Modeling the Interactions of Pedestrians
When pedestrians are moving in a crowd they interact with each other. In order to simulate these intaractions models need to be developed.
Our research is guided by the following research question: How can we understand the properties of a crowd and predict its dynamics in closed and open spaces?
This question is addressed through a research design that weaves together three streams: development of operative models, investigation of route choice models, and software engineering. In this way, our division aims for interdisciplinary research.
In the long-term different products for prediction and evaluation of crowds dynamics are to be developed based on different open-source projects to guarantee sustainability and continuation of development. In this regard, our research is centered around the development of JuPedSim, an open-source software mainly developed by researchers from our division. It will serve as starting platform for investigating new scientific questions related to modeling of pedestrian dynamics as well as developing new solutions for real-time assessment and visualization of crowd densities in buildings and open spaces.
Our research is used in different ways. First, bachelor, master, and Ph.D. students are provided with numerical frameworks to focus on research, i.e. development and validation of new models. Their research results are not only published in written form but will be made public in the form of software pieces integrated into the offered framework. In this manner, we can guarantee continuity of research and strengthen the reproducibility of scientific results even after the end of the supervised theses.
Second, we aim to bundle our theoretical findings in form of a real-time assessment and prediction tool that can be used in different applied projects to gain instant insights on the dynamics of the crowd and hence preventively avoid potentially dangerous situations e.g. high densities as well as temporal and spatial bottlenecks.
The research of our division aims at exploring several interrelated topics that fall under "mathematical modeling of pedestrian dynamics". These topics are:
