Abstract:

A roadway departure (RwD) crash happens when a vehicle leaves the traveled way (crossing an edgeline or a centerline). These crashes, comprising run-off-road (ROR) and cross-median head on collisions, tend to be more severe than other crash types. In 2013, RwD crashes accounted for 56 percent of all motor vehicle traffic fatalities. Inattention or fatigue, an avoidance maneuver, or traveling too fast are the common reasons a driver may leave the travel lane. Roadway and roadside geometric design features (e.g., lane and shoulder widths, horizontal curvatures, sideslope, and clear zones) play a significant role in whether or not human error results in a crash. To achieve the Federal Highway Administration’s (FHWA’s) Toward Zero Deaths vision, many safety countermeasures have recently been implemented by state departments of transportation and local agencies to mitigate RwD crashes. This paper presents a summary of various case examples to provide transportation practitioners with a good understanding of the effectiveness of RwD safety countermeasures.
