• Description:
  A methodology is developed for the evaluation and optimization of societal costs of two-vehicle automobile collisions. Costs considered in a Figure of Merit include costs of injury/mortality, occupant compartment penetration, collision damage repairs, and costs of engineering modifications. The Figure of Merit is developed in a statistical setting, taking into account present (or projected) vehicle popu­lation and collision mix statistics, including distributions of vehicle weight/size classes, collision modes, and collision speeds. The methodology is implemented with first-order cost models for the several cost components. Simplified models are utilized for two-vehicle collision dynamics, vehicle force-crush characteristics, and restraint systems. A comp??ter program is developed for the optimization of vehicle force-crush characteristics and crush distance design to minimize th?? Figure of Merit.
