Gomentum Station Responds to New AV Research

By the GoMentum Station Team

For over a century, AAA has been an advocate for transportation safety. In keeping with this mission, AAA Northern California operates GoMentum Station, the nation’s largest dedicated automated vehicle testing facility in the US.

GoMentum Station has engaged in and provided perspective on Automated Driving Systems (ADS) safety research since 2019. Today, Waymo released new ADS research where they reconstructed real-world accidents in simulation and tested their technology in these scenarios. GoMentum Station supports data sharing, which enables the industry to improve vehicle safety collectively. 

AAA Northern California, via GoMentum Station, regularly engages in safety research for ADS, including collaborations with leading industry and academic partners. In March 2019, GoMentum Station organized its first workshop on AV safety metrics. The workshop urged the necessity for an enhanced transparency process of ADS safety evaluation, data sharing for safety research, and additional standardized safety assessments, including safety metrics. GoMentum Station has pursued engagements in each of these.

Therefore, GoMentum Station would like to highlight the following points from this research:

  • Waymo’s reconstruction of high-severity collisions from the real-world to simulation is highly relevant and impactful for ADS development. GoMentum Station’s research in novel safety metrics for collision avoidance, formal validation methodologies for ADS underscore the importance of the latest safety metrics and methodologies, as well as the correlation of simulation with real-world testing. 
  • A combination of testing modes is needed to assess ADS safety. Waymo uses three testing methods, including simulation, closed-track testing, and public testing to develop their technology. GoMentum’s collaboration with the University of Waterloo, presented at the SAE World Congress in 2020, aligns with this approach.
  • Sharing safety scenarios and testing results across the industry is critical for validating ADS. GoMentum Station is engaged in a collaborative effort to safely deploy AV using a data-driven policy framework via the World Economic Forum’s Safe Drive Initiative. To continue our pursuit of safer autonomous vehicles, we welcome collaboration and information sharing across the industry, including Waymo.

GoMentum is the nation’s largest dedicated connected and automated vehicle testing facility in the US, located 65 miles from Silicon Valley. Owned and operated by AAA Northern California, the proving ground has over 20 miles of roads and highways set in 2,100 acres. Vehicle technology tested, including ADAS features in partnership with AAA National, at GoMentum Station will redefine the next generation of transportation, bring unprecedented mobility options to people, and advance traffic safety towards zero fatalities.

Accelerating ADAS and AV Development with the GoMentum Digital Twin

Side-by-side of real world and virtual

GoMentum Station and Metamoto announce a new digital twin simulator to accelerate the development and testing of ADAS features and automated driving systems

Authored by Paul Wells

Applying autonomy to safety critical applications — most notably, autonomous vehicles — requires extensive verification and validation. The majority of this testing takes place in scalable simulation tools whereas much of validation and verification is still accomplished in the physical world. As such, correlation between these test modes remains an important consideration when evaluating and advancing the overall efficiency of test efforts.

Metamoto and GoMentum Station are excited to partner to offer the GoMentum Bunker City scene within Metamoto’s massively scalable, cloud-based simulator to help promote this connectivity. Using the GoMentum scene, developers are able to both drive efficiency and go deeper into specific validation subdomains. Contact us for more information about the digital twin.


Physical testing is notoriously resource intensive. To help drive costs down, developers and test engineers are faced with two key options: perform as much virtual testing as possible, and identify the smallest, but still significant, set of physical tests required to produce meaningful assurance and test results. Simulation, when integrated with physical test environments, is an incredibly powerful ally in both of these efforts.


Virtual bunkers

In addition to supporting the overall development and advancement of an autonomous stack, virtual testing within a digital twin environment effectively allows for a faster and more efficient bug discovery process before deploying hardware and drivers into a physical environment. This reduces the likelihood of time-consuming troubleshooting that pops up during the precious time spent either on a track or on public roads. GoMentum, for example, is an unusual environment. The use of the Metamoto scene and simulator allows for virtual exploration of the environment such that static objects in the environment, like bunkers and tall grasses, and dynamic agents, such as cows, turkeys and the like, do not disrupt time spent on the track. Turnaround times thereby become faster, and the cycle between virtual and physical testing continues efficiently.

Parity Testing

An added benefit of leveraging digital twins is the potential for parity into the conformance of virtual and physical test results. Due to the increasing importance of, and reliance on, simulation testing, understanding the relationship between virtual and physical test results is critical. This exploration of parity testing allows for greater awareness of the relationship between sample use cases and model fidelities leveraged in simulation. While the goal of this awareness is principally safety, it also has the potential to drive even greater use of simulation tools.

As part of the new GoMentum Bunker City Digital Twin, GoMentum and Metamoto invite industry and academic participants to partake in research projects covering feature development, parity testing, safety testing, and more.
