The situation is well known in the IT world: Various organizations have implemented, operated and renewed systems to support their processes over the years. They have done their job well, the systems have served their purpose at a reasonable cost. These organizations are now being merged for a variety of reasons. It no longer makes sense to run several different systems supporting the same process. The homogenization of the system landscape that now follows often leads to friction with the operators of the previous systems. They now have to live with a new system that is no longer tailor-made and therefore requires a certain willingness to compromise. The Federal Roads Office has carried out such a transformation in the years following the takeover of the national roads from the cantons.
In addition to roads, bridges and tunnels, Switzerland's national road network also includes a large number of electromechanical installations that serve traffic management and tunnel safety. Some of these installations, known as operational and safety equipment (OSS), are visible to road users - for example, the tunnel lighting, the emergency call pillars and the large text displays. However, there are other systems that operate in the background, including video surveillance, fire alarm systems and ventilation systems in the tunnels. The flawless functioning of these systems is constantly monitored. As soon as technical faults occur, they are reported to the responsible personnel via the operations control center.
The Federal Roads Office (FEDRO) has been responsible for all these systems since 2008; previously, responsibility lay with the cantons. The question arose as to how FEDRO should deal with an electrical and IT infrastructure that was originally created by 26 cantons. It seemed obvious to standardize the installations throughout Switzerland in order to be able to guarantee efficient traffic management, among other things. But how does one go about achieving this goal? Ultimately, the operating and safety equipment must perform reliably around the clock, every day. Eraneos was able to accompany FEDRO on part of this journey as part of the System Architecture Switzerland (SA-CH) project.
