ACTV Venezia (bus and tram)

Missing timepoint value (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

35040 of 35040 trips don't say whether the vehicle is wheelchair accessible.

Even with accessible stops, riders need to know the transit vehicle 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.)

1997 of 1997 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.

Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

Some stops exist in the feed but no trip ever stops at them.

Riders may walk to a stop where no transit vehicle is scheduled to arrive.

Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)

Missing feed contact email and url (flagged by the MobilityData validator).

Some files leave out fields that GTFS asks for but does not require.

Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.

Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)

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.)

Trip headsign matches intermediate stop (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Some files contain columns that are not part of the GTFS spec.

Harmless to riders, but apps ignore these columns and they can hide typos in real column names.

Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)

feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).

Trip-planning apps and regional data coordinators have nobody to email when they spot a problem with your feed, so problems linger.

Fix: Add feed_contact_email to feed_info.txt. (One field.)
