Summary
This position paper addresses the limitations of using Situation Awareness (SA) as a relative metric in driving safety research and explores the feasibility of establishing a normative interpretation to define "safe" versus "unsafe" driving. Currently, SA measures are predominantly used to compare performance across experimental conditions, such as the impact of distractions or interfaces, rather than to determine if a driver’s awareness level meets a safety threshold. The authors argue that this relative approach prevents researchers from assessing absolute safety, motivating an investigation into whether a normative criterion for SA can be established. The study employed semi-structured interviews with five experts in the field of Situation Awareness, selected based on their publication history and expertise in task analysis and SA measurement techniques like SAGAT. Prior to the interviews, experts completed a preparatory survey identifying SA requirements in specific traffic scenarios. The interviews focused on the theoretical relationship between SA and safe driving, the practical challenges of defining safety criteria, and methodological approaches for selecting and weighting SA requirements. The researchers analyzed the transcripts to identify recurring themes, consensus, and disagreements regarding the operationalization of SA for safety assessment. The findings indicate a strong consensus that SA is a prerequisite for safe driving and correlates positively with safety performance, though the relationship is probabilistic rather than deterministic. Experts agreed that high SA reduces the likelihood of accidents but does not guarantee safety due to external factors or decision-making errors. Consequently, establishing a fixed normative threshold for "safe" SA was deemed theoretically inappropriate and practically difficult, as the criticality of specific information varies dynamically with context and driver goals. Experts highlighted that SA requirements shift in importance based on the scenario (e.g., hazardous vs. critical) and that a single combined SA score obscures important trade-offs in attention. Instead, they advocated for analyzing SA per query or level to capture these nuances. The paper concludes that while a rigid normative cutoff for SA is unfeasible, a weighted, criterion-based approach could enhance the utility of SA measures. This involves identifying common, safety-relevant SA requirements through Goal-Directed Task Analysis and weighting them based on their contextual importance and impact on safety outcomes. The authors suggest that future research should focus on resolving methodological inconsistencies in scenario selection, requirement relevance, and scoring to better understand the probabilistic link between SA and driving safety. This structured approach aims to improve the diagnostic value of SA measures for assessing driver performance and safety.
Key finding
Experts concluded that while situation awareness is fundamentally linked to driving safety, establishing a definitive normative criterion is challenging due to the probabilistic nature of the relationship and the context-dependent importance of specific awareness requirements.
