Public sports events, cultural or folk festivals attract large crowds in cities. Examples include the Cannstatter Wasen in Stuttgart, the Hafengeburtstag in Hamburg or fan miles during European or World Cup soccer matches in Berlin. Sometimes such events also take place in close proximity to each other, which further increases the number of people. Due to the high number of people, dangerous situations can arise that can severely affect the safety of visitors. If such areas have to be evacuated due to acute danger situations (e.g. terrorist attacks, storms), the streams of visitors can collide in an emergency.
The Fraunhofer SIRIOS competence center has specialized in this problem as one of its main research areas. SIRIOS solutions enable the emergency services involved, such as the police, fire department, and private security companies, as well as event organizers, to provide valuable information using video analysis and situational awareness to support the security of events. In addition, important parameters of crowds and access barriers can be recorded and used for advanced simulations to prevent dangerous situations in the planning phase.
Video exploitation
Fraunhofer SIRIOS works with conventional and widespread sensor technology as well as image and video analysis in conjunction with artificial intelligence on assistance systems for authorities and organizations with security tasks (BOS) and event organizers. The focus here is on extracting key crowd data, such as the total volume, the distribution of people, the identification of bottlenecks and traffic jams, and the detection of conspicuous movement behavior in crowds. These technologies enable more precise monitoring and planning of large events and help to increase safety.

Physical protection
Fraunhofer SIRIOS deals with the simulative design and dimensioning of physical access protection for events. Numerical simulations can depict an impact scenario with sufficient accuracy and thus offer the possibility of predicting the penetration depth of the vehicle into the area to be protected for a large parameter space. With a visualization of the danger zones directly in a digital situation display, it helps security authorities and event safety representatives to create safety concepts for major events and public places.

Situational awareness (VR)
The Digital Map Table in Virtual Reality offers the opportunity to experience geodata in three dimensions through stereoscopic display. In addition to viewing the data on the virtual table, the pedestrian mode allows complete immersion in the virtual world and makes it possible to stand in the middle of a road junction or fly onto the roof of a high-rise building. No matter where the users are in the world, in virtual reality, they can stand together at the same map table and plan and analyze the situation together, using all the functions also available in the web interface.
Digital MAP Table
Through the SIRIOS network, Fraunhofer maintains close contact with the authorities and organizations with security tasks (BOS) in order to be able to react quickly to current capability gaps and requirements. In addition to existing software solutions, which are also developed in collaboration with industry partners, there is also the possibility of incorporating Fraunhofer technologies into the operations of the police and other BOS in a targeted manner. This is done through joint research and development projects in which customized solutions are developed.
The exhibits of Fraunhofer SIRIOS can be found in hall 2, booth number: J25.
