Presentation Description
Assessing the dynamic driving task (DDT) performance in scenario-based testing is an important component of an overall safety case-based approach to ensuring that an automated driving system (ADS)-equipped vehicle (AV) is safe for deployment.
In this presentation, the DDT performance assessment of the May Mobility AV is executed for a series of scenarios. The evaluation uses the DDT assessment (DA) metrics from the recently published SAE J3237 Recommended Practice as well as the DA Methodology for interpretation of multiple metrics measurements developed by the Science Foundation Arizona - Arizona State University research collaboration. Each scenario is assigned a DA Score based on the DDT performance, which provides insight into how well the May Mobility AV under test is able to navigate a given scenario. The complexity and relevance of the scenario, as well as the fidelity of the test method are determined for each scenario test, and these are weighting factors for the DA score. The weighted DA scores can be accumulated and added to the safety case to provide evidence for the deployment argument.
