Behind Norway's traffic management and road safety

Norway is a country built on tunnels and bridges. With over 1,100 road tunnels stretching more than 800 kilometres and nearly 20,000 bridges, ferry quays and load-bearing structures, no other country has bent its road network so radically around its geography. Western Norway, where our client Trafsys is headquartered, is the heart of this network.

About Trafsys

Trafsys is a Norwegian technology company based in Bønes (Bergen) that has, for decades, delivered systems for road and tunnel safety, efficiency and reliability. They specialise in critical road traffic infrastructure — emergency telephony, monitoring, and intelligent traffic management.

The challenge

The terrain in Norway is demanding: steep grades, single-tube tunnels, fjord crossings 290 metres below sea level, polar nights in the north, and ice and storms most of the year. And yet Norway has been Europe's safest country for road users for ten consecutive years.

How? Norway adopted Vision Zero in 2001 — a parliamentary commitment to reach zero road deaths by 2050 — backed by the safety, communication and traffic-management systems that make it possible. This is the world Trafsys has been building tools for since long before "smart infrastructure" was a buzzword.

Designed for critical moments

Trafsys' portfolio consists of four products:

  • Trafvision — the software through which the Traffic Management Centre gets an overview of the situation and manages the response
  • Trafview — camera surveillance for operators
  • Trafsense — detects deviations in the traffic flow and notifies the Traffic Management Centre in real time
  • TrafAirwaves — in-tunnel radio systems that send messages directly to car radios

The company's philosophy centres on the moment when "every second counts". In Norway's long single-tube tunnels, the official safety doctrine is the self-rescue principle — drivers must be able to evacuate on their own before emergency services arrive.

Trafsys's systems are designed around this: SOS phones connect drivers directly to the Traffic Management Centre, in-tunnel radio overrides car radios with instructions, variable message signs guide traffic away from the incident, and cameras give operators a continuous overview.

How Itera delivers value

Innovation

Some parts of the system were written about 25 years ago. Since then, Norway's vehicle fleet has grown by more than 50%, and over 200 sites have been (re)constructed. This requires changes not only in the approach to collecting data from sites, but also in how that data is turned into user-readable interfaces.

The core module of the system, the Alarm functionality, where operators can see events that happened across the country in a matter of milliseconds and process them as necessary, is being recreated from scratch. We brought in the latest technologies to ensure stable, secure, and testable software that can last and grow to meet future needs.

A new design language, together with an in-house component library, shortens the path to every action, keeps critical information visible, and gives operators room to adapt the interface to how they work.

 

Knowledge

It is crucial to understand how things work in a system of such scale and importance. Layers of multiple technology eras can be seen in the code, alongside outdated or missing parts of documentation. In an environment where "every second counts", there is no place for mistakes  and therefore analysis and tests of functionality takes an extensive amount of time.

To tackle this, we are working on AI-based real-time documentation, which is generated directly from the codebase. Hours of analysis and potential blind spots can now be avoided with well-structured prompts. Results are validated and put together into documentation and tickets by domain experts in a more effective way.

 

Building continuity in systems that matter

The result is a modernised platform designed for continuity, resilience and clarity, supporting those responsible for keeping Norway’s roads safe.

The collaboration with Trafsys reflects a long-term commitment to critical infrastructure. By combining domain expertise with modern software practices and AI‑supported documentation, the solution is being renewed in a way that supports today’s operators while remaining adaptable to future demands.
