As automated vehicles are expected to significantly reduce the number of fatalities in road traffic, ensuring their safety is one of the most critical challenges in the industry today. The Responsibility-Sensitive Safety (RSS) concept is a step towards this goal. RSS formalizes reasonable boundaries for the foreseeable worst-case behavior of traffic participants by defining clear mathematically proven rules. All parameters used in RSS have a physical meaning and are thus well understandable, but the values of these parameters have a crucial effect on the applicability of this approach. Choosing too conservative parameter values may impact traffic flow, while the opposite could lead to uncomfortable or potentially unsafe driving behavior. While a majority of work concentrated on the longitudinal use case, in this work we focus on finding reasonable parameter values for lateral safety. We propose scopes and parameter …
