IMPORTANT DRIVER PERFORMANCE ON RURAL CURVES THROUGH PERCEPTUAL CHANGES-PHASE III
The research design, road user results and test driver results are outlined of the third phase of a study in which three Delaware county rural curves were modified with alterations in pavement markings. The modifications involved introduction of transverse striping, accenting the inside perspective angle, and the use of the Wundt illusion. It was found that driver speed profiles on rural curves can be affected by novel pavement markings designed to provide specific perceptural effects. High speeds were most susceptible to change due to the modifications. Speed reductions were not found 30 days later. Intervehicular speed variability was also found to be reduced. The most effective modification was the accent on the inside edge marker. In comparison special signs had little effect, Painted markings are therefore recommended for the remedy of high accident curve sites.
