ECONOMIC STUDY OF ROADWAY LIGHTING

AGENCIES RESPONSIBLE FOR HIGHWAY LIGHTING WILL BE ABLE TO ESTIMATE THE COST OF ALTERNATIVE LIGHTING SYSTEMS MORE ACCURATELY BY USING THE TABLES PRESENTED IN THIS REPORT. DECISION MAKING WILL BE FACILITATED THROUGH THE USE OF COST TABLES, EQUIPMENT SPECIFICATION FORMS AND PROCEDURES, AND COST DATA FORMS. THE TABLES CONTAIN EASILY REFERENCED COST DATA FOR ALL COMPONENTS OF A ROADWAY LIGHTING INSTALLATION- INCLUDING EQUIPMENT, LABOR, OVERHEAD, AND POWER COSTS- FOR CONSTRUCTING, MAINTAINING, AND OPERATING A SYSTEM. LIGHTING SYSTEM CONFIGURATIONS ARE DERIVED WHICH COMPLY WITH RECOMMENDED AVERAGE ILLUMINATION LEVELS AND UNIFORMITY RATIOS FOR THREE DIFFERENT TYPES OF HIGHWAYS. A PROCEDURE IS GIVEN FOR OBTAINING ACCEPTABLE CONFIGURATIONS AND FOR DETERMINING THE APPROPRIATE DISTRIBUTION AND CONTROL EQUIPMENT TO BE USED WITH THESE CONFIGURATIONS. EIGHT COMPLETE LIGHTING SYSTEMS ARE SPECIFIED AND THEIR COSTS DETERMINED FOR THREE DIFFERENT HIGHWAY TYPES' THREE SYSTEMS FOR A TWO-LANE RURAL ROAD, THREE FOR A FOUR-LANE RURAL EXPRESSWAY, AND TWO FOR A SIX-LANE URBAN EXPRESSWAY. COST SPECIFICATION OF THESE CONFIGURATIONS INDICATED THAT USE OF 700- AND 10000- W MERCURY LAMPS AT MOUNTING HEIGHTS OF 35 FT AND HIGHER GREATLY REDUCED COSTS BECAUSE FEWER LIGHTING POLES ARE REQUIRED PER MILE AND COSTS CAN ALSO BE REDUCED BY RAISING THE ALLOWABLE UNIFORMITY RATIO FROM THE PRESENT 3-TO -1 STANDARD.
