When you are responsible for a highway network, you cannot simply replace your intelligent transportation system (ITS) every time technology changes.

The system has to keep working while the network evolves. New traffic patterns, roadworks, changing infrastructure, and advances in detection technology all need to be managed without losing the capabilities operators already depend on.

In highway ITS, trust is ultimately operational: knowing that critical systems can continue to perform while technology, infrastructure, and requirements evolve around them.

A trusted partner helps protect that continuity by understanding operational priorities, building on existing investment, and introducing new capabilities without requiring wholesale replacement of the existing system.

Technology that keeps pace with the network

Highway ITS is constantly developing. Thermal imaging can help maintain detection when challenging conditions such as darkness, fog, and snow affect conventional visible-light cameras. Intelligent detection and AI can help identify incidents and provide operators with more information. Control-room software can bring alerts and video together to support faster assessment and response.

But adding technology is only part of the challenge.

For operators, new capabilities need to work with existing infrastructure and established ways of working. Software upgrades need to preserve essential functionality. Detection needs to adapt as traffic patterns and road layouts change.

During roadworks or contraflow operations, for example, monitoring requirements can change as lanes and traffic movements are reconfigured. An effective ITS needs to adapt to those changing conditions while continuing to provide operators with the information they rely on.

The goal is not simply to have newer technology. It is to have an ITS that can keep supporting the operation as the network changes.

20 years of evolution on the A75

The A75 through France's Massif Central provides a real-world example.

FLIR and DIR Massif Central have worked together for 20 years as the A75 ITS has evolved to meet changing operational requirements. The network includes 320 km of motorway, five tunnels, 130 cameras, and operational teams managing around 21,000 interventions each year.

During that time, the system has evolved from conventional monitoring to incorporate thermal imaging, embedded AI, automatic incident detection, and modern control-room software.

That evolution has supported changing operational requirements, including congestion, roadworks, and contraflows, where detection needs to adapt to how traffic is moving.

The important point is not simply how much the technology has changed. It is that new capabilities have been introduced while protecting the operational continuity and existing investment that the network depends on.

Partnership built for the long term

That kind of continuity depends on more than the technology installed on day one.

Preventive maintenance, remote diagnostics, technical support, and system updates help keep an ITS aligned with operational requirements over time. A long-term partnership also builds knowledge of the network, its infrastructure, and the people operating it.

That accumulated knowledge matters when requirements change. It provides a stronger foundation for modernisation, helping new capabilities to be introduced while preserving the systems and processes that already work.

As Benoit Beaufreton, Head of Maintenance at DIR Massif Central, puts it:
"These are the systems that once you have them, you simply can't do without."

Building for what comes next

For highway operators, the question is not only which ITS technology is available today. It is whether the technology, expertise, and support behind it can continue to deliver as the network changes.

The A75 shows what is possible when an ITS evolves with the operation, protecting continuity while introducing new technology and capabilities over time.

For infrastructure owners planning the next stage of their ITS, that ability to evolve may be just as important as the technology selected today.
