A roadway departure (RwD) crash is defined by the Federal Highway Administration as a crash in which a vehicle crosses an edge line, a centerline, or otherwise leaves the traveled way. These crashes, comprised of run-off-road (ROR) and cross-median/cross-centerline head-on collisions, tend to be more severe than other crash types. The reasons for ROR events are varied and include the driver attempting to avoid a vehicle, an object, or an animal in the travel lane; inattentive driving due to distraction, fatigue, sleep, or drugs; the effect of weather on pavement conditions; and traveling too fast through a curve or down a grade. This paper intends to provide a brief overview of a series of cost-effective improvements as an easy-to-read resource for preventing vehicle departures from roadways. This article summarizes a recent publication by the American Traffic Safety Services Association that can help transportation agencies better understand the effectiveness of each RwD safety countermeasure and prioritize the implementation of countermeasures.
