Since the year 2000, the Centre of Apllied Informatics and the Institute für Transport Research at the German Aerospace Centre devops a microscopic road traffic simulation package named "SUMO" - an acronym for "Simulation of Urban MObility". Meanwhile, the simulation is capable to deal with realistic scenarios such as large cities and is used for these purposes within the Institute´s projects. The idea was to support the traffic research community with a common platform to test new ideas and models without the need to reimplement a framework that handles road data, vehicle routes, traffic light steering etc. To achieve this goal, the simulation code is available as open source. Within this publication, we would like to demonstrate how most attributes of traffic flow can be simulated. This should be mainly intersting for educational purposes
