Intelligent Transport System

Intelligent Transport System (ITS) refers to the application of computer and communication technologies to manage transport problems.

The rapid advances in ITS technologies have enabled the collection of data or intelligence which provides relevant and timely information to road managers and users. Our aim is to utilise the various information gathering technologies to solve the many transport challenges that face us in Western Australia and to make our roads smarter.

ITS systems are already in use in Australia and around the world through Managed Freeway schemes, electronic tolling, driver information through GPS systems, CCTV and Variable Message Signs (VMS).


Current ITS Systems

To assist road users we gather and provide ITS data through a number of mechanisms including traffic cameras, freeway speeds, road conditions around the state and congestion levels, all available on our website.  Other systems currently in place and their benefit tor road users can be viewed below.

​ITS Treatment ​Key Benefits

​Traffic and Incident Monitoring

Devices such as vehicle detectors and CCTV cameras provide real-time traffic information and visibility of road conditions.  They are used by us to detect, verify and manage incidents and congestion on the road network.

  • ​Improved Safety
  • Reliability
  • Efficient Response                                         

Variable Message Signs (VMS)

Electronic roadside VMS can provide a number of on-road services including, advance warning to drivers of congestion, incidents or roadworks and real time travel times to destinations.  They can also be used to provide advice on public transport and parking services

  • ​Informed travel choices
  • Reliability

​Variable Speed Limits

Electronic signals either above traffic lanes (as seen on the Northbridge Tunnel) or on roadsides, such as Beaufort Street Mt Lawley can display variable speed limits.  The speed limit can be reduced to take in to account things such as pedestrian traffic, incidents or roadworks

  • ​Improved safety

Lane Use Management Signals

Electronic signals (as seen on the Northbridge tunnel) indicate the status of a lane to road users, for example: lane open, proceed with caution or lane closed

  • ​Improved safety

ITS Master Plan



  • Improved safety: Many crashes occur due to the stop-start nature of traffic in congested areas.  ITS Technologies can be used to smooth traffic flows and reduce accidents.  Information provided through ITS can also be used to direct traffic away from incidents and alert emergency services as soon as an incident occurs.
  • Improved economic productivity, traffic efficiency and reduced congestion: Congestion lowers productivity, causes flow-on delays in supply chains and increases the cost of business.  ITS has the ability to increase productivity, finding innovative ways to get the most out of our existing road infrastructure.
  • Improved environmental quality and energy efficiency: By smoothing out traffic flows and reducing stop-start conditions, ITS also has the potential to reduce fuel consumption and greenhouse gases.
