Research on the experimental road signs perception time and their intelligibility

Abstract

Eye tracking technology is often used in road safety research. Eye tracker are used during real and simulated driving to investigate driver’s behaviour. It is also used for assessing influence of new elements, like experimental road signs or road signs from different country, on driver’s behaviour and performance. However it should be noted that, the probability that the signs will be noticed cannot be solely assessed by eye tracking data. Therefore there is a need to complete the results with additional sources of data, eg questionnaire study. In the paper results of research concerning road signs perception carried out with 33 volunteers are presented. Twelve boards with different road situations in the form of photos taken from the driver's perspective were prepared. After the exposure, the volunteer answered questions about the memorized information presented on the road signs.
