At the heart of this operation lies ‘Procesleiding’ (PRL): the core Traffic Control System for traffic management and real-time dispatching. ICT InTraffic has been a long-term partner in the development, operation and evolution of PRL, supporting ProRail in keeping rail traffic safe, punctual and resilient.
Turning operational complexity into control
PRL brings planning and real-time execution together. The system supports traffic controllers during daily operations, planned track works and unexpected disruptions by allocating infrastructure, setting and releasing routes, taking safety measures and dynamically adjusting operations.
PRL’s strength lies in its deep integration into daily operational practice, enabling traffic controllers to stay in control and act effectively, even under pressure.
The ICT InTraffic contribution
With decades of rail-domain experience, ICT InTraffic combines deep operational understanding with advanced software engineering. For ProRail, this means 24/7 availability of mission-critical systems, consistent real-time information across planning and operations, safety-critical software development using the SafeScrum methodology and support for automation where it adds value, while keeping decision-making firmly with the traffic controller.
Modernising legacy systems
Our specialists translate operational information needs into solutions designed and developed according to the latest standards. We continuously improve usability, maintainability and testability, enabling the system to evolve safely over time.
Step by step, we modernise a complex legacy landscape without interrupting the 24/7 operation or compromising safety. By leveraging AI, we also unlock knowledge and insights faster from extensive codebases and documentation for one of Europe’s largest bespoke rail traffic control systems.
This approach shows that large-scale, safety-critical traffic control systems can be modernised without disruptive “big bang” replacements, while continuing to evolve in close cooperation with users and operators.
Designed around the traffic controller
At ICT InTraffic, technology always serves the operator. In PRL, decision-making remains the responsibility of the traffic controller. The system provides the overview, insight and support needed to make the right choices under all circumstances.
By working closely with traffic controllers and operational teams, ICT InTraffic has translated domain expertise into better situational awareness, smarter disruption handling and reduced workload in high-stress situations.
The result is technology that strengthens professionalism and resilience in daily operations.
A reference that extends beyond ProRail
PRL is more than a Dutch success story. It shows that delivering in mission- and safety-critical environments requires specialist knowledge and experience, and that combining operational insight with modern technology leads to better results.
This experience is directly relevant for infrastructure managers, operators and traffic control organisations worldwide facing growing networks, ageing systems and increasing operational pressure.
From national rail networks to complex urban and cross-border operations, ICT InTraffic helps organisations design, build and evolve traffic control systems that perform today and tomorrow.
