Abstract:

The basic requirements for nighttime roadway visibility are reviewed, and a table of recommended values for roadway lighting of city streets is presented. The values are based on five classifications of streets and a separate category for intersections. The primary standard of measurement is roadway luminance, but illumination and glare values are shown as parallel requirements. The recommended values for roadway lighting are less than the current American Standard Practice (RP-8, 1978) values but have more stringent quality specifications. Thus, it is shown that vision on roadways can be equal to or better than current practice and energy use can be appreciably reduced, by as much as 50-60 percent in some cases. Data for a study project in Portland, Oregon, are reviewed to demonstrate that the recommendations are achievable and that energy and cost reductions are practical. (Author)
