Call-prep brief · checked 2026-10-17

Denali National Park Courtesy Shuttle

Grade B · 85.8 / 100

Unchanged since 2026-10-16.

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the NTD details line up. Each fix is framed as a next step, not a failure.

What changed since the last check

  • Correctness no change
  • Freshness no change
  • Rider experience no change

Top three things to fix

  1. Publish the calendar for the current or next service period and set feed_info feed_end_date past it.

    This seasonal service has no published calendar. The last one ended 27 day(s) ago. Between service periods this is normal. But if buses are running with no published calendar, trip planners show nothing.

    This one is about the feed as a whole, so there is no share of it to count.

    Effort: One export when the next period's schedule is set.

  2. Remove past service periods the next time you export the feed.

    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.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: One setting in most export tools.

Riders and need behind these fixes

  • This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
  • Alaska as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-12.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

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.
