JuPedSim

JuPedSim is an open-source library for simulating the dynamics of pedestrians and crowds. It models how individual agents move through a walkable geometry, react to one another, and route toward exits, making it suitable for studying evacuations, crowd management, and the design of buildings, transport hubs, and public spaces.

Features

• Python-first API over a high-performance C++ core — set up geometries,
  spawn agents, define routes, and step the simulation entirely from Python.

• Multiple operational models, including the Social Force Model.

• Flexible routing via journeys and stages (waypoints, exits, waiting
  areas) with support for probabilistic and conditional transitions, so agents
  can follow alternative paths through the same geometry.

• Comes with a web-based frontend https://app.jupedsim.org

  Use cases

  Evacuation-time studies, route-choice and bottleneck analysis, capacity
  planning, and reproducible research in pedestrian dynamics.
