Chapel Hill Transit (CHT)

Stop time timepoint without times (flagged by the MobilityData validator).

See the linked rule for what this affects.

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

Service data ended 578 day(s) ago.

When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

Fix: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)

1529 of 1529 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.)

538 of 538 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.)

522 of 1529 trips lack rider-facing destination or direction text.

When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.

Fix: Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign. (Usually one value per route pattern in your scheduling source.)

Some service calendars in the feed have already ended.

Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.

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

This feed's service calendar runs out within the next 7 days.

When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.

Fix: Export and publish an updated GTFS feed that covers at least the next 30 days of service. (Usually a re-export from your scheduling software.)

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.

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.)

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.)

This feed describes flexible (demand-responsive) service but has no booking_rules.txt.

Riders can see the service area but not how or when to reserve a trip, so they can't actually use the service.

Fix: Add booking_rules.txt saying how far ahead and how to book (phone, app, or web). (A small file; one rule often covers the whole service.)

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.)

Finding code: unknown_column · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Some service dates fall outside the date window set in feed_info.txt.

feed_info.txt should span every day your service runs, so apps know when the data applies.

Fix: Widen feed_start_date and feed_end_date to cover all service dates, or fix the dates that fall outside. (Two fields in feed_info.txt, or one export setting.)

Finding code: service_window_outside_feed_period · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

The feed includes a file that is not part of the GTFS spec.

Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.

Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)
