About the research

Lane departure crashes account for a significant number of motor vehicle crashes and fatalities. However, information specific to large truck lane departures is not well documented. This project evaluated lane departure crashes and the related independent variables and attempted to derive causal relationships that can be used to identify preventative measures for reducing large truck lane departure crashes.

Data from the Federal Motor Carrier Safety Association?s Large Truck Crash Causation Study (LTCCS) Database were evaluated to determine both the common causes and the circumstances leading to lane departure crashes. Causes and circumstances may include driver, vehicle, roadway, and environmental factors. Simple statistics, a simple odds ratio, and logistic regression were used to evaluate the crashes, and driver, vehicle, environmental, and roadway factors contributing to large truck lane departure crashes were identified.
