This book provides in-depth information about road user characteristics and highway geometric design. It explains the collection and analysis of different types of traffic data, obtained as part of various studies. It also describes the design of different types of intersections and illustrates the use of road markings and lighting. Recent advances such as Intelligent Transportation System are also explored. This book will be useful to undergraduate and postgraduate students as well as to researchers and practicing engineers.
