Inspection of the relationship between the car speed and the visually recognizable distance of the person lying on the road in night driving

Abstract

 In Accidents that the car collided with the person lying on the road, the case fatality rate and hit-and-run rate were high, so the recognition of the location where the victim could be found was often the issue. There was also the cognitive error due to the driver’s belief that a person could not lie on the road. There were many researches on the driver’s visibility in pedestrian accidents, whereas there were few studies conducted on those of the person lying on the road. In this research, we conducted the driving experiment to examine whether the visually recognizable distance of the person lying on the road in night driving changed depending on the speed. There were no significant difference of the visually recognizable distance between slow speed, 40 km/h, and 60 km/h.
