Sustainable Traffic Safety Management at Accident Black Spots Combined with Drivers’ Psychology and Vehicle Engineering Using Eye Mark Recorder☆

Abstract This paper proposes an integrated approach for sustainable traffic safety management at accident blackspots, including a mechanism that tracks the occurrence of accidents from the moment of drivers’ vision to actual accident occurrence, via vehicle behavior. An accident black spot can become a “vicious circle” of accident occurrence and safety countermeasures, where a safety countermeasure is repeatedly performed, but its effect soon fades each time. For such a spot, implementation of a safety countermeasure from only the highway point of view has no sustainability. Therefore, to be effective as one of the next-generation safety countermeasures, the method must integrate considerations from traffic engineering, drivers’ psychology, and vehicle behavior. This paper proposes and discusses a next-generation, integrated traffic safety management method and an explanation of a mechanism that tracks accident occurrence where drivers watch first and then how vehicles behave and lastly what accident risk increases as the series of event.
