ISO/TC 22/SC 33/WG 9 - Test scenarios of automated driving systems

This document defines an approach for the categorization of scenarios by providing tags that carry information about the scenarios. This document is applicable to SAE level 3 to SAE level 5 Automated Driving System (ADS)[19].

This document specifies the requirements for the hierarchical taxonomy for specifying operating conditions which enable the definition of an operational design domain (ODD) of an automated driving system (ADS). This document also specifies requirements for the definition format of an ODD using the taxonomy. The ODD comprises specific conditions (which include the static and dynamic attributes) within which an ADS is designed to function. This document is mainly applicable to level 3 and level 4 ADS. An ODD for level 5 ADS is unlimited (i.e. operation is possible everywhere). This document can be used by organizations taking part in developing safety cases for automated vehicles, in particular, for organizations conducting trials, testing and commercial deployment. This document can also be used by manufacturers of level 3/4 ADS to define the ADS’ operating capability. It may also be of interest to insurers, regulators, service providers, national, local and regional governments to enable them to understand possible ADS deployments and capabilities. This document does not cover the basic test procedures for attributes of the ODD. It does not cover the monitoring requirements of the ODD attributes.

This document provides guidance for a scenario-based safety evaluation framework for automated driving systems (ADSs). The framework elaborates a scenario-based safety evaluation process that is applied during product development. The guidance for the framework is intended to be applied to ADS defined in ISO/SAE PAS 22736 and to vehicle categories 1 and 2 according to Reference [10]. This scenario-based safety evaluation framework for ADS is applicable for limited access highways. This document does not address safety-related issues involving misuse, human machine interface and cybersecurity. This document does not address non-safety related issues involving comfort, energy efficiency or traffic flow efficiency.

The document defines terms in the context of test scenarios for automated driving systems (ADS). The document is applicable to ADS of Level 3 and above defined in ISO/SAE PAS 22736.
