Call-prep brief · checked 2026-10-07

Roosevelt Island Operating Corporation Tramway (RIOC Tramway)

Grade A · 92.9 / 100

Unchanged since 2026-10-06.

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. 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.

    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: Varies.

  2. Add feed_contact_email or feed_contact_url to feed_info.txt.

    feed_info.txt lists no contact email and no contact URL. Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.

    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 field, set once in export settings.

  3. Add feed_contact_email to feed_info.txt.

    feed_info.txt has no technical contact (feed_contact_email or feed_contact_url). App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.

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

    Effort: One field.

Riders and need behind these fixes

  • This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
  • New York as a whole measures moderate 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 2026-10-05.

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

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.

Current Ready

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.
