DIN DKE SPEC 99004:2025-05

This document defines a taxonomy for the Operational Design Domain (ODD) for fully automated rail vehicles (automated driving systems in rail), which is also based on the description of other domains (for example, automotive). This document shows the extent to which common concepts or parts of the taxonomy description can be modularized or made reusable. It covers important operating conditions for railway-specific AI applications such as Automatic Train Operation (ATO), for example environmental or track conditions. This document creates the basis for describing operating conditions (OC) of AI-based railroad applications such as automated driving systems in a standardized and sufficient manner. However, this document does not provide specific information on concrete ODD descriptions for individual routes and the assessment of such an ODD system. This document does not specify requirements for an ODD necessary for safety functions and health protection, such as for the detection of persons in a hazardous area. This also applies to so-called assistance systems. This document is not to be used for general automated systems. This document is intended for users, manufacturers, operators, testers and developers in the described field. This DIN DKE SPEC has been developed according to the PAS procedure. The development of a DIN DKE SPEC according to the PAS procedure is carried out in DIN-DKE-SPEC-consortiums and does not require the participation of all stakeholders.
