Effects of hazard types on drivers’ risk rating and hazard response in a video-based hazard perception task

Video-based road commentary training improves hazard perception of young drivers in a dual task.

This study used a video-based hazard perception dual task to compare the hazard perception skills of young drivers with middle aged, more experienced drivers and to determine if these skills can be improved with video-based road commentary training. The primary task required the participants to detect and verbally identify immediate hazard on video-based traffic scenarios while concurrently per...

The effect of simulated cataracts on drivers' hazard perception ability.

PURPOSE We investigated the extent to which simulated cataracts slow a driver's ability to anticipate potential traffic hazards, a skill that has been found to correlate with crash risk. In previous studies, we found a significant correlation between contrast sensitivity and hazard perception in a sample of older drivers. The present study allowed us to determine the causal direction of this re...

Eye fixation scanpaths of younger and older drivers in a hazard perception task.

Our previous research has shown that observing patterns of eye fixations is a successful method of establishing differences in underlying cognitive processes between groups of drivers. Eye movements recorded from drivers in a laboratory while they watch film clips recorded from a driver's perspective can be used to identify scanpaths and search patterns that reveal ability differences. In the p...

Risk, Hazard, and Disaster

Natural hazard research began as a study of cultural perceptions to extreme naturally occurring events. Since the advent of the study, natural hazard literature has become steeped in terminology that is sometimes confusing to the reader. The concepts of hazard, risk, and disaster are often confused with one another and with the extreme event itself. Although the extreme event is inherent in haz...
