BAS.MY Kangar

Grade F · 52.7 / 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. Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

    The trip updates realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

    Effort: Usually a vendor support ticket.

  2. Check the service alerts endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

    The service alerts realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

    Effort: Usually a vendor support ticket.

  3. Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.

    17 of 17 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

    Effort: A vendor data-mapping question.
