Operational Design Domain (ODD) attributes define the environmental and infrastructural conditions under which Automated Driving Systems (ADS) can safely operate. These attributes include factors such as road and lighting conditions, as well as infrastructure elements like lane markings and road conditions. However, existing ODD definitions are often ambiguous and lack specificity, making it challenging to validate their presence in datasets. The absence of precise ODD definitions and robust validation mechanisms poses significant challenges, as it remains unclear whether ADS training and testing datasets adequately represent real-world operating conditions. This gap introduces risks that could compromise the safe deployment of ADS in diverse environments. To address this issue, we introduce FODSE (Framing ODDs as Domain Specifications for Evaluation), a semi-automated AI-powered approach that refines ODD attributes into structured, context-aware domain specifications and systematically evaluates their presence in datasets. FODSE leverages Retrieval-Augmented Generation (RAG), multimodal AI, and prompt learning to enhance specification clarity and dataset completeness. Experimental evaluation on two commonly adopted datasets in ADS demonstrates that FODSE significantly improves dataset validation accuracy, achieving up to 96.8% classification accuracy for an extended set of lane marking variants and 97.8% for roadway users—two key ODD attributes. Expert assessments confirm that FODSE effectively reduces ambiguity and enhances contextual adaptability, reinforcing its potential to improve dataset integrity and ensure safer, more reliable ADS training and validation.
