Abstract
This paper describes the development of a pedestrian head impact test procedure which can be applied to central hood regions of motor vehicles. Based on these measurements, and on clearances measured under those impacts where HIC values were less than 1000 on the twelve- vehicle sample, it is concluded that with little or no additional research and development effort, head injury severity could be reduced in the U.S. by designing all vehicle hoods to have similar impact responses to those of the best performing production vehicles.
