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.

How to disable lane changes in SuMO?

I am using a TraCI call to set the lane change mode of a vehicle to 0 to disable all lane changing: TraCICommandInterface::setLaneChangeMode(0b000000000000); However, the vehicle still does a lane change afterwards. I also tried 256 (i.e.…

How to begin a veins simulation at t > 0

I am working on veins simulation with LuST scenario. My goal is to choose a time period and begin my veins simulation at a certain moment, e.g. 6:00, of LuST. In SUMO, parameter "begin" can be modified so it's easy to set traffic flow. So I think it…
