Nitelink (Dublin Bus)

105 of 105 trips don't say whether the vehicle is wheelchair accessible.

Even with accessible stops, riders need to know the bus itself can take them.

Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)

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.

Fix: Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE'). (Often a bulk fix in your scheduling software.)

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.

Fix: Delete the empty calendars or set their service days. (A few minutes in your scheduling software.)

Many of the feed's trips don't run at all in the next 7 days.

It usually means old service periods are still in the export, making the feed bigger and harder to check.

Fix: Trim past service periods the next time you export. (One setting in most export tools.)

The feed contains no fare information.

Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

Fix: 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. (A small file for most flat-fare systems.)

Some trip headsigns name a stop along the way, not the final destination.

The sign should tell riders where the bus ends up, so a midpoint name can send them the wrong way.

Fix: Set trip_headsign to the trip's last stop or its overall destination. (Usually a bulk edit in your scheduling software.)

Feed valid beyond total service window (flagged by the MobilityData validator).

See the linked rule for what this affects.

Future calendar (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'future_calendar' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
