SAGE Automation was engaged by Transurban for the installation and commissioning of 80 customised Lane Use Management System signs for two live and critical tunnels in Melbourne.

"Throughout the process, we were really impressed with the documentation being maintained on-site and the diligence being shown from the health and safety perspective, which has been recognsied internally."Challenge
The Burnley and Domain Tunnels in Melbourne, part of the CityLink Tollway, are critical for the passage of commuters from east to west, bypassing the Central Business District. The tunnels and associated ITS infrastructure form part of Transurban’s network.
The Burnley Tunnel (3.4km), and the Domain Tunnel (1.6km) both consist of three traffic lanes. Prior to the project, the tunnels utilised limited side-mounted variable speed limit signage and basic overhead lane control signage nearing end-of-life.
After almost 20 years, the existing lane control signage was in urgent need of upgrading and this provided an opportunity to transition to a fully featured lane use management system.
Solution
Transurban engaged SAGE Automation to design, supply and install 80 custom Lane Use Management System signs for the Burnley and Domain tunnels.
SAGE was responsible for:
- Conducting all works in an operational tunnel/toll road environment
- Decommissioning of existing signage
- Design and mechanical engineering for new signage and controllers
- Manufacture of all required signage and related hardware
- Offsite factory acceptance testing (FAT) of all hardware and software features
- Installation and commissioning (SAT) of new lane use management system.
Signage underwent a stringent testing process to enable faster rollout within the tunnel. A significant amount of pre-testing and controller installation was completed without the need for lane or tunnel closures.
This provided certainty for Transurban and minimised disruption to traffic that relies on the tunnels to reduce their commute time.
Outcome
SAGE Automation completed the commissioning of the lane use management system in both tunnels in December 2020.
Transurban now has a lane use management system within the tunnels which is consistent with the wider open road network, providing a seamless and more familiar experience for customers.
Capability demonstrated
- ITS installation within tunnel environments
- ITS commissioning within tunnel environments
- Sign controller integration into existing OMCS
- Design and mechanical engineering
- FAT and SAT
- Project and construction management.
