JuPedSim: an open framework for simulating and analyzing the dynamics of pedestrians

There is a wide range of simulation software used to investigate pedestrian dynamics. It is paramountfor researchers to know exactly what the models are performing as this provides a better interpretationof the results. In this paper we introduce JuPedSim, the Jülich Pedestrian Simulator. JuPedSimis an extensible framework for simulating and analyzing pedestrians’ motion at a microscopic level.It consists at the moment of four modules which are loosely coupled and can be used independently.The first module simulates the movement of pedestrians given a geometry and an initial configuration.The second module visualizes the geometry and the trajectories. High resolution videos canalso be recorded directly from the module interface. The third module analyses the results fromthe simulation or any other source, for instance experiments, and generates different type of plotssuch as densities, velocities and flows. The last module is a geometry editor to prepare the neededenvironment and input files for the simulation and the analysis
