jupedsim-network

A coarse network egress model for fast estimates of evacuation times (pre-movement plus movement). Rooms, corridors and stair flights are nodes with an area; doors and stair entries are links with a flow capacity. Agents move through the graph by relations adapted from the SFPE hydraulic model. A run of a ten-storey building takes about 0.1 s, so scenarios can be sampled many times.

The package is a companion to JuPedSim: use the network model to screen scenarios and find critical cases, and the microscopic models of JuPedSim to check geometry details. It depends only on NumPy.

The model is a prototype. It is verified against hand calculations but not validated against experiments, and it is not intended for regulatory or design use; see the limitations.

Install

Python 3.10 or later:

pip install jupedsim-network

Development

uv sync
uv run pytest
uv run ruff check . && uv run ruff format --check .

The documentation is a Hugo site with the Hextra theme in site/. Hugo (extended) and Go are needed to build it:

uv run --group docs python scripts/figures/make_figures.py
uv run --group docs python scripts/figures/make_gifs.py
cd site && hugo server

The figures and animations are not stored in git. The two scripts write them to site/static/images/network/ (a few minutes); CI runs them before every build.
