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.
Abstract
Overview
ISO 34503:2023 - "Road Vehicles - Test scenarios for automated driving systems - Specification for operational design domain" - defines a hierarchical taxonomy and a definition format for the Operational Design Domain (ODD) of automated driving systems (ADS). The ODD captures the specific static and dynamic conditions within which an ADS is designed to operate. ISO 34503:2023 is primarily aimed at level 3 and level 4 ADS (level 5 is considered unlimited) and supports consistent, machine- and human-readable ODD definitions to enable safe testing, trials and commercial deployment.
Key topics and requirements
- Hierarchical ODD taxonomy: structured classification of operating conditions to describe location, road types, drivable area, junctions, scenery elements, and zones.
- ODD attributes: inclusion of both static (infrastructure, signage, road geometry) and dynamic (weather, illumination, traffic agents, connectivity) attributes.
- Definition format requirements: specifies human readability, inclusion/exclusion/conditional expressions, extensibility, relationships between attributes, objective boundaries, and statement composition.
- Scenery and environmental elements: covers drivable area types, lane specification, junctions (roundabouts/intersections), temporary structures, weather, particulates, illumination and connectivity.
- Dynamic elements & agents: treatment of subject vehicle, traffic agents and their role in scenario creation.
- Implications for scenario-based testing: taxonomy enables efficient scenario creation, parametrization and linking of ODD to test scenarios.
- Scope limits: the standard does not define basic test procedures for ODD attributes or monitoring requirements for ODD attributes.
Applications and users
ISO 34503:2023 is practical for organizations involved in ADS safety, testing and deployment:
- ADS manufacturers and suppliers - define and communicate operating capability for level 3/4 systems.
- Test and trial operators - create consistent, repeatable scenario sets and parametrized test conditions.
- Safety case developers and verification teams - assemble evidence tied to explicit ODD boundaries.
- Regulators, insurers and public authorities - assess deployments, procurements and regional suitability of ADS services.
- Service providers and integrators - plan operations and define service-area limitations based on ODD attributes.
By standardizing ODD taxonomy and definition formats, ISO 34503 helps improve ADS safety communication, supports scenario-based verification and enables clearer regulatory and commercial decision-making.
