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 add more cars into simulation, limit speed and edit traffic lights

I want to add more vehicles and change the speed. I used the command --max-num-vehicles 30 to try and start the simulation with more cars but for some reason the run time simulation never passes 50 or 60 active cars. Also my simulation has traffic…

Converting X & Y to Lat & Lon

I'm currently working on a school project where we have to set up a traffic simulation. We decided to use TraaS. TraaS has a method to retrieve the current X and Y coordinates of a given vehicle (see getPosition). However these X and Y coordinates…

Is it possible to change the timestep of SUMO output?

I am using SUMO to generate a network from openstreetmaps. I am interested on observing my results of vehicle positions in smaller timestep than 1 second, but for example 0.5 second. Is it possible to do this change?
