Abstract
The authors present a total design process for roadway lighting in which the process involves visual information needs of motorists, warranting conditions for lighting, guidelines for design, and cost-effective priorities for fund expenditures. The priority model presented is based on lighting effectiveness, vehicles served, lighting intensity, and total annual costs. The three discussants of this paper are generally complimentary regarding the extent to which the author's work is useful but suggest areas not considered in their total design process.
