Abstract
A physical model capable of credible simulation of human trauma is badly needed in automobile safety research. Development of such a model has been limited, not only by lack of biological and engineering data, but by lack of a coherent, sequential plan of attack on the problem. Such a plan, based upon the systems approach, is offered. The plan has two major phases. The first phase includes qualitative analysis, hypothetic modelling, and program planning the second provides for empiric research, system modelling and design, fabrication, and test of a physical model.
