Next Generation Traffic Signalling Program
The Next Generation Traffic Signalling Program is an initiative aimed at transforming traffic signal infrastructure across Queensland.
By modernising the traffic signal hardware and systems at intersections owned by the department, the program lays the groundwork for the next generation of arterial Intelligent Transport Systems (ITS). This forward-thinking approach seeks to enhance asset management and support the integration of advanced technologies to meet the evolving needs of Queensland’s transport network.
This is the first ITS project of its kind in Australia and will involve the replacement of over 1,400 intersection infrastructure components including controllers, cabinets and lanterns.
The initiative addresses the need to replace ageing equipment that is either at or nearing the end of its serviceable life. Traffic signal hardware and systems are a vital component of the transportation network, and the program aims to maintain a high standard of asset serviceability and operational functionality to meet our commitment to safety and accessibility.
This twofold approach includes:
Next Generation Traffic Signal Controller focussing on upgrading the core signalling equipment, the traffic signal controller and the cabinets in the field, for each TMR signalised intersection. Such upgrades will incorporate state-of-the art field technologies to improve intersection efficiency and safety. The new controllers are also expected to have enhanced connectivity capabilities, essential for future integrations with Intelligent Transport Systems.
The Extra Low Voltage Lantern replacement project is transitioning from low voltage plastic bodied lanterns to aluminium bodied traffic signal lanterns that operate on extra low voltage electrical supplies offering multiple benefits.
Extra low voltage lanterns are typically more energy-efficient, durable and can be safer to maintain. The switch to aluminium bodies also aids in longevity and reliability as they may be less prone to damage from environmental factors.
The Next Generation Traffic Signalling Program will enable the department to leverage advancements in traffic signal hardware and systems technologies to prepare for future demands.
Benefits
- Improves safety
- Improves network efficiency
- Contributes to economy
- Reduces maintenance
Key features
- Replacing an ageing fleet of traffic signal controllers including roadside cabinets.
- Replacing existing low voltage plastic bodied traffic signal lanterns with aluminium bodied traffic signal lanterns that use extra low voltage power.
- Configuration file management software.
- New and updated specifications for traffic signal controllers.
- Preparation for connectivity associated with future connected and autonomous vehicles.
Funding
This program is fully funded by the Queensland Government. Funding is provided through 2 projects, the Next Generation Traffic Signal Controller Project and the Extra Low Voltage Lantern Replacement Project.
Current status
Works have already commenced in the North Coast, Metropolitan, and South Coast regions, with activities set to begin shortly in the Fitzroy and Wide Bay/Burnett Districts.
What to expect
- Due to high traffic volumes at most locations, the majority of works will be carried out at night.
- During construction, speed limits will be reduced, police will be on site directing traffic and reduced numbers of lanes will be in operation.
- Construction will occur incrementally across the state.
Key milestones
- 2024: Rollout of new sites recommence in South Coast, Metropolitan and North Coast districts.
- January 2025: Next generation traffic signal controllers and extra low voltage lanterns set as default technology for all new road upgrade projects.
- March 2025: Upgrade of existing site installations to latest manufacturer firmware completed.
- August 2025: Commence site installations in the Fitzroy and Wide Bay/Burnett Districts.
- December 2025: New configuration file management system in place to manage intersection programming.
