Driver eye movements at intersections: a modified flicker method approach
MetadataShow full item record
AbstractInexperienced drivers are involved disproportionately in traffic accidents. Lacking appropriate hazard and decision skills may predispose these individuals to higher crash risks. To understand inexperienced and experienced driver visual behaviour for hazard detection at intersections, twelve less experienced drivers aged 18 to 19 and twelve experienced drivers aged 35 to 48 were shown 36 complex intersection images using a modified flicker method. Twenty-four intersections contained a changing object that was either a pedestrian, vehicle, or a traffic control device. The remaining 12 intersections did not contain a changing object. Visual search was monitored using an eye movement system. Areas of interest were constructed for each image in order to measure visual search behaviour. Less experienced drivers were inclined to fixate on other vehicles within the intersections, compared to experienced drivers who fixated on lights and signs. Time to view the images influenced both tum and object decision accuracy. The less experienced drivers outperformed the experienced group with respect to object detection accuracy. Overall, time to view the intersection, hazard type, and other objects influence driver's visual behaviour and decision making at intersections.
