World-wide, vehicle safety experts agree that significant further reductions in fatalities and injury numbers could be achieved by deploying appropriate passive (or crash) safety strategies. The FP6 APROSYS Integrated Project (IP) answers to this call by development and introduction of critical technologies that improve passive safety for all European road users for priority accident types and levels of crash severity. The field of passive safety concerns in particular human injury biomechanics, vehicle crashworthiness and protection systems. APROSYS is mobilizing and integrating the European scientific & technological expertise for the development of new technologies for the protection of road users in all relevant accident conditions. Furthermore, this IP aims to increase the level of competitiveness of the European industry by developing new safety technologies. Its main goal is to create tools to improve knowledge and passive safety techniques for the road safety.
