Characterization of hurried driving based on collision risk and attentional allocation

This paper proposes a method to characterize hurried driving from the viewpoint of attention allocation. When overtaking another car, drivers need to manage the collision risk by allocating their attention appropriately, thus increasing their mental workload. However, drivers´ hurrying mental status likely arises in such situations, even though it is risky. Therefore, this study investigates the relationship between the risk of collision with surrounding vehicles and attention allocation when overtaking other vehicles. We will show that hurried driving can be characterized by outliers from the modeled distribution of normal driving in terms of the relationship between collision risk with the lead vehicle and continuous gaze time to the rear vehicle. Furthermore, a potential method to detect hurried driving is proposed by applying the results.
