Hazard Analysis and Risk Assessment for an Automated Unmanned Protective Vehicle
This work addresses safety concerns for automated vehicles in public traffic, specifically for Level 4 applications in roadwork scenarios, but appears incremental as it applies an existing standard to a new use case.
The paper tackled the problem of ensuring functional safety for an automated unmanned protective vehicle used in motorway hard shoulder roadworks by conducting a hazard analysis and risk assessment (HARA) according to the ISO 26262 standard, with no specific results or numbers reported.
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 systems. In this contribution, we present a detailed hazard analysis and risk 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.
