To assess older drivers, naturalistic driving data was analyzed to examine the link between traffic conditions and safety confirmation. High-risk drivers showed notable confirmation deficits at obstructed stop intersections without vehicles.

This study aims to establish a comprehensive driving performance evaluation index by examining the correlations between diverse human capabilities, such as essential physical and cognitive functions, and accident propensity. Our proposed methodology involves measuring and analyzing dynamic grip strength, which fluctuates over time, to assess these multifaceted functions. This innovative approach holds promise for simultaneously gauging multiple performance indicators using only dynamic grip strength measurements.

This study investigated the associations between elderly drivers’ motivations for life safety, health improvement, and safe driving, and the outcomes of online driving aptitude assessments, their engagement in educational programs for safe driving and health promotion, as well as their evaluations of these programs.

Older drivers tend to overestimate their own driving abilities. This study experimentally examined the effectiveness of educational interventions designed to correct such overestimation, focusing on changes in their awareness of safe driving. The results revealed that the presence and extent of overestimation correction increased their awareness of age-related decline and burden associated with driving. These changes in awareness were also reflected in subsequent modifications in their driving behavior.

Verification of the Usefulness of a Vehicle Behavior-based Cognitive Decline Detection Technology under Unrestricted Driving Conditions

Yoshito Ogawa･Tatsuya Obuchi (Toyota Motor)

This study reports on the usefulness of a vehicle behavior-based cognitive decline detection technology under unrestricted driving conditions. Currently, a technology has been proposed that detects cognitive decline in drivers using vehicle behavior. In this study, the usefulness of this technology under unrestricted conditions was evaluated with vehicle behavior from the daily driving of older drivers. The results suggested the potential to detect cognitive decline.
