Call-prep brief · checked 2026-07-18

Autotransporta direkcija (ATD) national routes

Grade F · 27.9 / 100

First check for this agency, so there is no trend yet.

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

What changed since the last check

No category changes since the last check.

Top three things to fix

  1. Add feed_start_date and feed_end_date to feed_info.txt and include calendar end dates in your export.

    Neither feed_info.txt nor the calendars state when service ends. Nobody can tell when this feed will go stale.

    Effort: Likely a one-time export setting.

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

    Invalid phone number (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

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

    10142 of 10142 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.
