The Kaisermühlen tunnel is located on the A22 in Vienna (Austria). This is the longest city tunnel in Vienna with a length of 2.2 km. With a daily throughput of more than 125,000 vehicles, it is also the busiest in all of Austria. With three main lanes, two secondary lanes and 10 ramps in the tunnel, this makes the highest demands.

Renovation under traffic at night
The operating and safety facilities are being renewed under traffic. All work in the tunnel takes place at night, with only individual lanes being blocked. All components are installed and put into operation parallel to the existing running system.
The challenge of tunnel ventilation
Due to the large number of lanes, secondary lanes and ramps, tunnel ventilation is extremely complex. With a special tunnel simulator, the ventilation can also be tested in the simulation mode with traffic, so that the commissioning phase is reduced.
Highest safety category – high available system
All control components and communication networks are designed as a high-availablity system.
