# Hazard Analysis and Risk Assessment for an Automated Unmanned Protective Vehicle

## TL;DR

This paper presents a detailed hazard analysis and risk assessment for a Level 4 unmanned protective vehicle used in motorway hard shoulder roadworks, emphasizing functional safety for automated vehicles in public traffic.

## Contribution

It provides a comprehensive HARA following ISO 26262 standards specifically for an unmanned Level 4 protective vehicle, a novel application in this context.

## Key findings

- Identification of potential hazards for unmanned protective vehicles
- Risk levels assigned according to ISO 26262 standards
- Guidelines for designing safer automated vehicle systems

## Abstract

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.
