A possible countermeasure for accidents at intersections with good visibility -effect of a road side fence on detection of a vehicle on collision course-

摘要

The present study investigated a possible causative factor of intersection accidents (1st experiment) and a possible countermeasure to prevent them (2nd experiment) from the point of visual search performance. Both experiments were conducted using the advanced driving simulator. In the first experiment, it was shown that the detection of a vehicle on collision course was much more delayed especially when the object was further away in the peripheral visual field. In the 2nd experiment, the effectof road side fences on the detection of a vehicle on collision course was studied. Fences were set along the road side of the other crossing path, they made a vehicle on collision course abruptly appear from behind a fence. It was shown that the detection was earlier with fences compared to the without fences condition.
