There is a Plugin for JOSM, the OpenStreetMap editor, which allows converting OSM data to MATSim.

You can also use it to edit a MATSim network file directly.

You can download and use it directly from JOSM, which you can launch directly from the Web. Go to Preferences -> Plugins, and look for "matsim".

Please see the manual for details, but note that you do not need to follow the special installation instructions anymore. We are now hosted on the JOSM plug-in repository.

Development is on GitHub.

Please report any bugs, questions, issues etc. directly to for better support.
