Giant Forest Shuttle (Sequoia National Park)

What changed since the last check

No category changes since the last check.

Top three things to fix

1. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

   4 of 15 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.

   Effort: A column in stops.txt; your scheduling software likely has it.

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

   Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

3. Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt.

   Some route lines list the same point twice in a row. Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.

   Effort: Usually one export setting.

NTD GTFS readiness: Ready

Published at a public URL, valid, current, and identified with agency_id: the four feed checks for RY2026 all hold here. Only your own D-10 and P-50 filings make that official; this is a heads-up, not a determination.

agency_id provided Ready

agency.txt provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk each value on the P-50 form.

agency_id equals NTD ID (optional): Not checked yet. This feed provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk it on the P-50 form. The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
