SUNUP REDUCES COST OF HIGHWAY LIGHTING

An investigation and analysis is reported which was instrumental in improving the clarity of contracts as well as reducing the ultimate costs of the agreements. The research consisted of 3 phases: analysis of energy rate structure and trends, analysis of alternative illumination levels, and development of strategies for negotiaton and operation. The calculation of fuel costs and of fuel adjustments is illustrated. Various alternatives such as turning off every other light and changing the wattage of luminaires were evaluated according to ANSI standards. Turning off all highway lighting during summer months, and reduced lighting from midnight to 6:00 a.m. were also investigated. One alternative for improving illumination levels was to replace low efficiency luminaires with high efficeincy units (mercury vapor or high pressure sodium) and with high mast lighting. Decisions on maintenance by contract or by state crews were clarified by the contract, which separated the costs of energy from the cost of maintenance. Policy statements concerning types of lighting as well as allowable levels of illumination were established on the basis of the research results.
