7. Traffic Simulation with SUMO – Simulation of Urban Mobility

SUMO is a microscopic road traffic simulation made available as open source under the GPL license. The complete suite includes tools for importing road networks, generating routes from different sources, and two versions of the traffic simulation itself, one started from the command line and one including a graphical user interface. The simulation uses the microscopic, space-continuous and time-discrete car-following model developed by S. Krauß and a lane-changing model developed within the work on the simulation. Traffic assignment is normally performed using the iterative approach formulated by C. Gawron, but further methods, such as a one-shot assignment method, exists. The traffic simulation offers a socket-based interface to external applications, allowing to interact with a running simulation online. Values and states of objects the simulation consists of can be both retrieved and changed. SUMO has been used within different projects both by the DLR and by external organizations.
