This video shows two contributions of PTV AG to the HERMES research project.

The HERMES research project intends to build an evacuation assistant for arenas. It is funded by the German Ministry for Research (BMBF), headed by the Jülich Research Center and includes the following partners: Forschungszentrum Jülich GmbH Supercomputing Center, Bergische Universität Wuppertal Abteilung Bauingenieurwesen, Imtech Deutschland GmbH & Co. KG, Multifunktionsarena Immobiliengesellschaft mbH & Co. KG (ESPRIT arena), PTV Planung Transport Verkehr AG, TraffGo HT GmbH, Universität Bonn Geographisches Institut, Universität zu Köln Institut für Theoretische Physik, Vitracom AG, Feuerwehr Düsseldorf, Polizeipräsidium Düsseldorf, Landesamt für Zentrale Polizeiliche Dienste NRW, and Special Security Service SSSD GmbH.

The HERMES project page can be found here: http://www.fz-juelich.de/jsc/hermes

Part of the project are extensive experiments (carried out by the Universities of Cologne and Wuppertal and the research center Jülich) on pedestrian dynamics of which video footage can be found here on youtube:4AZQ4lFLcb4, J4J__lOOV2E, and CBaqSUWz56M
PTV AG supports this research and utilizes the results for calibration of the pedestrian simulation model.

Now for what can be seen in the video on this page. The first part (starting at 0:07) shows a VISWALK simulation of the evacuation of the part of the stadium (the Esprit arena in Düsseldorf) which is in focus of the research project. Microscopic simulations of pedestrian dynamics are part of the evacuation assistant to allow the stadium control as well as the rescue forces a glimpse into how the distribution of occupants can be expected to develop within the next few minutes. Such an online simulation obviously sets a high requirement to the computation speed of a model. This is the field of the experts of the Supercomputing Center of Jülich where one of the fastest computers of the world is at home. In the video the visitors are simulated to leave their place on the grandstands, walk through the gates and down to the floor level of the arena to then leave it at the areas marked with bright green. The grandstand areas are shown in a lighter grey and so are its walls compared to the coloring of the floor level. The four blue areas mark where the remaining part of the arena continues, which are not investigated in the project.

The second part (starting at 3:07) of the video shows the result of a VISUM calculation. It shows the visitor flows if all doors and corridors are available. Different to the microscopic simulation with VISSIM the idea is not to compute how the situation is expected to, but to compute what -- hypothetically -- would be an optimal distribution of occupants on exits. This is especially interesting in case that a corridor is blocked and those who normally would use it would be needed to be distributed on other exits. While it is a hypothetical result as the staff guiding the occupants can never be able to exactly implement the result, it nevertheless is helpful to show tendencies, and a big advantage is that such a microscopic computation with VISUM is much faster than any microscopic model can ever be. Furthermore it allows a better understanding of the whole infrastructure with the processes by doing "what if...?" case studies.

The third part (starting at 3:47) shows how these and more results (e.g. of smoke detectors) are displayed all in one graphical user interface -- a communication module. This is the "face" of the evacuation assistant system as it is shown to the heads of the rescue forces and the arena management.
