Safety alerts for drivers

Cooperative Intelligent Transport Systems (C-ITS) allow vehicles to communicate with other vehicles and infrastructure, such as traffic signals, that are fitted with the same system. Drivers then receive alerts about upcoming hazards and traffic signal information. The technology is sometimes referred to as ‘connected vehicles’.

How C-ITS works

The C-ITS device sends and receives information to and from other equipped vehicles and infrastructure 10 times a second. It uses that information to determine if a conflict is likely, based on comparing its own location, direction and speed to those of the other vehicles.

Drivers can be warned of risks on the road ahead, over the crests of hills or around bends. International C-ITS trials have indicated these systems can improve safety and reduce congestion.

Trials using C-ITS

The Centre for Road Safety has established Australia's first C-ITS testing facility, known as the Cooperative Intelligent Transport Initiative.
