Summary
This study investigated how specific roadway design elements influence driver behavior, particularly speed reduction, using a driving simulator. Researchers tested 32 licensed drivers across scenarios varying pavement color, landscape treatments, and lighting poles on a modeled segment of Highway 61 in Tofte, Minnesota. The results indicated that white pavement treatments produced desirable traffic calming effects by encouraging more moderate speeds and greater speed changes. Conversely, the presence of lighting poles did not contribute to traffic calming, and landscape architecture treatments showed inconsistent effects on driver speed choices. The study concluded that visualization tools enhance design communication and recommended implementing white pavement treatments for the target reconstruction project.
Key finding
White pavement treatments produced desirable traffic calming effects by encouraging more moderate speeds and larger speed changes, whereas lighting poles did not contribute to traffic calming.
