Monitoring and controlling tunnel traffic

17.07.2013
Tunnel control center
Safety is a key priority when designing and building a tunnel. All information relating to the equipment used in the tunnel and traffic conditions converges at the tunnel control center.

From there, both the states of all technical systems in the tunnels and the traffic situation are observed and monitored.

An automatic video detection system identifies vehicles which have stopped or are traveling in the wrong direction, pedestrians, sudden vehicle speed changes, tailbacks and even foreign bodies on the roadway.

An alarm system then automatically activates the emergency signal in the control center so that appropriate action can be taken.

In addition to the video detection system, the formation of smoke or an increase in carbon monoxide levels can also be identified by an integrated detection system.

And a communication system provides drivers with safety and warning information on variable message signs. The systems automatically detect traffic volumes and weather conditions and update the electronic traffic signs to match the circumstances. Reference Number: PN 2013.09


Tunnel control technology from Siemens is used around the world

One of Siemens’ first tunnel projects was the 15-kilometer Arlberg tunnel in Tyrol some 30 years ago. Since then, Siemens has equipped so many tunnels in the world that, placed end to end, they would extend around 500 kilometers. The company also played a key role on one of Europe’s largest tunnel projects, the Bolaman-Persembe highway. The 28-kilometer four-lane road between the towns of Bolaman and Persembe, which includes 40 bridges and five tunnels with a total length of 4,600 meters, is an important connecting roadway on the Black Sea. Siemens technology ensures the efficient and safe operation of the five tunnels, one of which, the Nefise-Akcelik tunnel, is the longest in Turkey at 3,800 m. The 350-kilometer four-lane road along the Black Sea coast from Espiye to Sarp on the border with Georgia encompasses a main control center and seven control substations for a total of 29 tunnels, as well as the required technical infrastructure, including traffic management, fire protection, communication and video surveillance.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
