Overview of Safety Countermeasures for Roadway Departure Crashes

A roadway departure (RwD) happens when a vehicle leaves the traveled way (crossing an edge line or a centerline). Many safety countermeasures have recently been implemented by states to mitigate RwD crashes. This paper presents a summary of various case examples that provide transportation practitioners with a good understanding of RwD safety countermeasure effectiveness. Fourteen case studies involving three categories of countermeasures (signs, pavement safety, and roadside design) were used to review effectiveness.
