The Middle Ring goes six feet under

With up to 120,000 vehicles per day the Middle Ring is the most heavily loaded main road in Munich. Anyone traveling in the southwest of Munich via the Middle Ring, or by the motorway to Garmisch-Partenkirchen, has to go through here. But with the end of July 2015, most of the cars disappeared six feet under and Munich received open spaces and green areas at the surface.

Complex ventilation and traffic control

A fire inside the tunnel is a horror scenario and the ventilation and traffic control system has to fulfil high requirements. Besides a fast localisation and detection of the fire, complex programmes are of paramount importance for the regulation of the traffic and the tunnel ventilation. In case of a disaster these programmes automatically introduce actions that are of vital importance for the safety of the drivers.
