Our capabilities

We are focused on being the infrastructure partner of choice for government by providing effective and innovative solutions that lead the world in sustainable road networks. We do this through our core capabilities:

Network planning & forecasting

To maintain the efficiency of our roads, we employ a team of dedicated transport network planners and traffic modelling experts.

They are responsible for:

  • developing network models for the cities in which we operate and identifying and assessing the impact of usage trends and population growth on our roads
  • researching how improvements to a road or surrounding network will affect traffic and revenue
  • providing information that will help us develop our portfolio


Our engineers oversee the operations and maintenance of our roads to ensure optimal performance now and into the future.

The engineers' responsibilities range from maintaining all aspects of road infrastructure and technology systems to monitoring the roads from within our operation centres and responding to incidents. These vary from minor issues such as vehicle breakdowns to major incidents requiring the response of emergency services.

With more than 7,000 incidents a year on our Melbourne roads alone, we've made significant operational improvements to increase traveller safety. These include electronic speed and lane control, specialist tunnel safety systems and automatic detection of incidents to ensure rapid response.

Customer management

With more than five million account customers using our roads and tolling products each year, we continue to evolve our account management systems to ensure ongoing customer satisfaction across our cities of operation.

We have expanded our online customer services, available across multiple platforms, in response to the increasing shift toward electronic commerce.

Project development & delivery

Working closely with government, we've improved the liveability of the cities in which we operate through a number of successful projects including CityLink in Melbourne, Westlink M7 in Sydney and the 495 and 95 Express Lanes in Northern Virginia (USA).

We've also created additional capacity and tackled inefficiencies through a number of asset enhancements, including $1 billion worth of upgrades to key parts of Sydney's orbital network on the M2 and M5 motorways. In Melbourne, we partnered with the Victorian Government to upgrade the Monash-CityLink-West Gate corridor and improve safety and traffic flow across the city.

We work with our government partners during every project stage, from financing and development to construction and operation. We believe there are significant advantages to public-private sector partnerships, including:

  • sizeable private-sector investment
  • substantial risk deferred from the public sector
  • tangible positive outcomes for the community
  • scope for government to fund other priorities

Technology application

Our transport networks handle hundreds of millions of trips annually. In Melbourne, our CityLink tunnels alone record more than 40 million trips a year.

To effectively manage these networks we employ advanced systems and technologies on all our assets.

We were pioneers of multi-lane, free-flow tolling on CityLink in the late 1990s and have continued to develop technologies at the forefront of the industry, including:

  • 3D video systems on our tolling gantries based on military-grade technology originating from missile guidance systems
  • roadside vehicle detection systems on our 495 and 95 Express Lanes (USA) that utilise state-of-the-art laser technology derived from the defence industry
  • dynamic tolling on our Express Lanes which changes the toll price according to traffic. The algorithm controlling the system was four years in development and takes into account minimum speed requirements, traffic density in tolled and general-purpose lanes, the number of high occupancy vehicles and available entry and exit points
