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

摘要

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.
