Connecticut Transit
Grade F · 53.6 / 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 trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

Estimated effort: Usually a vendor support ticket.
Agencies here usually clear this within about 1 week (based on 11 observed fixes).
