Austroads has released new guidance outlining how fibre optic sensing can be applied across road networks and what agencies need to consider before adopting it. The report sets out where the technology is already delivering results, where it is still developing, and how to assess whether it is the right fit for different purposes in transport operations.
Fibre optic sensing can use cables already installed along roads to detect vibration, temperature and strain. While commonly used for communications, its use as a sensing tool in transport is still developing.
Some applications are already in use, such as tunnel fire detection, where the technology enables continuous monitoring and precise location of incidents. Other applications, such as traffic monitoring, are still developing but show potential to provide continuous data along entire corridors rather than at fixed points.
Austroads Transport Network Operations Program Manager Amy Naulls said the report helps agencies make practical decisions about using the technology.
“The report finds that performance depends on how and where fibre is installed. This means the technology is not suitable for every situation and agencies need to match it carefully to their needs and network conditions.”
“This report presents a range of options to improve network operations by interpreting information obtained through fibre optics – and some of these options could be progressed quickly by using fibre optic cable which is already in the road reserve”.
Ms Naulls added “the real value of fibre optic sensing comes from what agencies do with the data. Data analytics and signal processing capability turn raw sensor output into useful operational insights.”
The research also points to the need for updated standards, improved installation approaches and stronger collaboration with industry to enable wider adoption. Building on this, it gives agencies clear direction on where to focus. It distinguishes between applications that are ready for use today and those better suited to trials or further development.
