Abstract: "This study develops an integrated multivariate econometric framework that simultaneously models the frequency and severity of behavior-related crashes, specifically those involving alcohol, distraction, and aggression. Unlike traditional approaches, the framework captures multiple behavioral dimensions and their sequential linkages, recognizing that one risky behavior can intensify another. Using Oregon’s 2022 crash data, the model uncovers significant behavioral interdependencies often overlooked in planning-level studies. The proposed approach improves both predictive accuracy and interpretability, identifying high-risk zones characterized by truck exposure, rural road dominance, and varying speed limits. These insights provide a data-driven foundation for targeted, behavior-specific safety strategies and proactive crash prevention."
