The evidence suggests that international jurisdictions which have made the most progress in reducing human trauma (fatalities and injuries) from road crashes have done this by taking a safe system approach, i.e., making improvements across all three major areas: driver behaviours, road design, and vehicle design and safety, as well as building a road transport system that allows for human error. This book presents current research in the study of traffic safety, including using systems analysis to improve traffic safety; transport related issues and concerns in developing countries; electronic stability control; and new trends in road traffic safety.
