Eye behaviour as a hazard perception measure

Hazard perception during driving is essential in detecting and avoiding traffic incidents. In this study, eye movement analysis is used to measure the driver's hazard perception while engaged in different traffic scenarios on Australian roads. Participants were asked to observe recordings of four different traffic scenarios and react to hazards by clicking the mouse. The aim of this study is to examine three hypotheses; (1) the relationship between driver's experience and hazard identification, (2) the use of pupil dilation as a measure of hazard perception, and (3) the ability of gaze fixation points to determine the driver's perception of the hazard. The results show that eye movement dynamics and change in pupil diameter can provide good measures of the drivers' hazard perception and prediction.
