[Current]Lighting for roads and public spaces, Part 2: Computer procedures for the calculation of light technical parameters for Category V and Category P lighting
The objective of this Standard is to specify the computer-based design procedures applicable to Category V and Category P lighting for the calculation of light technical parameters (LTPs), as required, for the design or evaluation of road lighting in accordance with the requirements of AS/NZS 1158.1.1 and AS/NZS 1158.3.1.
