ARRB Transport Research, in conjunction with the Monash University Accident Research Centre (MUARC), trialled two perceptual countermeasure treatments for the Australian Transport Safety Bureau (ATSB) in association with the Roads and Traffic Authority of NSW and VicRoads. The trials marked the final of a four phase project investigating perceptual countermeasure treatments and their applicability in Australia. Based on the findings of a comprehensive literature review and simulation studies, two perceptual countermeasure treatments were selected for trial. The first treatment consisted of enhanced lateral guide post spacing with ascending heights around a curve. The second treatment is a peripheral transverse line (occurring on the edges but not in the centre of the travelling lane), placed at regular intervals over 400m on the approach to an intersection. The present paper outlines the key findings of the first three stages of the study, and reports the results of the trials of the two perceptual countermeasure treatments.
