Predicting older driver on-road performance by means of the useful field of view and trail making test part B

This study compared two measures of divided attention, the Useful Field of View (UFOV) and Trail Making Test Part B (Trails B), in order to determine which could more accurately predict the on-road outcomes of drivers. The article focuses on older drivers, for whom medical conditions can compromise visual-cognitive functions, among which is divided attention, which is the ability to construct information from multiple sources in order to perform tasks. Receiver operating characteristic curves for both significantly predicted outcomes. When contrasting Trails B and UFOV, the only significant difference was found in the Risk Index (RI), which indicated that UFOV was a better predictor, though the accuracy of Trails B was deemed acceptable.
