"Preface This book describes all areas of vehicle safety: accident avoidance@ pre-crash technologies@ mitigation of injuries@ and post-crash technologies. Special attention is given to driver assistance systems and to compatibility between vehicles in carto- car crashes as well as pedestrian protection. Several countries have achieved a high level of vehicle safety; however@ more than 1.2 million fatalities still occur each year on roadways worldwide. These metrics indicate a continuing need to improve vehicle and road safety. New technologies in sensors and electronic control units and the growing knowledge of car-to-car and car-to-infrastructure technologies have fused the previously separate areas of accident avoidance (popularly known as ""active safety"") and injury mitigation (popularly known as ""passive safety"") into the newer concept of ""integrated vehicle safety."" This new approach represents a further step in reducing accident rates. In this book we detail a significant number of integrated vehicle safety solutions."
