ABSTRACT
Perceptual countermeasures to speeding are paint and/or gravel road markings aiming to reduce speed related accidents by influencing speed perception. Some relevant speed perception problems, and theoretical rationale and past research concerning perceptual countermeasures are outlined. The first stage of a detailed research program to be conducted on a modern driving simulator is described. This is a simulator validation study, aimed at verifying the simulator as an appropriate tool for the development and evaluation of perceptual countermeasures. It involved comparing the performance of the simulator with that of an instrumented vehicle in relation to roads with and without transverse rumble lines. Speed outcomes showed that the simulator is indeed representative of what occurs on a real road, and that rumble lines do lead to decreased speed, starting from before the rumble lines are arrived at.
