The second part of ISO 21934, titled "Prospective Safety Performance Assessment of Pre-Crash Technology by Virtual Simulation - Guidelines and Requirements for Application" has been published.

The International Organization for Standardization (ISO) has published a new Technical Specification, ISO/TS 21934-2:2024, titled "Road vehicles - Prospective safety performance assessment of pre-crash technology by virtual simulation, Part 2: Guidelines and requirements for application." This document is a significant step forward in harmonizing safety performance assessments of pre-crash technologies in road vehicles.

Why is this Technical Specification important?

Safety performance assessment is crucial for developing effective safety technologies and proving their efficacy. Traditionally, retrospective analyses have required extensive crash data, a process that can take years to yield meaningful results. Early inquiries by the P.E.A.R.S. Consortium revealed a lack of standardized approaches in prospective safety performance assessments.
This new technical specification (TS) addresses this gap by providing detailed guidelines and requirements for conducting prospective assessments via virtual simulation, ensuring that results are comparable across different studies and tools.

Who benefits from this document?

This TS is relevant for anyone involved in the assessment of in-vehicle safety technologies, particularly those who use simulation methods for prospective evaluations. It provides a standardized approach that will be invaluable to automotive safety engineers, researchers, and regulatory bodies.

How will it be used?

ISO/TS 21934-2:2024 outlines specific methods and guidelines for the prospective safety performance assessment of pre-crash technologies. By defining a common framework for these simulations, it helps ensure consistency and reliability in the assessment results. This harmonization is essential for comparing the effectiveness of various safety technologies and supporting their development and regulatory approval.

Who made it happen?

This TS was developed by Working Group 7 (WG7) “Traffic accident analysis methodology” under ISO/TC 22/SC 36 “Safety and impact testing.” Major contributions to the TS came from the P.E.A.R.S. Consortium.

Integration with V4SAFETY project (Horizon Europe)

V4SAFETY partners contributed to this TS through P.E.A.R.S. The content of the TS, such as the baseline approaches (A, B, C1, C2), is further developed in V4SAFETY, introducing baseline approaches like A0P, B0P, B2P, and others. V4SAFETY focuses on applying these guidelines to enhance in-vehicle safety technologies that act prior to a collision, as well as extending to other technologies related to infrastructure and in-crash scenarios.
