The aim of this book is to present pedestrian injuries from a biomechanical perspective. We aim to give a detailed treatment of the physics of pedestrian impact, as well as a review of the accident databases and the relevant injury criteria used to assess pedestrian injuries. A further focus will be the effects on injury outcome of (1) pedestrian/vehicle position and velocity at impact and (2) the influence of vehicle design on injury outcome. Most of the content of this book has been published by these and other authors in various journals, but this book will provide a comprehensive treatment of the biomechanics of pedestrian impacts for the first time. It will therefore be of value to new and established researchers alike.
