DIN SAE SPEC 91518:2026-01

This document defines terms and requirements for the consistent, multi-application acquisition and storage of spatiotemporal data of ground-based traffic scenarios as a metadata standard. This document defines terms for measured attributes and derived attributes, for example with respect to scenarios, vehicle interior and passenger states, acquisition conditions, traffic situation, including: for each such attribute: information about units of measurement and value ranges; for each such attribute: information about data quality by stochastic uncertainty models; for each such attribute: information about measurement, processing or annotation principles; for each such attribute, if applicable: information about temporal and contextual referencing with other attributes or external data; for each such attribute, if applicable: references to or harmonization with literature or existing standards in the field; for each such attribute, if applicable: information on compatibility with or methods of conversion towards established interfaces, for example for simulations or existing external data format standards. This document is applicable to spatiotemporal data of individual traffic participants both from real-world data acquisition and from simulations for motorized and non-motorized road traffic, pedestrian traffic, rail traffic, or a combination of these.
