Effect of Adaptive Caution on Driver's Lane-Change Behavior under Cognitively Distracted Condition

摘要

This paper investigates caution type message that is given to a driver in two ways. One refers to driver's characteristic of intentional eye movement for changing lanes, and the other is adaptive to driver state as well as the characteristic. Experimental results imply the two ways' effectiveness of improving the intentional checking behavior that might be degraded by a cognitively distracted secondary task. Meanwhile, this study also indicates that the later way is more effective for improving a maneuver of changing lanes. It is suggested that it would be more acceptable to consider driver state into a support system.
