This study will provide better information about the effectiveness of rural roadway safety countermeasures with a focus on lane departures. The main emphasis of the research is to conduct a crash surrogate analysis for common road departure events and develop a model that can be used to predict and mitigate road departures. The purpose of the study covered in this report was to explore use of naturalistic driving study (NDS) data to assess the relationship between roadway and other characteristics and lane departures on rural two-lane roads. Road departure events from an NDS dataset from the University of Michigan Transportation Research Institute (UMTRI) were used to predict the likelihood of a lane departure as influenced by driver, roadway, and environmental factors.
