Analysis on Relation between the Unsafe Driving Behavior in Actual Environment and the Cognitive Characteristics of Elderly Drivers

Abstract

Traffic accidents involving elderly drivers are major concerns in Japan. Age-related decline in cognitive function is said to be one of the causes of these accidents, so it is important to propose driving support system considering cognitive ability to reduce these accidents. It is necessary to clarify the relation between cognitive ability and driving behavior of elderly drivers. We measured cognitive characteristics of elderly drivers and proposed a method to classify elderly drivers based on cognitive characteristics and examined the relation between cognitive ability and unsafe driving behavior.
