Riders and need behind these fixes
- This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
- California as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
