Specifies the computer based procedures applicable to Category A lighting for use in the derivation of installation design data or for the direct calculation of light technical parameters to determine compliance with the requirements of AS 1158.1. It describes the use of a computer program, designated SAA STAN, for the calculation of light technical parameters on straight sections of road. The source code for the program, on a 13 cm IBM-formatted flexible disk (designated AS 1158.2S), is provided with the Standard. The program is written in the FORTRAN language and complies with Subset FORTRAN 77. The disc contains a text file which gives information on the implementation of the program. Information on the use of the program for road lighting calculations is given in AS 1158.2.

This standard specifies the computer-based design procedures applicable to Category A lighting (see Note 1) for use in -(a) the derivation of the installation design aids described in AS 1158.1, i.e. luminaire spacing tables, luminaire performance tables and isolux diagrams; and(b) the direct calculation of light technical parameters, where required, for the design or evaluation of road lighting in accordance with the requirements of AS 1158.1.This standard describes the use of a computer program, designated SAA STAN, for the calculation of light technical parameters for straight sections of road. The source code for the program is available on a 13 cm IBM-formatted flexible disc as AS 1158.2S. A copy of the disc is provided in a pocket inside the back cover of this standard.NOTES:1. See AS 1158.1 for information on the classes of road for which Category A lighting is 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 use of the program SAA STAN is described in Section 4 and other relevant information is given in Appendix B.
