About Eclipse SUMO

Eclipse SUMO is a free and open source traffic simulation suite. It is available since 2001 and allows modelling of intermodal traffic systems - including road vehicles, public transport and pedestrians. Included with SUMO is a wealth of supporting tools which automate core tasks for the creation, the execution and evaluation of traffic simulations, such as network import, route calculations, visualization and emission calculation. SUMO can be enhanced with custom models and provides various APIs to remotely control the simulation.

Application Areas

SUMO has been used within several projects for answering a large variety of research questions:

  • Evaluate the performance of traffic lights, including the evaluation of modern algorithms up to the evaluation of weekly timing plans.
  • Vehicle route choice has been investigated, including the development of new methods, the evaluation of eco-aware routing based on pollutant emission, and investigations on network-wide influences of autonomous route choice.
  • SUMO was used to provide traffic forecasts for authorities of the City of Cologne during the Pope’s visit in 2005 and during the Soccer World Cup 2006.
  • SUMO was used to support simulated in-vehicle telephony behavior for evaluating the performance of GSM-based traffic surveillance.
  • SUMO is widely used by the V2X community for both, providing realistic vehicle traces, and for evaluating applications in an on-line loop with a network simulator.
  • AI training of traffic light plans.
  • Simulation of the traffic effects of autonomous vehicles and platoons.
  • Simulation and validation of autonomous driving function in cooperation with other simulators.
  • Simulation of parking traffic.
  • Simulation of railway traffic for AI-based dispatching of vehicles.
  • Traffic safety and risk analysis.
  • Calculation of emissions (noise and pollutants).


The SUMO package contains the following applications:
