24 Intersections Built Around 6m Roadside Poles
A practical Sydney smart traffic package can be scoped as 24 intersections equipped with 6m dark grey hot-dip galvanized steel L-arm poles. The pole height fits compact urban approaches where signal heads, sensing, lighting, and roadside compute must share constrained road reserves without pushing equipment into larger mast-arm formats.
Greater Sydney provides the operating context: 5,638,830 residents as of 30 June 2025, with 75,230 people added during the 2024-25 financial year. The metro area also includes 203 km² of high and very-high-density population grid area, which makes corridor-level sensing more relevant than isolated signal hardware upgrades.
Sensing, Edge Compute, and Network Stack
Each pole integrates four always-on modules: a 4K AI camera, 77GHz mmWave radar, LED fill light, and LED signal head. The camera layer is specified for 98% detection accuracy, 45+ object or event detection types, and under 50ms edge response. Radar adds non-visual motion sensing for rain, glare, night operation, and partial occlusion cases where camera-only detection can degrade.
| Engineering item | Specification |
|---|---|
| Deployment size | 24 intersections |
| Pole format | 6m dark grey hot-dip galvanized steel L-arm |
| Per-intersection pole count | 4-12 poles |
| Camera performance | 98% accuracy, 45+ detection types, <50ms edge response |
| Radar | 77GHz mmWave |
| Network context | 4,860 NSW traffic signals by late 2025 |
The roadside compute layer uses NVIDIA Jetson hardware and connects into a five-layer architecture: Perception, Edge AI, 5G/fiber backhaul, TrafficGPT, and Apps. For procurement teams, that means the package is not only a camera-and-pole bill of materials. It is a distributed sensing and control architecture intended to feed adaptive decision logic, alerts, and application workflows.
Fit with Sydney Signal Operations
Sydney already operates in a mature adaptive-control environment. SCATS NSW reported benchmark reductions of 28% in travel time, 25% in stops, 12% in fuel consumption, and 15% in emissions, with installations across 60,000+ intersections, 200 cities, and 30 countries. A SOLARTODO deployment profile for Sydney should therefore complement the existing signal-management layer rather than replace it.
The strongest use cases are dense corridors such as Haymarket, Chippendale, Ultimo, Parramatta, transport interchanges, and growth areas in the north-west and south-west. Roadside perception can support pedestrian detection, incident auto-alerts, adaptive signal control AI, and, where required, emergency vehicle preemption. Commercially, the recommended model is EPC turnkey, with NTCIP and GB 25280 compliance specified for traffic signal communication and equipment requirements.
