Superordinate traffic computer (ÜVR) Thüringen

Coordinated traffic control in the tunnels in Thuringia

Within the scope of the new construction of the Rennsteig tunnel on the A 71 (2003), Heusch/Boesefeldt built the traffic sub-center for the "Kammquerung Thüringen" as a subcontractor of QSG Verkehrstechnik. Subsequently, we were commissioned with the construction of further tunnel sub-centers and the superordinate traffic computer (ÜVR) Thuringia.

Over the years, 12 tunnel sub-centers have been integrated into the superordinate traffic computer. As of 2022, these are: Eichelberg, Lobdeburg, Behringen, Schmücke, Höllberg, Pörzberg, Alte Burg, Jagdberg, Rennsteig, Berg Bock, Hochwald and Rothenstein. Each of the tunnel sub-centers controls one active traffic management system in each direction. For the tunnel chain of the Kammquerung (Alte Burg, Rennsteig, Hochwald and Berg Bock) and the tunnel chain of Jena (Lobdeburg, Jagdberg), the superordinate traffic computer takes on the coordination of the control.

The Erfurt - Halle/Leipzig network control system for the management of the traffic flow on the A4, A71, A38 and A9 highways was put into operation in 2019, and the control system was also integrated into the superordinate traffic computer. The control measures for the network control is coordinated via the federal states of Thuringia and Saxony-Anhalt. The travel times for the control measures are recorded via Bluetooth sensors.

The superordinate traffic computer is a server system consisting of two redundant units, an online database server and an application server. The systems operate in "hot-standby" mode and have a common history database server.

The traffic computer uses information from the tunnel operating technology to control the traffic technology facilities. To do so, the traffic computer is coupled with the tunnel computers of the individual tunnels and the superordinate control technology computer. The operating technology receives aggregated information from the traffic computer.

Traffic data acquisition is done by the connected sensors at 15-second intervals, which is 4 times as fast as usual. This places additional demands on the processing speed and data storage.

The measures for emergencies or catastrophe are the original task of the superordinate traffic computer. Catastrophic incidents are handled in a coordinated manner across the tunnels of the Kammquerung or the Jena tunnel chain and supported with appropriate detour measures via the downstream network. The detours are indicated by the automatic activation of variable message signs. Special simplified operating procedures, adapted to these catastrophes, support fast and error-free processing.
