This paper proposes a method to characterize hurried driving from the viewpoint of attention allocation. In overtaking, drivers need to manage the collision risk by allocating their attention appropriately, thus mental workload of the driver tends to be increased in such situation. However, hurry impulses likely arise in such situations even though it is risky. Therefore, relationship between collision risks between surround vehicles and attention allocation will be investigated in overtaking. It will be shown that hurried driving can be characterized by outlier from the modeled distribution of the normal driving in terms of relationship between the collision risk toward the lead vehicle and the continuous gaze time to the rear-side vehicle. Furthermore, a method to detect hurried driving will be proposed by applying the results.
