The objectives of PRISM are to facilitate the efficient and effective development of "smart restraint systems" to suit European conditions. It recognises that some such technologies are already under development to improve occupant safety during crashes. This project shall greatly assist the development of efficient smart restraint systems, thereby reducing societal costs. It shall also improve the competitiveness of the European motor industry by providing clear guidelines on the functionality and evaluation requirements for such systems. This shall be achieved by using new real world data, bespoke computer models of high-risk scenarios, and a thorough evaluation of their scenarios using a variety of techniques.
