Effect on hasty state for driver´s visual perception

Driver´s hasty state is one of major psychosomatic states which may result in traffic accidents. This paper describes an effect on hasty state as to driver´s perception by means of detecting the change of driver´s useful view of field and time to perception of a moving object. Hasty state was reproduced by means of using a scenario of traffic incidents in rush operation on a driving simulator basis. A stereo camera based tracking unit was used for measurement of movement of driver´s eyes and head while driving ahead in traffic incidents occurring situation. It was clarified that driver´s useful field of view had decreasing tendency, meanwhile time to percept to the moving object was prolonged when subjects operated rush driving to a destination. Finally we propose a concept to provide information on psychosomatic states to a driver was in order to lower a potential risk to be involved in a traffic accident.
