A simulation software from Siemens can analyze people's behavior in emergency situations. The software known as "Crowd Control" calculates how individuals or crowds will behave and move in emergencies. The program allows experts to observe and optimize evacuation and rescue measures in advance and in real time. Making such improvements is one of the most complex tasks that security officers have to perform.
Crowd Control can determine in advance how thousands of people will move, and it does so at a rate that is ten times faster than real life. This improves the planning of buildings and allows security personnel to be trained more easily. Siemens offers building evacuation simulations as an independent consulting service. This service encompasses the entire range of analytical tasks, extending from data collection and data preparation to the generation of reports and the interpretation of the results.
One of the reasons why it is so difficult to plan building evacuations in advance is that conditions change very quickly and dynamically during emergencies such as fires or shootings. In addition, it's hard to estimate how many people are actually present at an event and whether any of them fall into special categories (e.g. elderly, children, disabled). Moreover, passages can be blocked by objects and temporary construction sites can prevent people from using emergency exits.
The consultants from Siemens work together with the customers and their architects and planners to develop a variety of scenarios, for which they then use Crowd Control to calculate and visualize the resulting effects. Among other things, experts can take different types of people and blocked passages into account.
The algorithm, which was developed by Siemens' global research unit Corporate Technology, divides spaces into small virtual cells, each of which corresponds approximately to the space needed by a single human being. Force fields are used to define the behavior of empty and occupied cells.
Users can select person' starting points and destinations. Once the parameters are set, the model can run an emergency scenario that enables it to predict where dangerous situations would arise in the event of an evacuation under the postulated conditions.
Buildings can be made safer and before construction
Because the results can be viewed in 3D and in real time, the software can also be used as a training tool for demonstrating a variety of scenarios to security personnel. The consultants from Siemens also assist architects and security officers by using Crowd Control to analyze building plans. As a result, buildings can be made safer and more cost efficient before they are actually constructed.
Possible areas of application include airports, train stations, schools, shopping centers, and office buildings. In the case of airports and train stations in particular, simulations are the only feasible means of determining whether existing plans will be effective in an emergency. The experts from Siemens plan to further enhance Crowd Control in the future so that it can simulate other highly complex scenarios such as floods and explosions.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
