Security leads the whole lot we do at Waymo. This 12 months alone, Waymo has served over 700,000 ride-hailing journeys with public riders and no human driver. We couldn’t have hit that milestone with out placing security entrance and middle, and we’re working onerous to enhance the measurement, transparency, and efficiency of our fleet.
Our complete analysis — throughout greater than twenty security papers that we’ve revealed through the years to reinforce transparency — exhibits that the Waymo Driver performs safely throughout a spread of evaluations. Constructing on that work, we’ve revealed two new papers as we speak: one that compares the Waymo Driver’s crash charges to human drivers’ over our 7+ million rider-only miles from Phoenix, San Francisco, and Los Angeles; and one other that develops clear human crash benchmarks to allow such comparisons.
Our new analysis discovered that Waymo Driver efficiency led to a big discount within the charges of police-reported and injury-causing crashes in comparison with human drivers within the cities the place we function.
“These studies characterize a good-faith effort by Waymo to judge how the protection of its autonomous driving system compares with the protection of human driving. The outcomes are encouraging and characterize one step in our evolving understanding of autonomous driving security,” mentioned David Zuby, chief analysis officer of The Insurance coverage Institute for Freeway Security (IIHS) after reviewing the papers.
How the Waymo Driver compares to people
There’s no single metric that may present the protection of autonomous driving. We use a number of completely different analysis metrics and strategies aiming to get an entire image of security. Considered one of many metrics that can be utilized to observe the rider-only service after it has launched is the variety of automobile crashes per mile of driving in comparison with people.
Within the efficiency examine, we in contrast the Waymo Driver’s crash charges to human drivers’ on a number of completely different benchmarks. This examine is among the first to match total crash charges utilizing knowledge from absolutely autonomous operations solely, quite than a mixture of absolutely autonomous driving and testing with a human behind the wheel. Not like the latest analysis by Swiss Re that targeted on crashes leading to Waymo’s legal responsibility claims, this examine consists of all Waymo crashes, whatever the Waymo automobile’s function within the crash, and with any quantity of property injury. It additionally makes use of publicly obtainable knowledge, which permits different researchers to duplicate the outcomes.
Waymo’s knowledge was derived from crashes reported below NHTSA’s Standing Common Order (SGO), over 7.14 million absolutely autonomous miles pushed 24/7 by way of the top of October 2023 throughout Phoenix, San Francisco, and Los Angeles. That knowledge was then in comparison with related human crash charges leading to police studies, accidents, and/or property injury.
When contemplating all places collectively, in comparison with the human benchmarks, the Waymo Driver demonstrated:
- An 85% discount or 6.8 instances decrease crash price involving any harm, from minor to extreme and deadly instances (0.41 incidence per million miles for the Waymo Driver vs 2.78 for the human benchmark)
- A 57% discount or 2.3 instances decrease police-reported crash price (2.1 incidence per million miles for the Waymo Driver vs. 4.85 for the human benchmark)
Which means that over the 7.1 million miles Waymo drove, there have been an estimated 17 fewer accidents and 20 fewer police-reported crashes in comparison with if human drivers with the benchmark crash price would have pushed the identical distance within the areas we function.
When in comparison with crash charges in San Francisco, Phoenix, and Los Angeles, individually, the Waymo Driver considerably outperformed native respective human benchmarks as properly (although the comparability in LA doesn’t but have sufficient mileage to be statistically important). Notably, native human benchmarks diversified from one metropolis to a different — for instance, San Francisco had the best price of crashes the place an harm was reported with 5.55 incidents per million miles, which was roughly thrice larger than the nationwide common.

Normally, the Waymo Driver additionally demonstrated decrease property injury charges in comparison with the human benchmarks. Nevertheless, the benchmark charges themselves diversified significantly relying on the human knowledge supply, even throughout the identical location, so warning must be taken when deciphering these outcomes.
Producing a legitimate comparability of human and AV efficiency
Figuring out legitimate and comparable human crash benchmarks is essential for understanding autonomous driving know-how’s efficiency. Regardless of public accessibility of each human and autonomous automobile (AV) crash knowledge, evaluating the 2 comes with its share of challenges. Our benchmarking paper goals to make sure a good comparability between AV and human driving by addressing the most typical errors and biases and establishing legitimate benchmarks from the cities during which Waymo operates.
There are two necessary sources of statistical bias to manage for when evaluating human and autonomous driving. The primary is human crash underreporting. Whereas the info on human crashes that result in accidents or property injury is pretty sturdy, numerous human low-severity crashes — like hitting some highway particles or minor “fender benders” — are usually not reported to police. In distinction, AV firms report even probably the most minor crashes with a view to reveal the trustworthiness of autonomous driving on public roads. For instance, solely 21% of crashes that Waymo has reported to NHTSA to this point have resulted in a filed police report, whatever the occasion at fault.
The second is variations in driving situations and/or automobile traits. Public human crash knowledge consists of all highway varieties, like freeways, the place the Waymo Driver presently solely operates with an autonomous specialist behind the wheel, in addition to varied automobile varieties from industrial heavy automobiles to passenger and bikes.
These variations imply that changes have to be made to human crash knowledge earlier than evaluating it to AV crash charges. Simply as you wouldn’t examine biking in a road-race to mountain biking with out accounting for variations in altitude, terrain, and different elements, comparisons between human and autonomous driving must account for variations too.
P.c discount for the Waymo Driver in police-reported and any-injury-reported crashed automobile charges in comparison with human benchmarks
To verify the human crash knowledge is legitimate and comparable, the harm and property injury benchmarks in our 7.1 million mile examine both included underreporting changes for police-reported crashes or had been derived from naturalistic driving examine databases, which equip automobiles with sensors to file driving and usually tend to catch low-severity crashes. The methodology we used was primarily based on greatest practices from a literature evaluate of 12 previous research and 1 guide evaluating AV and human crash charges.
At Waymo, we imagine that worldwide standardization for legitimate evaluation of AV crash knowledge is required. We’re on the lookout for alternatives to have interaction the neighborhood of site visitors security specialists and requirements organizations to advance this work sooner or later.
Our complete method to security
Whereas being safer than human drivers in combination is a crucial facet of AV security, it’s not enough by itself. The evaluation of crash charges is only one amongst many strategies used to judge the Waymo Driver’s efficiency, akin to how a routine well being checkup entails analyzing varied facets of bodily well-being.
Our method goes past security metrics alone. Good driving habits issues, too — driving respectfully round different highway customers in dependable, predictable methods, not inflicting pointless site visitors or confusion. We’re working onerous to constantly enhance our driving habits throughout the board.
By means of these research, our aim is to offer the most recent outcomes on our security efficiency to most of the people, improve transparency within the AV business, and allow the neighborhood of researchers, regulators, and teachers finding out AV security to advance the sphere.
