34、ting, ANSI/IES RP-8-2014, but is included for informational pur-poses only.)During the 85-year existence of the IES Committee on Roadway Lighting, the night use of public ways has grown greatly. Traffic has changed in speed and density. Studies have established a substantial relationship between goo
35、d fixed lighting and traffic safety. In addition, understanding of the principles of good lighting has advanced. The following earlier publications of the committee reflect progress of the roadway lighting technique through the years. Principles of Streetlighting 1928 Code of Streetlighting 1930 Cod

38、ighting (reaffirmed 2005) 2000The present Practice has evolved from these earlier documents, and considers the latest research, interna-tional standards, experience, and equipment technology.An American National Standard represents the consensus of all groups having an essential interest in the prov
39、isions of the Standard Practice. The IES, as a sponsor, must have the viewpoints of groups interested in roadway lighting represented on the Roadway Lighting Committee.1.0 INTRODUCTION1.1 Purpose of this Standard PracticeThe primary purpose of this Standard Practice is to serve as the basis for desi
40、gn of fixed lighting for roadways, streets, adjacent bikeways, and pedes-trian ways. The Standard Practice deals entirely with lighting design and does not give advice on construction. Its primary purpose is to provide rec-ommended practices for designing new continuous lighting systems for roadways
41、 and streets. It is not intended to be applied to existing lighting systems until such systems are completely redesigned. It has been prepared to advance the art, science, and prac-tice of roadway and street lighting in North America. Roadway and street lighting includes pedestrian and bikeway light
42、ing when it is associated with the public right-of-way.In those circumstances where there is any doubt as to whether the provision of new or updated roadway lighting would provide a benefit at a particular location, a decision should be made based on a study of local conditions. Once a decision has
43、been made to provide lighting, this publication provides the basis for design-ing an appropriate system. The AASHTO Lighting Design Guide provides guidance for warranting.1.2 Purpose of Roadway and Street LightingThe principal purpose of roadway and street lighting is to allow accurate and comfortab
44、le visibility at night of possible hazards in sufficient time to allow appro-priate action. For a pedestrian, this can mean better visibility of the surrounds and the sidewalk, while for the driver of a motor vehicle, it will mean time to stop or to maneuver around an obstacle. Good lighting has bee
45、n shown to significantly reduce the night pro-portion of accidents; especially on urban freeways and on major streets. For most streets and side-walks, good lighting has been reported to increase the feeling of personal security of pedestrians.The benefits of lighting should be considered against th
46、e drawbacks; engineering, capital and mainte-nance costs, energy use, appearance-particularly of overhead wires, but sometimes also of poles-the added fixed object hazard of poles, plus spill light on adjacent residential or commercial (i.e., outdoor din-ing) property and into the sky (affecting ast
47、ronomi-cal observations). Thus, lighting is good when it is economical in equipment, energy and maintenance costs, and meets a proven or reasonably predict-able need, with a minimum of adverse effect. This Practice has been developed to provide guidance to experienced engineers in designing such lig
48、hting.2ANSI/IES RP-8-141.3 Roadway Lighting and Street LightingTwo different types of roadway lighting systems are defined in this recommended practice - roadway lighting and street lighting.Roadway lighting is provided for freeways, express-ways, limited access roadways, and roads on which pedestri
49、ans, cyclists, and parked vehicles are gener-ally not present. The primary purpose of roadway lighting is to help the motorist remain on the roadway and help with the detection of obstacles within and beyond the range of the vehicles headlights.Street lighting is provided for major, collector, and local roads were pedestrians and cyclists are generally present. The primary purpose of street lighting is to help the motorist identify obstacles, provide adequate visibility of pedestrians and cyclists, and assist in visual search tasks, both on
