#WEST AUSTRALIAN HAZARD PERCEPTION TEST DRIVERS#
Moreover, young drivers are likely to be the first and most aggressive users of new technology. Cell phones, text messaging, MP3 players, and other nomadic devices all present a threat because young drivers may lack the spare attentional capacity for vehicle control and the ability to anticipate and manage hazards. The distraction potential of infotainment technology stresses the same vulnerabilities that already lead young drivers to crash more frequently than other drivers. The rapid evolution of computing, communication, and sensor technology is likely to affect young drivers more than others. Overall we concluded that there was support for the validity of the Hazard Percep- tion Test for all ages but the Hazard Change Detection Task might only be appropriate for use with older drivers.
However for drivers aged 65 and over, test performance declined with age and correlated with both hazard perception and Useful Field of View. For the Hazard Change Detection Task, novices responded quicker than the experienced drivers, contrary to crash risk trends, and test performance did not correlate with measures of overall hazard perception. For drivers aged 65 and over, scores on the Hazard Perception Test declined with age and correlated with both contrast sensitivity and a Useful Field of View measure. For the Hazard Perception Test, young novices were slower than mid-age experienced drivers, con- sistent with differences in crash risk, and test performance correlated with scores in pre-existing Hazard Perception Tests. A Hazard Change Detection Task was developed to measure how quickly drivers can detect a hazard in a static image regardless of whether they consider it hazardous or not. A Hazard Perception Test was developed to measure how quickly drivers could anticipate hazards overall, incorporating detection, trajectory predic- tion, and hazard classification judgements. This paper reports the develop- ment of two measures designed to separate these processes.
Hazard perception in driving involves a number of different processes.
