is going.

   Effort: Usually a bulk edit in your scheduling software.

3. Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').

   Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.

   Effort: Often a bulk fix in your scheduling software.

Service data covers the next 368 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.
