Jagdberg tunnel
10th Heusch/Boesefeldt sub-centre in Thüringen

With the release of the southern carriageway of the Jagdberg tunnel on the A4 at Jena on November 18th 2014 the 10th tunnel with a sub-centre provided by Heusch/Boesefeldt was opened to traffic.

The tunnel, which is situated between the junctions Magdala and Jena/Göschwitz, has two separate tubes with three tracks each and a length of about 3,1 km.The sub-centre is based on the tunnel sub-centre software which is based on the Heusch/Boesefeldt product GeoDyn2and was first introduced in the Eichelberg tunnel in 2005 and has thus been constantly improved and modernised. 

What we are dealing with here is a completely redundant hard- and software environment with a hot stand-by operation and an automatic switch-over from primary and secondary system and vice versa. The system has interfaces to the traffic control, the operational host computer and the Superordinate Traffic Computer (ÜVR) which has also been provided by Heusch/Boesefeldt.

The sub-centre manages the traffic control systems in the tunnel and the tunnel access areas and the roadside variable message signs at the junctions Magdala and Jena/Göschwitz. The control measures are a product of manual, semi-automatic and automatic requirements of the traffic control and the tunnel operations.Through the connection to the ÜVR a coordinated control of the tunnel chain Jena (Jagdberg tunnel and Lobdeburg tunnel, former noise abatement measures Jena) is made possible.

We are looking back on a long-standing successful cooperation with the Thüringer Landesamt für Bau und Verkehr (Thuringian State office for Construction and Traffic) which started 2002 with the setting-up of the traffic computer Kammquerung. Further sub-centre systems in the tunnels Eichelberg, Lobdeburg, Behringen, Schmücke, Höllberg, Pörzberg, Alte Burg, Berg Bock and Germany’s longest road tunnel, the Rennsteig tunnel, with a length of 7.916 m were to follow.
