A Multi-Level Framework for Traffic Safety Assessment under Automated Driving Functionalities: the Need and Outline of a Holistic Approach

Abstract

The rapid introduction of automated driving functionalities in vehicles, has forced the necessity to systematically organize the methodologies for traffic safety assessment. Their safety impacts depend on many factors: human, vehicle, traffic, size of implementation. Modelling and simulations on the driver up to the societal level, play a vital role in assessment. This paper discusses the need, as well as an approach, to develop a multi-level safety assessment framework, facilitating the mitigation of risks. Via a research-driven format, this paper provides practitioners with a strategy to effectively perform safety assessment, offering practical, stepwise guidelines regarding the relevant models and tools.
