The differences of eye movement according to turn conditions in driving situation: Comparison of older and younger drivers

This research examined differences of eye movement in left or right turn conditions at each of intersection type between older and younger drivers. To examine these differences, we measured visual scanning time by eye-marker. The results showed that on the type T1 which has the front, the left, or the right roads, older drivers tend to keep eyes on the front for a short time than younger drivers in turning right. On the type T2 which has the left and the right roads, older drivers watched the left for a short time in turning left than younger drivers, while watching the right for a long time in turning right. On the type Cross which has the front, the left, and the right road, older drivers kept eye on the front for a short time in turning right than younger drivers. The results indicate that older drivers could perform more risky driving behavior in turning right at the intersection which has the front road than younger drivers. It also suggested that older drivers could perform more risky driving behavior in turning left at the intersection which has the left and right roads than older drivers, but they could perceive accurately the unexpected driving in right turning situation.
