Abstract:In 1964, the Texas Transportation Institute initiated a research project, "Supplementary Studies in Highway Illumination," under the sponsorship of the Texas Highway Department in cooperation with the U. S. Bureau of Public Roads. The ultimate goal is the research is to produce definite criteria for the design of a visual environment which is conducive to safe and comfortable night-time driving. To accomplish this goal, it is necessary to determine the relationship among all of the factors within the environment. The interactions among visibility, visual comfort, brightness patterns, light distributions, and the configuration of the lighting system must be examined. The purpose of this report is to present the results of a study of the effects of system configuration on light distribution.
