Metadata in the description of road scenarios for testing autonomous vehicles

Abstract

<ns3:p>The article presents results of an analysis of metadata structures used to describe test scenarios for automated vehicles in selected research initiatives and international standards. The paper examines approaches used in projects such as SYNERGIES, PEGASUS, and CETRAN, ISO 21448 (SOTIF) and OpenSCENARIO standards, as well as in the regulatory documents such as Highway Capacity Manual (HCM) 2000 and the NHTSA Standing General Order on Crash Reporting. The comparison reveals common metadata elements, such as descriptions of weather conditions, road infrastructure characteristics, road users, and event dynamics, which form the basis for modelling test scenarios. At the same time, significant differences resulting from different objectives—from technical validation and simulation to reporting on real-world events—are identified. The SYNERGIES project stands out with its focus on data quality, interoperability, and traceability mechanisms, making it a key step towards harmonizing the European scenario data ecosystem. The analysis results confirm the need to develop an integrated metadata model that will enable the consistent use of scenarios in the research, testing, and certification processes of automated vehicles.</ns3:p>
