Escape route steering of the next generation

Escape route steering of the next generation

The Federal Ministry of Education and Research (BMBF) supports the project SPIDER (Security System for Public Institutions in Disastrous Emergency ScenaRios) within the framework of the program "Research for Civil Security". The project is part of the scenario-oriented security research in the field of "protection and rescue of people". Complex crisis scenarios and major loss events are the focus here.

The IMS and the University of Duisburg-Essen are participating in the project led by the German Red Cross. The Chair of Physics of Transport and Traffic at the University of Duisburg-Essen is under the direction of Prof. Dr. med. Michael Schreckenberg with the simulation of passenger flows and road traffic. The focus of SPIDER is on uniform communication concepts for the information systems of rescue organizations involved in the major loss event. The goal is networking and thus an exchange of information between the fire brigade, police, the German Red Cross, and other aid organizations. A focal point of the project is a fully automatic, adaptive escape route guidance system, which intuitively guides escapees a safe way into the open air. Typical application scenarios include airport evacuation, trade fairs, event halls, stadiums or train stations.

What is special about this escape route system?

It is dynamic and can independently and continuously adapt to the damage situation in the hazardous area. The clou lies in the way in which the necessary dynamics come about. With the help of a passenger flow simulation possible danger points can be identified during the evacuation and optimized escape routes can be determined. In this case, in an online mode, data from the building technology is constantly being used to check the current situation and react in real time.

The simulation results are then transferred to the escape route system for displaying the best possible escape routes. The IMS supplies necessary data for the simulation and implements the control logic of the escape route pictograms, which processes the simulation result. The automated safety and emergency lighting is supplied by the medium-sized system house INOTEC Sicherheitstechnik GmbH. In close coordination with IMS, the entire signage in the property is controlled fully automatically and thus represents another innovation. "By simulating the flow of people as part of an evacuation, potential hazards can be identified at an early stage. Thanks to the dynamic escape route guidance, we can react to the threats and refute them ", says Prof. Dr. med. Schreckenberg.

In order for the simulation to represent reality as well as possible, it has to be supplied with a wealth of information. Since the concept is intended to be applicable to any type of real estate, IMS and the University of Duisburg-Essen have recorded a large amount of usable information and provided it for further processing by the simulation module. Marcel Kunzmann, Project Manager of IMS: "The goal of SPIDER is an open and independent system, which should work in every property under different conditions. For this reason, we have also defined general concepts and open standards for the simulation. "In the field of building technology, data are taken over from safety-related facilities such as fire alarm systems. In addition, people counting systems can make a lasting contribution by providing up-to-date information on the total number and distribution of people in the property.

"The main challenge in this project is to integrate the provided data from the building services engineering into the modeling of the evacuation process and to process it online in the simulation", adds Prof. Dr. med. Add Schreckenberg.

Ideally, the adaptive escape route guidance system refers to the entire area of a property if, for example, all existing halls have to be evacuated on a fairground. Then it is necessary to guide people safely and on a short way to the assembly points. Currently, the research work is in full swing at all involved chairs and companies. In October 2011, the results of the research will be presented in a practical demonstration on the grounds of Koelnmesse.

In addition to the IMS and the University of Duisburg-Essen are involved in the research project:

German Red Cross, Police NRW, Fire Brigade Gelsenkirchen, Catholic Hospital Bochum, Koelnmesse GmbH, PRO DV Software AG, CKS Systems GmbH & Co. KG, Chair of Communication Networks TU Dortmund, Institute of Psychology & Emergency Psychology TU Dortmund

Great. Thank you very much!

Maybe you want to follow us on ...

We are sorry that you did not like this post so much.

How can we improve that?
