A test device has been built that consists of a mobile deformable barrier with the capacity to simulate different configurations and structural behaviors of various car front ends, using foam shapes of various density and moulding. With this barrier, a series of tests were carried out using a standing adult dummy as a pedestrian. The tests were aimed at generally reviewing and identifying the main factors contributing to an effective reduction in pedestrian injuries. As manufacturers, we have obtained information on how to improve both the structures and shapes of striking cars. In testing, research is not restricted to pedestrian car contacts but includes pedestrian/ground impacts to identify a possible correlation between car architecture and pedestrian injury levels in impacts against the ground.
