ECONOMIC AND ACCIDENT POTENTIAL ANALYSIS OF ROADWAY LIGHTING ALTERNATIVES

THE OBJECTIVE OF THIS STUDY WAS TO INVESTIGATE COST-EFFECTIVENESS RELATIONSHIPS FOR VARIOUS ROADWAY LIGHTING DESIGN CRITERIA AND ROADWAY GEOMETRY. LIGHTING DESIGN CRITERIA (EFFECTIVENESS), CONSISTING OF AVERAGE ILLUMINATION, AVERAGE-TO-MINIMUM RATIOS OF ILLUMINATION, AND MAXIMUM-TO-MINIMUM RATIOS OF ILLUMINATION, WERE APPLIED TO ROADWAY GEOMETRY CONFIGURATIONS OF FOUR, SIX, EIGHT, AND TEN TRAFFIC LANES. FIVE ILLUMINATION DESIGN ALTERNATIVES WERE SELECTED AND COMPARED ON THE BASIS OF THE DESIGN CRITERIA FOR THE VARIOUS ROADWAY CONFIGURATIONS. COST DATA USED IN THE STUDY INCLUDED INITIAL, MAINTENANCE, OPERATIONAL, AND ACCIDENT COSTS. COMPARISONS WERE MADE ON A COST BASIS FOR THOSE DESIGNS THAT GAVE A PARTICULAR LEVEL OF EFFECTIVENESS FOR A SPECIFIC ROADWAY. TABLES SUMMARIZE THE COST-EFFECTIVENESS RELATIONSHIPS. HIGHER MOUNTING HEIGHTS WERE BOTH MORE EFFECTIVE AND LESS EXPENSIVE. BREAKAWAY BASES GIVE LARGE BENEFIT COST RATIOS, WHATEVER THE ILLUMINATION DESIGN, IF ILLUMINATION UNITS ARE EXPOSED.
