SUMO is an open-source microscopic continuous traffic flow simulation software developed by the German National Aerospace Center. It comes with a traffic simulation road network editor, which can add roads through interactive editing, edit the connection relationship of lanes, process intersection areas, edit signal light timing, etc. It is also possible to convert road networks from Vissim, OpenStreetMap, OpenDrive via a separate conversion program. The route for each vehicle can be specified by editing the route file, or randomly generated using parameters. During operation, it can handle the continuous traffic simulation requirements of several square kilometers and tens of thousands of vehicles at the same time, and also provides an OpenGL-based visualization terminal to display the results of traffic simulation in real time.
