Abstract:


Suppression of vehicle speed is very important for decreasing fatal accidents caused by speeding violations. The purpose of this study was to reveal the effects of repetitive patterns painted on the road, which creates a moving visual illusion, on the driver’s speed perception. First, we investigated the moving illusion effect of repetitive patterns with a brightness gradient in images with pictorial depth cues. Then, we performed an experiment using a computer driving simulator. Results showed that these gradient patterns on the road led observers’ to overestimate vehicle speed by 13–19% compared to a road without patterns.
