Tunnel under the Ljubljana castle, LJUBLJANA, SLOVENIJA

The tunnel under the castle is one of the spots in Ljubljana that we have been taking care of for decades. In addition to lighting maintenance, we also take care of the maintenance and control of all tunnel systems through our own SCADA system. The system was developed in-house and receives regular security checks.

Tunnel lighting requires greater attention and flexibility. Adequate management, which is carried out by Javna razsvetljava d.d. (JRL) is crucial to the operation and safety of the tunnel.

The SCADA system enables control and management, and an overview of what is happening in the tunnel, and through smart algorithms, adjusts the lighting to the actual lighting conditions outside the tunnel.

Flue gases and visibility in the tunnel are also monitored. Multi-level alarms allow for faster and better intervention and faster elimination of errors, thus serving better traffic safety in the tunnel.
