Outline of Final Research Achievements

Japan, where the aging rate exceeds 28%, has been the fastest aging country in the world. The measures to prevent dangerous driving of elderly drivers become an urgent issue, so that the driving characteristics of drivers must be further taken into consideration. Targeting Brain Dock patients, three types of dangerous driving behaviors (illegal, irritable, aggressive) were classified and indicated brain features of regional gray matter volumes in each. Furthermore, the aging brain was defined as the grading of white matter lesions and the degree of brain atrophy, and the elderly drover’s operational performance of actual vehicles decreased according to the aging brain. Thus, MRI may enable to identify a dangerous driver in the elderly. In addition, a head-mounted display (HMD) presented 3D imaging of dangerous driving scenes. However, the measures for 3D imaging sickness is indispensable for the prevention from traffic accidents under automated driving system.
