A kinetic energy model of two-vehicle crash injury severity

▶ The paper outlines the development of a modelling approach aimed at measuring the injury severity to people in two-vehicle road crashes. ▶ The factors contributing to the speed change (ΔVs) of a subject vehicle are identified using the law of conservation of momentum. ▶ A Log-Gamma regression model is fitted to measure ΔVs of the subject vehicle based on the identified crash characteristics. ▶ A Log-Gamma regression model is used to estimate the Injury Severity Score of the crash from the calculated kinetic energy, crash impact type, presence of airbag and/or seat belt and occupant age.
