The O-Bahn is now equipped with state of the art C-ITS technologies that are designed to reduce congestion and handle the city’s growing population.
Adelaide, South Australia, Australia
Adelaide’s O-Bahn is one of only a few guided busways and busway tunnels in the world. The rapid transport system allows buses to travel along rail-like corridors to avoid normal road traffic, while having the ability to move onto normal roads. The unique design brings passengers much closer to their last mile destinations than trains or rail. The O-Bahn transports approximately 30,000 passengers every weekday between the CBD and the city’s north-eastern suburbs.
Since the O-Bahn’s inception in 1986, the city has experienced significant growth. Vehicle movements on the Hackney Road/Botanic Road intersection were reported to be at capacity with around 79,000 vehicle movements on an average weekday. The flow-on effects were obvious: the on-road section of the O-Bahn between Gilberton and the CBD was experiencing congestion and was affecting the reliability of service times.
SAGE provided a turnkey solution for the main works contractor McConnell Dowell, ensuring the safe and efficient operation of the new 670-metre O-Bahn tunnel and its approaches. SAGE designed, manufactured, installed and commissioned the systems required for the intelligent transport system (ITS), tunnel control, fire-life safety, ventilation, deluge pumping, and power monitoring systems.
Careful consideration was given to reducing whole-of-life costs for the tunnel, in particular: energy efficiency, life expectancy, routine maintenance requirements and local supportability.
Local design and manufacture of panels at SAGE’s Advanced Manufacturing Facility ensured they were delivered on time to a world standard quality.
The O-Bahn is the only busway tunnel in the southern-hemisphere and is now equipped with these state of the art C-ITS technologies, designed to reduce congestion and handle the city’s growing population.
“Our local partnership with SAGE was an important factor in the award of the O-Bahn City Access Project. With its reputation for similar, successful projects across Australia, McConnell Dowell and Department of Planning, Transport and Infrastructure (DPTI) knew that SAGE could drive innovation through the project using its local experience.”
