If you are using the VCE container, you may skip these steps unless you made any changes and need to recompile. Make sure to run the commands for running a scenario from inside the container.


Since Veins is an OMNeT++ subproject, the network simulator OMNeT++ is an essential prerequisite. Follow the installation instructions for an up-to-date version (as of writing this, tested with OMNeT++ 6.0).


Once OMNeT++ is fully installed and the environment variables PATH and LD_LIBRARY_PATH are set accordingly, you are ready to install Veins. Download an up-to-date copy from the Veins website (as of writing this, tested with Veins 5.2) and extract the archive to your preferred installation directory. Then run the following commands in Bash:

source ./setenv

Use make -j8 to make use of multiple processing cores, if available (in this example, 8). As with OMNeT++, make sure to set up the environment variable PATH in your .bashrc or equivalent shell configuration files to include the bin/ directory of Veins.

Refer to the Veins tutorial for further installation details, especially w.r.t. dependencies, and on how to run a demo scenario.


Navigate to the veins-evi subfolder of your VCE repository. Then run the following:

./configure --veins <veins_path, .e.g, ~/veins/veins-5.2/>

Running a VCE Scenario with V2X#


The 3D Environment can show a minimap on the handlebar of the virtual bicycle. If the ego vehicle receives context awareness messages (CAMs) from cars around it, the position of these cars at the time of transmission can be visualized. This works with any scenario, but let us stick with paderborn-north in this example.

First, build the street network for paderborn-north as described in 3D Environment (3DEnv). Make sure to select miniMap for the tablet application on the handlebar.

Next, start by launching the MiniMap example in veins-evi. In order to do so, navigate to veins-evi/examples/minimap/ and run the following:

./run -u Cmdenv -c LanradioDisabled

Then launch the EVI by running the following in the evi/ subfolder of your VCE repository:

poetry shell
cd networks/paderborn-north
../../scripts/ --config-file paderborn-north.evi.ini --sumo-binary sumo-gui --veins-host localhost --veins-port 12347

Finally, start the 3D Environment. Once the first other vehicles start arriving in the region of the ego vehicle, you should see indicator arrows on the MiniMap that will fade out over time, as shown in Fig. 2.
