Canton of Valais, Switzerland

The challenge

On behalf of the Swiss Office for National Roads, Bergauer AG renewed the existing traffic guidance system on the A9. By successfully integrating old, existing systems with new road sections and harmonizing the entire system visualization, a homogeneous superordinate guidance system was created. The new system enables smart monitoring, regulation and smooth guidance of traffic on the entire cantonal and national road network with a total of 25 tunnel systems.

The process

On the one hand, the superordinate guidance system serves to direct traffic on the national and cantonal roads of the entire canton, while on the other hand, all technical infrastructures can be monitored and operationally optimized. In addition, preventive measures have been established to prevent system failures, which significantly increase the service life of the technical infrastructure.

With the help of dynamic intervention management, on-call services can react quickly to disruptions and incidents, making the roads in the canton of Valais even safer.

The solution

An innovative control system for tunnel infrastructures has been realized. The new MyTunnel technical control system is characterized by:

• 2 new control centers,
• 27 section computers,
• the integration of around 200 PLC system controllers for all of the 24 tunnel sections
• as well as regional traffic control in the canton of Valais with control of all variable message signs (prismatic) and variable text displays (LED RGB).
