Adelaide’s O-Bahn tunnel officially re-opened this week, after an extensive upgrade that makes it one of the world’s smartest tunnel systems.
The O-Bahn uses cooperative intelligent transport systems (C-ITS) and civil construction to improve travel times and reliability for users.
Working for main works contractor McConnell Dowell Australia, SAGE Automation delivered the C-ITS technologies that communicate to the tunnel’s control systems and provides benefits to bus services, for example:

SAGE installed and integrated the tunnel sensors as well as delivering the other ITS and Operation Management and Control Systems (OMSC) and Plant Management and Control Systems (PMCS).
SAGE also manufactured the Main Distribution Boards at its Advanced Manufacturing Facility at Tonsley Innovation Precinct.

While the ITS technologies remain invisible to commuters they are the key to solving congestion on our roads.
“It’s a huge credit to all involved in this complex infrastructure project,” Transport and Infrastructure Minister Stephen Mullighan said.
“The tunnel is a critical piece of infrastructure which will make bus trips on our busiest public transport network faster and more reliable, while also freeing up more road space for cars and other vehicles, particularly on the Inner City Ring Route,” he said.
The upgrade was part of the State Government’s $160 million O-Bahn City Access Project and is expected to reduce travel times for the 30,000 people who use the service every day.

Integrating the technologies of tomorrow with current infrastructure is one of the biggest challenges road authorities face. SAGE engineers, manufactures and integrates connective data solutions for Addinsight – the South Australian Department for Planning, Transport and Infrastructure's traffic intelligence system that provides real-time road traffic analysis of probe data from Bluetooth, WiFi and other sensor technologies.
