Abstract:

Low Pressure Sodium (LPS) roadway illumination systems of 35, 55, 90, 135 and 180 watts were studied and compared to Mercury Vapor (MV) and High Pressure Sodium (HPS) roadway illumination systems. Systems of 180-watt LPS, 400-watt HPS, and 1000-watt MV, and systems of 135-watt LPS, 250-watt HPS, and 400-watt MV are compared with respect to photometries, visual acuity, disability veiling glare, and energy savings. Actual photometric data, including isolux curves are shown as measured on a simulated roadway.
