When a vehicle leaves the traveled way and encounters a pavement-shoulder drop-off, it can be difficult for the driver to return safely to the roadway. As the driver attempts to steer back onto the pavement, the side of the tire may scrub along the drop-off, resisting the driver's attempts. The safety edge is an innovative treatment intended to minimize drop-off-related crashes.
A road diet involves narrowing or eliminating travel lanes on a roadway to make more room for pedestrians and bicyclists. While there can be more than four travel lanes before treatment, road diets are often conversions of four-lane, undivided roads into three lanes — two through lanes plus a center turn lane. This study resulted in the development of crash modification factors for this engineering treatment.
