This paper describes the results of a survey to determine the streetlighting research needs of u.S. Utilities. The survey involved 163 utilities belonging to the edison electric institute and the american public power association. The results of the survey were divided into three areas, covering theoretical research, equipment/productdevelopment, and information and technology transfer. Analysis of the responses indicated a substantial need for theoretical research in the areas of glare, driver visual requirements, and night accidents versus lighting studies to establish a firm basis for design standards. Equipment needs were many, beginning with operation of the high pressure sodium lighting system and covering a multiplicity of equipment problems. The area of information and technology transfer covered training and maintenance procedures as well as a variety of legal and other complaints regarding streetlighting. A great need for information transfer between companies is evident. This paper appearsin transportation research record no. 1247, Visibility criteria forsigns, signals, and roadway lighting.
