Outline of Final Research Achievements

The information providing and warning of road traffic status were mainly done by the visual information such as road sign so far. But, it is in sufficient in the case of wrong way driving especially for aged drivers. Therefore it is desired to develop new dissemination methods besides the sight from the infrastructure base. This research considers the method not only visible but also audible and haptic methods. We adopted the dynamic pictogram for visible, parametric speaker for audible and dynamic hump for haptic method and evaluated each other. For drivers we took MRI data by measuring the Leukoaraiosis and Cerebral shrinkage degree. By the questionnaires to aged drivers we found that 3 out of 4 aged drivers do not use or see curve mirrors while driving and so we developed new intelligent curve mirror system.
