On-demand Scenario Generation for Testing Automated Driving Systems

Location: Junior Stage

Valuating the decision-making system is indispensable in developing autonomous vehicles, while realistic and challenging safety-critical test scenarios play a crucial role. Obtaining these scenarios is non-trivial due to the long-tailed distribution, sparsity, and rarity in real-world data sets. To tackle this problem, we introduce a natural adversarial scenario generation solution using naturalistic human driving priors and reinforcement learning. Our experiments on public data sets demonstrate that our proposed model can generate realistic safety critical test scenarios covering both naturalness and adversariality with 44% efficiency gain over the baseline model.
