NYC Ferry
Grade C · 77.0 / 100
Unchanged since 2026-07-08.
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:
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.
Agencies here usually clear this within about 1 week (based on 9 observed fixes).
Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.
2 of 2 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.
Estimated effort: A vendor data-mapping question.
Agencies here usually clear this within about 1 week (based on 84 observed fixes).
Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).
723 of 723 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.
Agencies here usually clear this within about 1 week (based on 5 observed fixes).
Where this agency stands
Ahead of 74% of all tracked agencies, and ahead of 71% of small agencies nationwide.
