  For future application of automated vehicles in public traffic, ensuring
functional safety is essential. In this context, a hazard analysis and risk
assessment is an important input for designing functionally vehicle automation

assessment (HARA) according to the ISO 26262 standard for a specific Level 4
application, namely an unmanned protective vehicle operated without human
supervision for motorway hard shoulder roadworks.
