Innovative light for Austria’s most modern tunnel.

The Kaisermühlentunnel in Vienna is the most traveled tunnel in Austria—and now also the safest. This is ensured by video cameras, microphones, the AKUT alarm system and around 1,600 SITECO tunnel luminaires. Best vision and best visual comfort. The new lighting also supports how the eye adapts to the visibility conditions in the tunnel with powerful tunnel entrance lighting. Luminance cameras measure the brightness in front of the tunnel and regulate illuminance inside the tunnel in real time.
