Abstract

When a vehicle leaves the roadway, the likelihood of a roadway departure crash is high and these crashes can be deadly. Roadway departure crashes usually involve a single vehicle, and they occur after a vehicle crosses an edge line, a centerline, or otherwise leaves the designated traveled way and collide with another vehicle or with a fixed object or overturns. This study investigates the nature of the interrelations between roadway, vehicle, and driver (characteristics and behavior) risk factors in roadway departure conflicts. The purpose of the study is to examine which factors might increase the risk of a roadway departure crash and which types of circumstances increased the likelihood of a fatality during crash. The data came from the Second Strategic Highway Research program (SHRP2) which included the Naturalistic Driving Study (NDS) and Roadway Information Database (RID), which followed a cohort of drivers in six different states from 2010-2012.
