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.

Why does the FINISH function run multiple times (in veins)?

I know in veins the FINISH function is done when the car comes out of the simulation. In My simulation, the car travel time is calculated.This parameter is stored in a file when the cars exit the simulation by the FINISH function. But when I check…

Pedestrian Simulation in veins (omnet++/sumo)

I'm trying to run a pedestrian simulation from sumo in omnet++. To keep it easy (i am a beginner) I decided to use the Erlangen example provided with veins and extend it with a couple of pedestrians. I added the pedestrians in sumo and ran it. It…

How to check for an internal edge via TraCI?

I am trying to figure out whether an edge/lane is internal. When SuMO creates internal edges/lanes, it prefixes them with a colon [1]. Currently, I am exploiting this information, however, it seems that you also can annotate arbitrary other edges as…

Different output using SUMO only versus using SUMO, Veins, and OMNeT++ together

In my project, I am trying to make a base case, in which the market penetration is 0.0. In another word, no vehicle is using the application. I tried two ways to do this. First, I use SUMO only to run the simulation, and secondly I use SUMO, Veins…

How to enable SUMO TraCI using SimuLTE and Veins?

I am using SimuLTE and Veins simulating sending safety message via LTE. The content of the message depends on the real-time values of the traffic, e.g., mean speed. In order to get such values, I plan to use TraCICommandInterface supported by Veins.…
