Preview Geometric design of roads handbook
Transport Engineering W Geometric o Geometric design covers the design of the visible elements of the road— l h its horizontal and vertical alignments, the cross-section, intersections and u t interchanges. Good practice allows the smooth and safe flow of traffic as e Design of Roads r well as easy maintenance. Geometric design is covered in depth. The book also addresses the underpinning disciplines of statistics, traffic flow theory, economic and utility analysis, systems analysis, hydraulics and drainage, Handbook capacity analysis, coordinate calculation, environmental issues and public transport. o G f A key principle is that we need to recognise what the driver wishes to do rather than what the vehicle can do. The book takes a human factors approach to e R design, drawing on the concept of the ‘self-explaining road’. It also emphasises o the need for consistency of design and shows how this can be quantified, and o m sets out the issues of the design domain context, the extended design domain a concept and the design exception. The book is not simply an engineering d manual, but properly explores context-sensitive design. e s t Changes in geometric design over the last few years have been dramatic and r far-reaching and this is the first book to draw these together into a practical Hi c guide which presents a proper and overriding philosophy of design for road a and highway designers and students.

This book is dedicated to my wife, Helen, who spent many weeks, months and years alone while I was in my study writing it. And also to Dr. Graham LD Ross, who showed me that geometric design is a three-dimensional jigsaw puzzle and is as much art as it is science.
