Questions tagged [sumo]

SUMO (Simulation of Urban MObility) is a microscopic traffic simulation package. This tag should be used when you have a question about software development with SUMO package.

SUMO is a free and open traffic simulation suite which is available since 2001. SUMO allows modelling of intermodal traffic systems including road vehicles, public transport and pedestrians. Included with SUMO is a wealth of supporting tools which handle tasks such as route finding, visualization, network import and emission calculation. SUMO can be enhanced with custom models and provides various APIs to remotely control the simulation.

See the contact page for support resources.

The core applications are written in C++ while the script tooling around it is in Python. Clients for external interfacing over the Traffic Control Interface (TraCI) protocol are available in Python, Java, C++ and MATLAB.
