Perceptual countermeasures (PCMs) are non obtrusive, low cost road-markings, usually involving only paint or/and gravel. They aim to slow vehicles down by changing a driver's perception of what is an appropriate travel speed. Examples are painted transverse lines, transverse painted rumble lines, center-line widening via paint, and gravel or painted strips on the outer edge of the road. A few countries have used perceptual countermeasures, although there has traditionally been very little in the way of scientifically sound evaluations of them, both for the short and long term. The objective of the current project, sponsored by the Federal Office of Road Safety of Australia and the Roads & Traffic Authority of the State of New South Wales (Australia), is to systematically investigate and evaluate the effectiveness of all existing, as well as newly developed perceptual treatments.
