RELATING DESIGN, ECONOMIC ANALYSIS, AND ENERGY CONSERVATION TECHNIQUES IN HIGHWAY LIGHTING

Analysis of highway lighting for four basic interchange geometrics (cloverleaf, diamond, half-cloverleaf, and Trumpet) using the four most common highway lighting sources (Mercury, metal halide, high-pressure sodium, and low-pressure sodium) reveals that designs using metal halide and high-pressure sodium sources at conventional mounting heights are less expensive than mercury or low pressure sodium at a rate of 3.158found/kWH. High mast lighting designs were analyzed for comparison. However, on the average, when the power rate exceeds 10.5found/kWH, the low-pressure sodium lighting design becomes the most economical system. The full-partial lighting system is discussed and it is noted that it results in a 50 percent power saving for the majority of the lights, whereas the cost of additional circuits and control devices amounts to 2 percent of the initial installation cost. The results of 13 installations, summarized in a table, indicate an average power cost saving of 36 percent as compared with the total power cost for lighting interchanges throughout the night.
