Open source framework for simulating, analyzing and visualizing pedestrian dynamics.

This software is platform independent, released under the LGPL license and is written in C++ and Python.


The primary goal of JuPedSim is to provide students and researchers with a framework to investigate pedestrian dynamics and focus on research, i.e. development and validation of new models or model features, analysis of experiments and proper visualization of results.

JuPedSim is currently focusing on evacuation, but is easily extendable to cover other areas e.g. passengers exchange, commuter traffic in railway stations etc.

Organization of the code

JuPedSim consists of four loosly coupled modules, that can be used independently. These are:

  1. jpscore: the core module computing the trajectories.
  2. jpsreport: a tool for analyzing the trajectories and validating the model.
  3. jpsvis: a tool for visualizing the input (geometry) and output (trajectories) data.
  4. jpseditor: a tool for creating and editing geometry files with dxf import/export capabilities.
