AS/NZS 1158.1.2:2010
Lighting for roads and public spaces - Part 1.2: Vehicular traffic (Category V) lighting - Guide to design, installation, operation and maintenance
Sets out guidelines for the design, installation, operation and maintenance of lighting systems for roads which require Category V lighting complying with AS/NZS 1158.1.1, i.e. traffic routes, including arterial roads and freeways. It is intended to be read in conjunction with AS/NZS 1158.1.1 and provides background information and advice to assist in the application of the requirements of that Standard.
