Analysis of Naturalistic Driving Study Data: Roadway Departures on Rural Two-Lane Curves

Rural curves are known to pose a significant safety problem, but the interaction between the driver and roadway environment is not well understood. Thus, the objective of this research was to assess the relationship between driver behavior and characteristics, roadway factors, environmental factors, and the likelihood of roadway departures on rural two-lane curves. To accomplish this, data from the second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study (NDS) and Roadway Information Database (RID) were used to develop relationships between driver, roadway, and environmental characteristics and the risk of a roadway departure on curves. This research was tailored to address four fundamental research questions: What defines the curve area of influence? What defines normal behavior on curves? What is the relationship between driver distractions; other driver, roadway, and environmental characteristics; and risk of roadway departure? Can lane position at a particular state be predicted as a function of position in a prior state? Since four fundamental research questions were addressed, a different methodology was developed specific to each. In addition to the analytical method, the data sampling and segmentation approach, general variables considered, results, and implications are discussed for each question.
