Infracontrol has received a repeat order for the development, extension and management of a national road traffic equipment system. The system is used to control, monitor and collect data from ITS installations nationwide such as variable speed signs, congestion alert systems and traffic detour systems. There are currently around 50 installations connected to the system and many more will be connected over the next few years. The new agreement will be valid until May 31, 2023 with an option for a further three years.

Infracontrol has participated in the development of the system since 2012. Johan Höglund, Infracontrol’s CEO, is looking forward to the continued extension and further development of the system.

“This type of system is our specialty and it’s immensely pleasing that the agreement safeguards our continued extension and development of the system together with the Transport Administration. ITS equipment forms a natural part of the road traffic environment, where it both improves road safety and the natural environment, so it’s important that the operation and management of such systems be carried out as simply and efficiently as possible to make sure they work as they should.”

A system for all types of traffic equipment

The Swedish Transport Administration owns and administers a great amount of ITS equipment. Much of it forms part of larger installations such as tunnels and traffic control systems and the equipment is controlled and monitored there. But there are also many smaller freestanding ITS installations right across the country such as variable speed limit signs and congestion alert systems.

The Swedish Transport Administration has introduced a new national platform for control, monitoring and data collection to simplify and streamline their administration. Infracontrol has participated in the development of the platform since 2012. Johan Gunnarsson is the project manager for the ongoing assignment:

“Previously, there were many subsystems used to control, monitor and collect data from all of this traffic equipment. Since the uniform, nationwide system was introduced, the connection of new equipment and day-to-day work have been made easier.”

In order to use as many current applications and solutions as possible, the platform – known as TUS2 – is based largely on the Transport Administration’s existing subsystems.

The congestion alert system on the E6 north of Gothenburg is one of the systems connected to the national platform.

Many installations

TUS2 was set up to create a uniform, national system platform for small-sized traffic equipment and to create conditions for its integration into the national traffic management system, NTS. The traffic equipment concerned is located nationwide. Typical examples include:

  • Variable speed limit installations
  • Minor detour systems on the surface road network or bridges
  • Reversible lane systems
  • Congestion alert systems
  • Small traffic information signs
  • Booms
  • Weigh stations & Inspection stations
  • Wildlife warning systems

Simple user functions

An important aim of the national platform is to achieve simpler, more uniform management of the different types of traffic equipment. The user functions were designed by Infracontrol in collaboration with the Swedish Transport Administration:

“TUS2 is used for operating and controlling function modes, monitoring status and technical alarms, the collection of log data as well as certain traffic logic. It’s extremely important that users are able to handle this easily and safely,” says Johan Gunnarsson.
