California AV Trip Reporting

California is the only state represented in this trip tracker: its Public Utilities Commission requires AV passenger-service participants to report these trip and mileage data. CPUC data are updated quarterly. These California results do not describe AV activity nationwide.

Interpretation: SGO records do not identify the CPUC passenger-service program. The numerator can include Waymo testing or other operations that the denominator excludes. Reporting lags, alleged severity, and changes to SGO rules affect counts; these are descriptive proxies, not a comparable fleet safety rate. Serious/fatal is the highest alleged severity per crash, not the number of injured people. Report ID updates are reduced to the latest version; records sharing NHTSA’s Same Incident ID count once within Waymo’s reports. Airbag and injury information is self-reported and may change with later updates.

What Do Waymos Do Between Rides?

CPUC reporting lets us separate the miles and time between passenger trips. Period 1 covers the interval after a drop-off and before the next trip is accepted; Period 2 covers travel to the next pickup. Together, they show how much Waymo activity occurs without a passenger aboard.

Total Waiting Time
P1 hours: unassigned between trips, whether moving or stationary.
Waiting Time per Trip
A fleet-efficiency measure: P1 waiting hours divided by passenger trips.
VMT by Trip Period
Occupied, pickup, and unassigned / positioning miles.
Utilization of Vehicle Miles
Passenger-occupied share versus all miles without a passenger.
Estimated Stationary P1 Time
Sensitivity estimate assuming P1 movement averages 14 mph: waiting hours − (P1 miles ÷ 14 mph).

This is an assumption-based estimate, not directly reported parking time.
CPUC Periods: P1 = unassigned after a trip and before accepting the next trip; P2 = en route to pickup after accepting a trip; P3 = passenger aboard. Non-passenger VMT is P1 + P2. Estimated stationary P1 time uses a 14 mph assumed average moving speed and is not directly reported by CPUC.
