DigiTS – Digitala tvillingar för trafikstyrning

Traffic control system is a more modern and more accurate term for what was previously called rail signaling system.

A traffic control system has more functionality regarding control of an entire fleet of trains and not just pure safety.

Signal systems still occur as a term, but are more valid for older types of systems.The traffic control system enables dense traffic with good safety and consists of the functions maneuvering, safety logic and speed monitoring as well as support for train driving.

Its main task is to prevent trains from colliding with other trains, and to prevent trains from running faster than the surroundings allow.The control system in the traffic management requests the route for the train, signal safety logic guarantees a safe route, the gear drive shifts for the road to the left and right and locks the switch, track lines detect trains and communicate train protection (speed monitoring).

Optical signals visually inform the driver.The traffic control system is closely dependent on rail vehicles and drivers via the driver panel for train protection (speed monitoring).Systems for rail traffic are complex, built up of several subsystems that need to be managed as a whole in order to meet future developments and challenges.

Some types of rail-borne traffic are classified as socially important activities, which places demands on long-term solutions.There are strong connections between the traffic control system and the environment in which it operates.

Very simply, it can be described as the traffic control system getting the many components of the infrastructure to talk to each other and to the rail vehicles.

There is much more than the traffic control system that contributes to high capacity, which can have a greater effect on changes than just a changed traffic control system can achieve.

For example, how vehicles and platforms are designed and how many stations, tracks and switches there are.New traffic control systems are digital with a high degree of automation, which means that operators in traffic management and drivers can receive extensive support in their work, especially when unexpected situations arise.

The trains can be run automatically, corresponding to eco-driving for cars, with effects such as increased comfort, less wear and lower energy consumption, while regularity and timetable can be maintained.In the longer term, there are opportunities to introduce driverless operation where the trains can be run more flexibly, connected and connected according to current traffic needs and parked along the tracks to handle sudden changes in the surroundings.

Flexible traffic is valuable for maintenance and other work on the tracks. For the largest possible gear ratio, work vehicles and depot areas also need to be equipped with traffic control. By extension, machine learning can also be used.

Digital systems can also exchange information with other digital systems.When the traffic control system detects some form of failure, safety always comes first.

Technical safety control is a methodical and systematic way of working to ensure that the work with signal systems and traffic control systems is carried out correctly.Today, there are several digital tools that can support the work from start to finish.

However, in order to have exchange and learning throughout the process, which includes technical and financial decision-making throughout the life cycle, new applications of building blocks, tools and working methods are needed.
