Overview of Australian Standards for Road Lighting

Overview of Australian Standards for Road Lighting
Energy SA Road Lighting for Local Government Forum

• Alec Fisher, Chair of Standards Australia Road
  Lighting Committee

2
Basic Principle

• It is axiomatic that all discussion and decisions
  about road lighting are based on fulfilling the
  performance requirements of the Australian / New
  Zealand Roadlighting Standards AS/NZS 1158
  series.

3
Standards

• There are long and well established Australian
  Standards for road-lighting - an important public
  service
• Dichotomy of lighting -
• for traffic routes (for vehicle drivers - high
  light level - 30 reduction in night road
  accidents - ?1/4 lighting points ? 1/2 cost)
• for local roads, paths, public areas (for
  pedestrians - low light level - safety and
  security - ? 3/4 lighting points ? 1/2 cost)
• A/NZS 1158 -
• Part 1.1 Category V lighting 1997 with 5
  categories - V3 the norm
• Part 3.1 Category P lighting 1999 with 5
  categories - P5/4 the norm
• Both V3 and P4/5 are modest lighting levels

4
How do the Standards Arise?

• The Committee represents all stakeholders -
  Standards Aust provide only logistic support
• Work initiated by outside request and Committee
  decision
• Committee drafts, discussion and consensus
• Use of experience, research and international CIE
  recommendations
• Outside input and transparency through public
  review
• Regular review, amendment and revision - an
  evolutionary process

5
Format of Standards

• They specify performance in terms of light
  technical parameters and their values
• eg. V3 - average carriageway luminance
  (brightness) - 0.7 cd/m2
• Compliance is demonstrated by using specified
  computer design and documentation
• All performance values are in-service initial
  values will be higher
• Continuing compliance is assured by a design
  maintenance regime
• The designer cannot use a maintenance factor of
  gt0.7
• The performance Standards do not refer to
  equipment but there is on Guide

6
Lighting Installations

• Road type, operating characteristics gt light
  level, environmental parameters (control glare,
  spill and waste light)
• Cat V - Light carriageway and verge.
• HPS compromise between efficacy and colour.
• Semi glare control gt economic spacing S/H ? 5
• Cat P - Light whole road reserve.
• P5 one light on every 2nd pole S/H ? 12
• For high risk of crime gt high light level S/H ? 5
• 40 Watts of fluorescent light on every other pole
  has never met the Australian Standard
• All night burning gt Benefit - cost positive

7
Energy Use Minimisation in Road Lighting

• Design
• choose appropriate lighting category gt
  client/designer involvement
• design to minimum L requirements
• design to minimise energy use, purchase on system
  basis
• Luminaire
• highest DLOR and IP rating (maintenance factor)
• Lamp and Control Gear
• highest efficacy (not LPS) compatible with
  operational needs
• optimise lamp wattage in design
• Cat. V - HPS norm but MH city centres
• Cat. P - use white light in P4/5 (eye
  sensitivity) - 80W HPM replacing fluoro (passes
  Standard) - better use high efficacy Fluoro in
  high DLOR luminaire as it becomes available
• Maintenance
• minimise compatible with in-service requirements
  of Standard and max MF 0.7 and lamp life
