Safety in tunnel systems

17.07.2013
Fire protection, alarms and evacuation

Every tunnel has its own, unique safety requirements depending on the location, design, height and level of traffic. Even seemingly insignificant events can rapidly escalate in tunnels. That’s why automatic alarm systems reliably identify and monitor objects and situations which may cause accidents or fires.

If safety regulations are violated, the video-based system triggers the alarm, e.g. in the event of traffic congestion, wrong-way drivers or lost cargo. As in all fire situations, rapidly localizing the source of the fire is a critical factor of success for efficient damage limitation.

Video smoke detection systems improve the risk analyses of tunnel operators and response forces, as they enable them to collect valuable information on the nature of the smoke and changes in the tunnel. Self-rescue is one of the outstanding priorities when accidents occur in tunnels.

Communication systems which enable immediate dispatch of emergency services and the announcement of escape instructions are therefore critical to reducing the risks for tunnel users.

Tunnels: Integrated safety for integrated traffic networks

Siemens is using the Hagerbach Test Gallery in Flums (Switzerland) for research purposes and for testing various fire scenarios and the effectiveness of fire protection measures in tunnel systems under realistic conditions (1:10 scale).

In tunnel applications, security and safety are inseparably intertwined. Given the limited escape routes in a tunnel, it is essential to detect a problem as early as possible.

Whether the aim is protection from potential attack, identification or disturbances in traffic flow, or detection of a fire, two central functions are always needed: detection and management.

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Research icebreaker Polarstern begins the Antarctic season

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Coping with errors in the quantum age

Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
