El Dorado County Transit Authority
Grade B · 84.1 / 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:
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
112 of 128 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.
Estimated effort: A column in stops.txt; your scheduling software likely has it.
Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).
135 of 135 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).
Check the flagged stop times for transposed minutes.
Some scheduled trips travel implausibly fast between stops. Usually a typo'd stop time; riders get impossible arrival estimates.
Estimated effort: A few minutes per flagged trip.
Agencies here usually clear this within about 2 weeks (based on 6 observed fixes).
Trillium produces and hosts this feed as a service. These changes are made on their side: send the fix list to your Trillium contact and they apply it and republish.
