NYC Ferry

Grade B · 83.9 / 100

Unchanged since 2026-07-10.

What this grade measures

The quality of the schedule data this agency publishes for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.

Progress this period

No newly cleared items this period. The score and trend above reflect where the feed stands today.

What needs attention next

Three improvements, in priority order, each sized so the board can see what it is approving:

  1. Check the vehicle positions endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

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

    Estimated effort: Usually a vendor support ticket.

  2. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

    1661 of 1661 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Estimated effort: Often one default setting in your export.

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

    Missing bike allowance (flagged by the MobilityData validator). See the linked rule for what this affects.

    Estimated effort: Varies.
