Yolo County Transportation District (Yolobus)
Grade F · 55.4 / 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:
Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.
Service data ended 158 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.
Estimated effort: Usually one export setting; export on a schedule so it never lapses again.
Agencies here usually clear this within about 1 week (based on 18 observed fixes).
Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).
743 of 743 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).
Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Estimated effort: A small file for most flat-fare systems.
