A TOTAL DESIGN PROCESS FOR ROADWAY LIGHTING
THE DESIGN PROCESS FOR ROADWAY LIGHTING INVOLVES COMPLEX INTERRELATIONS AMONG VISUAL INFORMATION NEEDS, WARRANTING CONDITIONS FOR LIGHTING, GUIDELINES FOR LIGHTING DESIGN, AND COST-EFFECTIVE PRIORITIES FOR FUND EXPENDITURES. THIS PAPER PRESENTS A LIGHTING PROCEDURE BASED ON INFORMATION NEEDS OF NIGHT DRIVERS AS RELATED TO THOSE INTERRELATIONS. A FRAMEWORK, CONSISTING OF INFORMATION NEEDS PRODUCED BY VARIOUS TRAFFIC FACILITY CHARACTERISTICS, IS ESTABLISHED FOR DEVELOPMENT OF THE DESIGN PROCESS. THE INFORMATION NEEDS ARE PRESENTED AS THE REQUIREMENTS TO BE SATISFIED BY ROADWAY LIGHTING, AND THE TRAFFIC FACILITY CHARACTERISTICS PRODUCING THE NEEDS SERVE AS THE JUSTIFICATION OR WARRANTING CONDITIONS FOR THE INSTALLATION OF LIGHTING. THE NUMBER OF WARRANTING CONDITIONS IS USED AS THE DETERMINANT OF DESIGN CRITERIA AND THE BASIS FOR COST-EFFECTIVE PRIORITIES. A PRIORITY MODEL IS PRESENTED BASED ON LIGHTING EFFECTIVENESS (THE REDUCTION OF WARRANTING CONDITIONS THROUGH THE USE OF ROADWAY LIGHTING), VEHICLES OR PEOPLE SERVED, LIGHTING INTENSITY, ROADWAY MILEAGE OVER WHICH THE PEOPLE ARE SERVED, AND TOTAL ANNUAL LIGHTING COSTS. THE PRIORITY MODEL FAVORS THOSE FACILITIES WITH HIGH WARRANTING CONDITIONS THAT CAN BE LIGHTED MOST ECONOMICALLY. IT IS CONCLUDED THAT THE TOTAL DESIGN PROCESS IS A RATIONAL APPROACH THROUGH WHICH CURRENT PRACTICES CAN BE REVISED.
