Monitoring system to mass panic in the stadium
Jülich scientists have unveiled this past weekend along with several project partners in the Esprit Duesseldorf Arena is a pedestrian-control system that beats in time with the threat of mass panic alarm and aims to provide alternative escape routes.
The so-called Hermes evacuation assistant captured the crowds with special 3D cameras. The data is then passed to a pedestrian simulation that calculates a short-term prognosis of the Crowd. The system can simulate tens of thousands of visitors walking distances up to 15 minutes in advance and the security forces early warning of the emergence of 'dangerously high densities of people. " In addition, it is associated with the risk management system of the stadium. This can result in the event of an impending eviction, such as a fire escape route to determine the best for the audience.
As part of the project to special 3D cameras have been developed that are barely larger than a webcam. You register each visitor who passes through the inputs and outputs. For privacy reasons, they only store, according to the Hermes consortium "only counts and no images." In order to detect the distribution of individuals in the test region of the Esprit Arena around 100 cameras were installed in an area of the auditorium. Based on these data, a software simulated on a specially decorated for the Hermes project parallel computer with 208 processors, the further course of the person distribution. As a theoretical basis for the pedestrian simulation, the scientists use models adapted from statistical physics. To vote on these models the behavior of pedestrians in the project were more than 200 experiments conducted with some up to 400 participants.
According to Hans-Joachim Kensbock-Rieso, chief police in Dusseldorf Stadium could provide the out of the Hermes project emerged assistance system in critical situations really important, additional notes: "With the aid of such assistants, the forces can always keep track of how many people are reside in their respective areas. " The software supports decision-makers in crisis situations in the analysis of various strategies to "escape exits", because the shortest route is not always necessarily the best. Sometimes, groups must first be directed away from nearby outlets to avoid overloading of individual sections later.
