Traffic engineering is a field of civil engineering which uses engineering techniques for achieving the safe and efficient movement of passengers and goods. It is focused on safe and efficient traffic flow by using innovation in road geometry, traffic lights and traffic signs, and through the design of sidewalks, crosswalks, road surface markings and cycling infrastructure. Traffic flow management can be long-term or short-term. Traffic problems can largely be addressed by developing intelligent transportation systems, such as by integrating sensors to measure traffic flows, as well as interconnected and automated guidance systems to manage traffic. An important area of traffic engineering is highway safety engineering, in which factors such as road user psychology, vehicle dynamics and human factors engineering are taken into account to reduce the incidence of crashes. This book provides comprehensive insights into the field of traffic engineering. It traces the progress of this field and highlights some of its key concepts and practices. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
