A comprehensive review and analysis of the human factors research associated with the implementation of crash warning system interfaces has led to the development of guidelines intended to be used by anyone responsible for the conceptualisation, development, design, testing, or evaluation of in-vehicle crash avoidance systems, especially for forward collision (headway warning), lane change (blind-spot warning), and road departure warnings. This book is intended to highlight issues to be addressed and provide guidance in the development of Collision Warning Systems (CWSs). Information is presented on a variety of topics relevant to the driver-vehicle interface (DVI) of CWS devices.
