When it comes to lighting our roads, footpaths, and car parks, one of the most frequently asked (yet surprisingly complex) questions is: How far apart should light poles be placed? While there’s no one-size-fits-all answer, getting the spacing right is critical for safety, energy efficiency, and long-term asset management, especially when you’re working on government-funded or civil infrastructure projects in Australia.
In this article, we’ll walk you through the standard distances, Australian regulations, and the key factors that influence pole placement. Whether you're a civil engineer, asset manager, or construction contractor, this guide will help you better plan and design lighting layouts that meet compliance and perform in the field.
Standard Light Pole Spacing in Australia
In Australia, light pole spacing is generally governed by the AS/NZS 1158 standards, a set of guidelines that cover lighting for roads, footpaths, car parks, and public areas.
Here are the general ranges commonly used:
-
Urban roads: 30–60 metres apart
-
Rural roads: 100–200 metres apart
-
Residential streets: 25–40 metres apart
-
Major arterials or highways: 50–80 metres apart, depending on pole height
-
Pedestrian footpaths and shared pathways: 20–40 metres apart
These distances aren’t set in stone, they’re adjusted depending on several variables such as pole height, light source intensity, and the area’s functional lighting requirements. For instance, a higher pole can spread light over a wider area, which may reduce the number of poles needed.
What Influences Light Pole Placement?
The optimal spacing of poles isn’t just a matter of putting them evenly down a road. A variety of environmental, technical, and functional factors come into play:
-
Pole height and luminaire type: Taller poles cast light further, which can increase spacing. However, higher poles may require stronger foundations or wind load resistance.
-
Road classification: High-speed or high-volume roads typically require brighter and more frequent lighting compared to residential cul-de-sacs.
-
Pedestrian activity: Areas with foot traffic demand a different lux level and more uniform lighting to minimise shadows and improve visibility.
-
Mounting position: Whether the poles are installed on a central median or road verge affects beam direction and spacing calculations.
-
Natural obstructions: Trees, signage, and intersections must be considered to avoid blocked light paths or dark patches.
-
Local council requirements: Many local governments have specific guidelines or deviations from AS/NZS standards.
Different Applications, Different Spacing
Lighting needs vary dramatically based on the application. Below is a breakdown of typical scenarios:
Roadways and Highways
These require careful consideration due to vehicle speed and driver visibility. Lighting is often placed on alternating sides of the road or along a central median. In high-speed zones, poles may be spaced 50–80 metres apart when using 10–12 metre high poles with LED luminaires.
Footpaths and Shared Use Paths
Footpath lighting is designed to improve pedestrian safety and reduce trip hazards. Here, pole spacing is closer, generally around 20–35 metres depending on luminaire height and type. Even light distribution without dark spots is key.
Car Parks
Pole layout in car parks focuses on eliminating dark zones and maintaining even coverage across bays. Spacing can range from 15–30 metres, with poles typically installed around perimeters or on central islands.
Industrial or Commercial Sites
These sites often demand higher lux levels and may integrate smart lighting or solar poles. Spacing here can vary depending on machinery, overnight operations, or site-specific risk assessments.
Meeting AS/NZS 1158 Lighting Standards
The AS/NZS 1158 series defines lighting categories based on the type of area and its intended use:
-
Category V: For vehicle traffic routes (arterial and sub-arterial roads)
-
Category P: For pedestrian areas such as footpaths, shared paths, and minor roads
-
Category PX: Enhanced pedestrian visibility in areas of higher risk
These standards specify not just pole spacing but also vertical and horizontal illuminance, glare control, uniformity, and lighting distribution. Compliance is essential for project approval, safety audits, and long-term liability management.
Choosing the Right Pole for the Job
At Plasgain, we understand that not all poles are created equal. The right pole can directly impact how far apart you can place your lighting infrastructure. Here’s what to consider:
-
Pole height: Taller poles = greater spacing potential but higher material and foundation costs
-
Material: Steel, aluminium, or composite, each offers different strengths for wind zones, coastal areas, and maintenance cycles
-
Lighting source: LED lighting has largely replaced older sodium or metal halide lamps, allowing for wider pole spacing and lower running costs
-
Smart & solar poles: These modern options integrate technology like motion sensors, cameras, or solar panels, which may influence placement flexibility
Efficiency, Safety & Sustainability Through Spacing
The correct pole spacing doesn’t just improve visibility, it also delivers downstream benefits like:
-
Reduced energy use through optimal LED design
-
Lower installation and maintenance costs with fewer poles
-
Improved public safety, including reduced crime and better night-time navigation
-
Reduced light pollution with targeted beam control
-
Alignment with ESG and sustainability targets, a growing priority for councils and developers
Final Thoughts
Getting the spacing right for light poles isn’t just about following numbers in a standard, it’s about understanding your project goals, the environment you're building in, and the outcomes your stakeholders expect. With the right planning, compliant designs, and high-quality pole solutions, your project can meet both functional and sustainability benchmarks.
