With age-related changes in cognitive functioning including attention, older drivers experience increased crash risks and are particularly overrepresented in vehicle crashes in driving situations such as making a left turn and merging with traffic. Effective remedies via assessment, training, and interface design require understanding of individual performance in specific scenarios. In this study, we investigated older driver performance characteristics in eight distinct hazard scenarios. Participants completed a task measuring their attentional processing of information and decision at intersections. The findings revealed sizable heterogeneity in performance across scenarios, with older drivers being more conservative or liberal in certain situations. Some group differences were also observed. These findings suggest the importance of examining individual performance in unique driving scenarios in addition to an aggregated accuracy across all scenarios.
