Moreton Bay to Trial Australia’s First AI Traffic Lights at 1 Petrie Intersection

Summary
Later this year, the City of Moreton Bay will test an AI-powered traffic light system at a Petrie intersection north of Brisbane, marking Australia’s first such trial.
The system would use sensors, traffic data and outside inputs such as weather or major events to adjust signals in real time instead of relying mainly on fixed rules.
Pittsburgh’s pilot cut travel times 25%, waiting 40% and emissions more than 20%, but the Queensland trial also raises questions over whether cars, buses, cyclists or pedestrians should get priority.
Cybersecurity is another risk: US researchers attacking a 100-light network showed hackers could freeze signals or alter timings, prompting calls for backup fixed modes and human override.
As cities adopt smart traffic lights, what happens when hackers decide to cause chaos?
When an AI referee controls the road, how will it decide who gets the green light first?
Smarter Signals, Smoother Cities: How AI Traffic Lights Are Transforming Australia’s Urban Mobility
Overview
Australia has launched its first AI-powered traffic light trial in the City of Moreton Bay, Brisbane, aiming to transform traditional fixed-timing signals into a dynamic, responsive system. Led by the local council, the initiative uses SWARCO's ImFlow AI, which continuously learns from live traffic data and adapts signals in real time. This approach is designed to make journeys more efficient, safer, and environmentally friendly for all road users. By leveraging reinforcement learning, the system maintains a comprehensive overview of vehicles at intersections, optimizing traffic flow and reducing unnecessary delays.
