Abstract
Most problems that would benefit from motor vehicle risk analysis involve questions about the importance of design features or other characteristics of vehicles relative to factors related to drivers, driving environments, and types of collisions. Outcomes of motor vehicle accidents result from interactions among several or more pre-crash and at-crash factors. The inherent complexity of motor vehicle accidents often defeats traditional approaches to multivariate regression analysis. This paper introduces a new technique called crash scenario analysis. Rather than treating many causal factors as discrete variables, combinations of factors define crash scenarios. A single variable (scenario risk) measures the likelihood of crash outcomes for vehicles involved in each unique scenario. The authors applied crash scenario analysis to vehicle rollover and used logistic regression to estimate the importance of vehicular factors relative to scenario risk. Findings indicated that scenario risk was a much stronger predictor of rollover in fatal crashes than vehicle static stability factor (T/2H).
