Visual Strategies Used for Time-to-Arrival Judgments in Driving

This article reports on a study undertaken to investigate the sources of visual information that are involved in the anticipation of collisions. The authors recorded eye movements while participants made relative timing judgments about approaching vehicles at a junction, in a virtual driving environment. The authors note that the avoidance of collisions is a critical aspect in driving, particularly where cars enter a line of traffic from a side road. The study included two experiments: the effects of the angle of approach of the vehicle and the type of path (straight or curved) of the observer; and the speed of both the observer and the approaching car. Eye-movement analysis showed that visual strategies in relative timing judgments are characterized by saccadic eye movements back and forth between the approaching car and the road ahead, particularly the side line which may serve as a spatial reference point. The results suggest that observers use the distance of the car from this reference point for the visual strategies used for relative timing judgments.
