Road Lighting: Fundamentals, Technology and Application

This book outlines the underlying principles on which modern road lighting is based. The objective of the book is to leave the reader with an understanding of the background of the subject and a knowledge of how these principles should be applied in practice. The book is divided into three parts. The first part discusses the lighting of open roads for motorized traffic as well as for cyclists, pedestrians and residents. The first chapters deal with the purpose of road lighting, visual performance, including the effects of mesopic-vision and the aging eye, and visual comfort. Traffic safety, personal security and pleasantness are the main issues of the first part of the book. The second part of the book focuses on the subject of light pollution. Lighting that lights not only the area intended but that spreads out uncontrolled into the surrounding areas and into the sky is an annoyance to society. The third part of the book details tunnel and underpass lighting.
