SUMO (Simulation of Urban Mobility) is an open-source traffic simulator. The .net.xml format describes road networks with lanes, junctions, and connections. Used for traffic modeling, signal optimization, and transportation planning.
Key Features

About SUMO Format
SUMO is an open traffic simulator that models every car separately. People use it to see what happens to a district if a street is closed, a lane is added or the traffic light phases are changed. The road network is described by an XML file: street edges, junction nodes, lanes and the connections between them.
Usually the network is obtained from OpenStreetMap with a separate utility, and that means fiddling with settings and cleaning the data. Our export hands you a ready network for the chosen area right away — convenient for a study assignment, a quick test of a hypothesis or a demonstration.
What is in the archive: the road network file and a configuration that is enough to launch a simulation. The streets are taken from OSM together with the road type, the number of lanes (up to eight) and the permitted speed by class; the coordinates are converted from latitude and longitude into local meters.
What the network does not have: traffic light programs and travel demand. Traffic light logic is set in SUMO separately, and vehicle routes are generated with the standard utilities — without them the simulation will start, but nobody will drive down the streets.
What Program Opens SUMO Files
The following programs and applications can open, edit, and work with SUMO Network (.zip) files exported from OSM2CDR:
Format specifications
- Open standard
- 2D only
- Lossless (no quality loss)
- Stores feature attributes
- Output: 2 files in archive
- Eclipse SUMO traffic-simulation network XML (ZIP with network.net.xml + simulation.sumocfg). Ready to open in SUMO-GUI.

How to Export SUMO
How to Open After Export
- Eclipse SUMO (free) — unpack the archive and open the configuration in sumo-gui: the network will be drawn, and from there the simulation starts with a button.
- netedit — the network editor from the SUMO package: fix junction geometry, add a lane, assign a traffic light.
- Travel demand — generate routes with the randomTrips or duarouter utilities and connect the route file in the configuration, otherwise the streets will stay empty.
- TraCI (Python) — control the simulation from a script: collect statistics, change phases on the fly, embed SUMO into your own experiment.
- netconvert — if junction geometry looks odd, the network can be rebuilt and checked with this utility from the SUMO package.
