How Risky is It? An Assessment of the Relative Risk of Engaging in Potentially Unsafe Driving Behaviors Purpose of Current Study • To investigate the relative risk associated with a variety of potentially-risky behaviors including speeding, distracted driving, aggressive driving, and driving while drowsy. Methodology • Researchers analyzed data collected under the previous 100-Car Naturalistic Driving Study (100-Car Study). In the 100-Car Study, a sample of 109 drivers in the Washington DC / Northern Virginia region were monitored continuously over a period of 12-13 months using in-vehicle cameras and “black box” technology. • During the study, 82 crashes, 761 near-crashes, and 8,295 other driving-related incidents were captured. Note: for the purpose of this study a crash was defined as any time a vehicle collided with a fixed object or other vehicle. • Data from these events as well as from normal “baseline” driving were used to compare the prevalence of specific driver states (e.g., fatigue) and behaviors (e.g., speeding) during crashes, near-crashes, and normal driving, to estimate the relative crash risks associated with specific states and behaviors.
