Welcome to eFlow!

The aim of the project is to develop a software tool that can be used to simulate the crowd dynamics and motion of people in rooms and at the same time the associated probability of infection.

Users can check different room designs for occurrences of high crowd densities or infection rates. The prototype of the software tool shall contain one or two integrated settings, such as an arbitrary evacuation scenario (e.g. fans leaving a football stadium or students leaving seminar rooms and lecture halls of a university building at lunchtime).
The simulation of a special scenario can be controlled with the help of various parameters: number of people, average speed, proportion of people who are likely to be ill, key figures of the infectious disease such as infection rate, type of transmission, size of the infection area, etc. As a result, the simulation provides the statistically estimated number of new infections under these conditions during a certain period of time and a simulation of the spread of the contagion. As an effect, it can then be determined in which areas of the room the risk of infection is greatest and what maximum number of people in a room should not be exceeded. Room designs can be optimized in this sense; either to ensure more security for people, or to grant more freedom with the same security. In the medium term, the health authorities can be given a tool to check hygiene concepts or planned visitor numbers for companies and events.
