This Standard specifies 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.
It gives the basic formulae for the LTPs and the associated grid of points (i.e. the calculation field) over which the calculation is to be made. The source code of one computer program, designated SAA STAN, together with a shell program designated STANSHELL, is given for the calculation of the LTPs for Category V lighting on straight sections of road.
This Standard also includes the general requirements for computer programs used to calculate LTPs for other road and public space elements in both Category V and Category P lighting, luminaire light distribution and road surface reflection input data and computer program test data.
1 Refer to AS/NZS 1158.1.1 and AS/NZS 1158.3.1 for information on the types of road for which Category V and Category P lighting, respectively, are appropriate.
2 It is expected that persons using this Standard will have some expertise in lighting design and be familiar with the nature of computer-generated data.
3 The requirements regarding the use of the program SAA STAN are described in Section 4 and other relevant information is given in Appendices A, B and C.
