Study for the effect of hasty state while driving on potential risks

Driver´s hasty state is one of psychosomatic states which may result in traffic accidents. This paper describes analytical effects on hasty state for driver´s perception by means of detecting the change of driver´s useful view of field and time to perception of moving objects. Then we proposed a concept of a function for detecting driver´s hasty states for an intelligent driving support system. The function may become one of the content of the next generation Vehicle - Infrastructure cooperative safety system by means of using ultra high speed communication technology in the next stage.
