Description
Before you change the signal timing at a busy junction, you would like to know if it makes the jam worse, and you cannot test that on a real road. SUMO is an open-source microscopic traffic simulator from the German Aerospace Center that lets you load a road network, vehicles and traffic lights and simulate every vehicle individually.
Its graphical window opens network files directly, starts and pauses a run with one click, and can plot the live speed curve of any vehicle you pick. It suits coursework, algorithm validation and signal timing comparisons, with no license to apply for.
Network view: Open network and simulation files to watch junctions, lanes and vehicles in motion, colour lanes by type, and locate junctions, traffic lights and points of interest.
Per-vehicle simulation: Each vehicle is modelled on its own, with counters for departed, running and arrived vehicles plus collisions and teleports, and adjustable step and delay.
Lane permissions: Choose which vehicle classes may use a lane, such as passenger cars, motorcycles, emergency vehicles or buses.
Live graphs: Select a vehicle to pop up a curve of its speed and other values, handy for finding out why one car suddenly slowed.
Companion tools: The suite also ships tools such as the netedit network editor and can build networks from OpenStreetMap data.
