Abstract

<p>This paper proposes a caution system for the following two purposes: (1) inferring driver intentions to change lanes, and (2) issuing caution messages when the driver seems distracted. The idea of our method is that, when the driver is not distracted, driver intent to change lanes can be found via analyzing driver eye movement based on a model of driver behavior to check the side-view mirror for preparation of a lane change. If, on the other hand, the driver is distracted, the system fails to detect the intent even when the traffic environment suggests that the driver may want to change lanes. The results of a cognitive experiment showed that a caution system is effective to prevent the deterioration of the checking behaviors and to relieve the risk of a collision to the slow lead vehicle at the initiations of changing lanes. </p>
