SUMO User Documentation

"Simulation of Urban MObility" (SUMO) is an open source, highly portable, microscopic and continuous traffic simulation package designed to handle large networks. It allows for intermodal simulation including pedestrians and comes with a large set of tools for scenario creation. It is mainly developed by employees of the Institute of Transportation Systems at the German Aerospace Center. SUMO is licensed under the EPL 2.0. The source code may also be made available under the following Secondary Licenses when the conditions for such availability set forth in the EPL 2.0 are satisfied: GPL2 or later.

Please use the mailing lists for sharing your results or for asking questions. Answers to some common questions may also be found in the FAQ.

Additional Tools#

In addition to the main applications (sumo, sumo-gui, netedit, netconvert, etc.), there are over 150 additional tools. They cover topics from traffic network analysis, demand generation, demand modification to output analysis. Most of them are written in python. All tools can be found in the SUMO-distribution under <SUMO_HOME>/tools.

For an index of all tools see:

Below are links to some of the most important/used tools:

  • osmWebWizard - create a simple scenario, in just a few clicks and using your web browser
  • Interfacing TraCI from Python - access a running SUMO simulation using Python
  • sumolib - Python modules for working with SUMO networks and sumo xml files in general
  • Xml Tools - tools for converting SUMO outputs to CSV/Spreadsheet, and vice versa
  • - export mobility traces (FCD output) into different "trace file" formats
  • - determine the differences between two networks
  • Visualization Tools - visualize a wide range of simulation outputs in a graphical and friendly way

Software Contributions#

Some people extended SUMO or built tools to make it more usable. Not all of these extensions are part of the "SUMO core".
