Abstract [en]

It is easy to agree that an automated driving system shall be safe, but it is an on-going discussion what safe means. Several Risk Acceptance Criteria (RAC) candidates have been suggested, but a closer analysis indicates that not all of them are related to risk in a traffic safety sense and that perhaps they are better described as properties that an ADS should be designed to exhibit for other reasons.This paper discusses safety aspects of Automated Driving System (ADS) features and the different incentives and arguments that drive the design of an ADS. More precisely, this paper explores different design goals for safe automated driving and puts forward a combination of Risk Acceptance Criteria (RAC) for limiting the risk of harm. These criteria are motivated and contextualized using a simple real-world traffic example. Furthermore, it is also shown why run-time risk transfer is unavoidable in any system that makes tactical decisions under uncertainty and why this motivates avoiding thought-examples such as the trolley problem as basis for ADS design.
