Network Operations

About the Transport network operations team

The ARRB transport operations team provides services relating to the operation of transport networks including roads, freeways, car parks and related technologies. We investigate the strategies and technologies for efficient and safe movement of people and freight. For example ARRB provides services and advice that address issues such as:

  • the performance and measurement of a road traffic system so that congestion can be managed equitably and in real time
  • determining needs for vehicle detection, classification and identification, and the best technologies to meet those needs
  • evaluating available technologies and schemes for telematics applications
  • determining the sort of road advisory information that should be conveyed to travellers and how it can be provided
  • improving the productivity and reliability of arterial and freeway networks
  • improving the level of service for trucks, on-road public transport vehicles and emergency vehicles
  • improving safety and efficiency of off-road car parks.

Members of the team have also prepared Intelligent Transport Systems (ITS) strategies for road authorities and developed innovative schemes for the measurement of road network congestion and its management.

The transport operations team works closely with ARRB’s transport safety and traffic, transport economics, transport planning and management and heavy vehicles teams to develop tailored solutions that meet client needs. The team draws upon ARRB’s expertise and resources from across Australia.

Microsimulation resources

The management of a road network often requires the forecasting of the impacts of implementing various traffic management measures. Microscopic simulation traffic modelling is still an emerging science and practitioners skills and experience within the jurisdictions is still developing. The following link gives access to technical note bulletins and case study documents and functions, compiled into the one PDF as a replacement to the former Microsimulation Hub website.
