Questions tagged [sumo]

This tag applies to everything around the microscopic traffic simulation SUMO. This includes network conversion, routing problems and external interfacing especially using TraCI. It is also connected to tags like veins, simulation and routing.

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.

The main support channel for the SUMO community is the mailing list sumo-user@lists.sf.net.

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