Abstract

Older driver death in traffic is about 40% of all deaths and increasing sharply from year to year. The purpose of this research is to develop a system to check the driving ability of the elderly with comprehensive measurement of visual, cognitive and performance necessary for safe driving. The method and prototype-system for measuring the driving ability (especially cognitive and decision performance) of the elderly were created. In this system, field of view, static visual acuity for under low contrast and glare environment, cognitive and decision performance to three levels of difficulty (magnitude of driver workload) were measured. In sample measurements of visual performances, among the elderly, the detection rate was notably lower with driving operations (useful field of view) than without (static field of view), indicating a marked reduction in field of view when driving.
