Building high-quality scenarios for ADAS and AD testing requires a deep understanding of the nuances of test scenario creation. Engineers can spend hours creating a realistic and well-designed logical scenario, and then spend additional time ensuring the test criteria are fully aligned with system-level and module-level requirements. Overall, scenario sets should provide comprehensive test coverage over an operational design domain (ODD), requiring a thoughtful and accurate taxonomy to categorize and formalize the ODD. As regulators may only provide light guidance, teams need sets of standard test scenarios to accurately assess regulatory compliance.
