Characteristics of the gaze of a driver following a preceding vehicle and cognition time for an approaching vehicle

摘要

The effect of eye movement on the gaze area was investigated using a driving simulator when a driver simply followed a preceding vehicle on a straight road under two conditions; while focusing on a vehicle and while focusing on a vehicle and red points in a wide area of the front screen. The area of the distribution of the gaze points was greater in the latter case, especially on the right-hand side. The results suggest that a tool that forces a driver to gaze across a wide area would encourage gazing in side areas. The study also investigated the cognition time of a driver as other vehicles suddenly emerged at intersections. The cognition time at the first intersection was significantly longer than that at the last intersection, suggesting that the first event of an approaching car enlarged the area of the driver's vision as the driver displayed greater caution.
