Lighting Problems in Highway Traffic : Proceedings of a Symposium Held at the Wenner-Gren Center, Stockholm, Sweden, October 1962

Lighting Problems in Highway Traffic provides information pertinent to the problems in highway traffic. This book discusses a very complicated system of problems of greatest significance for road safety during dark hours. Organized into 11 chapters, this book begins with an overview of the information capacity of the human eye that is dependent on physiological, physical, and psychological factors. This text then examines the part played by the vision in the driving of vehicles. Other chapters consider the visual acuity, which varies greatly with the luminance of objects, with their contrasts, and with the presence of uneven luminosity conditions such as one encounters on the highways. This book discusses as well the difference between the illumination concept and the luminance concept in road and street lighting. The final chapter deals with the design of lower headlight beams. This book is a valuable resource for experts in different fields of lighting research. Content: Front Matter, Page iii Copyright, Page iv OPENING ADDRESS, Page 1, PROFESSOR Y.
