Testing autonomous vehicles (AVs) in potential near-accident scenarios is critical for evaluating safety, but is difficult and unsafe to do in the real world. In this episode of DRIVE Labs, we discuss a new method from NVIDIA researchers called STRIVE (Stress-Test Drive), which automatically generates potential accident scenarios in simulation for AVs. The key to STRIVE is a generative AI model of traffic trajectories that encourages scenarios to be realistic even when they contain a potential accident. STRIVE produces diverse and plausible potential accident scenarios based on real-world data, allowing us to safely evaluate the planning part of the AV stack at scale in simulation.
