TUNNEL AIRPORT TEGEL (TFT), motorway A111, Berlin, Germany

, 2008


Up to 90,000 vehicles use daily the tunnel “Flughafen Tegel” and have an according impact on the road. Opened for traffic in 1979, the approx. 1000 m long tunnel is part of the city motorway A111 in Berlin.

During a general renovation the tunnel was expanded and equipped with up-to-date traffic and safety technology.


The traffic management system contains tunnel control, road control and the integration of the tunnel into a network control system. The tunnel control reacts to different requirements from the facility management system (e.g. fire alert), traffic monitoring (e.g. congestions) and traffic situation (e.g. construction sites).

The complete control, monitoring and operation is realised with the central control software. The hardware and software is located in the operation building TFT. The system is connected via different interfaces and user stations with the existing traffic management centres in Berlin:

  • “Verkehrsrechnerzentrale” at Stolpe
  • “Verkehrsregelungszentrale der Verkehrs-lenkung Berlin“ at the airport Tempelhof
  • “Tunnelleitzentrale” in the TFT building
