Brisbane will trial artificial intelligence-assisted traffic signals at 22 intersections along Logan Road from early 2027, bringing the new traffic-management system to a major corridor running through Greenslopes. The Logan Road trial will form part of a wider six-month test covering 37 intersections across Brisbane.
The $15 million pilot will also include 15 intersections on the Kelvin Grove Road corridor. Council says the system will analyse traffic conditions and adjust signal sequences with the aim of reducing delays, queue lengths and crashes.
AI to adjust signals as conditions change
The technology will operate through existing traffic infrastructure and use cameras, edge computing and artificial intelligence to monitor road conditions. Cameras will distinguish between pedestrians, cyclists, cars, trucks and public transport while measuring traffic volumes and queue lengths.
Software will use that information to calculate traffic light sequences in real time. Historical traffic patterns, weather and major events can also influence how the system responds as conditions change.
Council transport chair Ryan Murphy said human operators would remain involved in managing the network. About 20 staff at Brisbane’s Metropolitan Traffic Management Centre currently make manual interventions, while the new technology is expected to provide additional options for responding to changing traffic conditions.
Council has cited results from comparable traffic-management systems elsewhere showing potential reductions of up to 15 per cent in average travel times and 22 per cent in intersection queue lengths. Possible benefits also include reductions of up to 12 per cent in rear-end crashes and 18 per cent in red-light violations. Those figures are projected benefits, with the local trial yet to begin. About 30,000 vehicles use Logan Road each day, according to figures released with the project.
Council says smarter signal management could improve the performance of established roads without relying on major road-widening projects.
Setting traffic priorities
Council will determine the operating rules used by the system rather than leaving the technology to independently decide which road users receive priority. Different parts of the network could therefore be managed according to different transport needs.
Pedestrian movement could receive greater priority in some locations, while freight or other forms of transport could be favoured elsewhere or at particular times. The system will also be able to alter signal strategies during wet weather or major events.
Privacy controls form part of trial
Council says faces, number plates and other personally identifiable information captured by the cameras will be blurred. Data will be stored in Council-owned and managed facilities in Brisbane and will not be sent offshore.
Council has also said identifying information may be made available to law-enforcement authorities following an individual request. Human oversight will remain part of the traffic-management system during the pilot.
Wider rollout depends on results
The 37-intersection trial is scheduled to run for six months before Council decides whether AI-assisted traffic management should be expanded more widely across Brisbane.
Brisbane has about 1,000 signalised intersections, and Council says the results of the Logan Road and Kelvin Grove Road pilot will inform any decision on a broader rollout.
