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: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...

Im Focus: New nanomaterial can extract hydrogen fuel from seawater

Hybrid material converts more sunlight and can weather seawater's harsh conditions

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF...

Im Focus: Small collisions make big impact on Mercury's thin atmosphere

Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers.

Recent modeling along with previously published results from NASA's MESSENGER spacecraft -- short for Mercury Surface, Space Environment, Geochemistry and...
