Researchers have developed SevDiff, a novel diffusion model designed to generate realistic long-tail conflict trajectories for Advanced Driver-Assistance Systems (ADAS) evaluation. Unlike previous methods, SevDiff can be conditioned on a specific Time-to-Collision (TTC) value, ensuring generated scenarios match the requested severity. The model demonstrates high accuracy in generating conflict trajectories within specified TTC ranges, with physically plausible kinematic features and a clear, interpretable degradation pattern as the requested TTC increases.

IMPACT Enhances ADAS testing by enabling generation of rare, critical conflict scenarios, potentially improving safety system robustness.
