Installation Guide

This guide describes the steps needed in order to install and configure Eclipse MOSAIC on Debian (i.e. Ubuntu) distributions, Windows, and macOS. MOSAIC requires Java and SUMO to be installed; our analysis will be running on Python,

Installing Java

Open a terminal on your computer (Linux & Mac: search "terminal"; Windows: search "cmd").

To check if Java is already installed on your computer, type java --version. The output should look similar to this:

openjdk 18.0.1 2022-04-19
OpenJDK Runtime Environment Homebrew (build 18.0.1+0)
OpenJDK 64-Bit Server VM Homebrew (build 18.0.1+0, mixed mode, sharing)

If you get an error message or something similar, you probably need to install Java JDK:

Install on Linux

1. Download the latest LTS release
2. Create a new directory in your home-folder called adoptopenjdk
3. Copy/move the tarball from your download folder to adoptopenjdk and open a terminal in this folder
4. Extract the tarball using tar xzf OpenJDK17U-jdk_x64_linux_hotspot_17.0.3_7.tar.gz
5. The tarball should extract the following folder: jdk-17.0.3+7.
6. Open a new terminal and type in the following commands: First cd and then gedit .bashrc.
7. Insert the following line at the end: export PATH=/home/<USERNAME>/adoptopenjdk/jdk-17.0.3+7/bin:$PATH, save and exit. You can get your USERNAME using the command whoami in a terminal.

Install on Windows

1. Download the latest LTS release
2. Double click and run as administrator
3. IMPORANT: You need to set the environment variable JAVA_HOME. See next Figure:

Install on Mac

1. Download the latest LTS release
2. Install the .pkg file just like any other application
3. Open a new terminal and type java --version. It should now be installed.

Check if the installation was successful by typing java --version in a new terminal.

Installing SUMO

Install on Linux

In the terminal, type in the following commands:

sudo add-apt-repository ppa:sumo/stable
sudo apt-get update
sudo apt-get install sumo sumo-tools sumo-doc

Install on Windows

Download SUMO and install as usual.

IMPORTANT: Don't forget to set environment variable SUMO_HOME:

Install on Mac

For macOS you can follow the official guide. Note, that the XQuartz or sumo-gui dependencies are not required for this workshop.

• Install Homebrew, e.g. via /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
• Run brew update, brew tap dlr-ts/sumo and brew install sumo
  • The last command should output a path like export SUMO_HOME="/opt/homebrew/opt/sumo/share/sumo"
• From macOS Catalina (10.15) run open .zshrc, otherwise open ~/.bashrc (or whichever shell you are using)
  • If the above command fails (The file ... does not exist.) first run touch .zshrc/touch .zshrc and rerun
• Enter the command outputted by brew install sumo as a new line in this file.

Check if the installation was successful by typing sumo --version in a new terminal.

Installing Python

Make sure you have a working installation of Python 3.6 or newer by running python --version. If you don't, install it using your package manager of choice or the official website.

Check if the installation was successful by typing python --version in a new terminal.

Running the Workshop Material

Download this repository using either git or simply clicking Code -> Download ZIP on the GitHub website.

Within the repository directory, we now install the requirements for running the simulation in Jupyter lab:

python3 -m venv venv              # create venv
. venv/bin/activate               # activate venv
pip3 install -r requirements.txt  # install dependencies

You can now start Jupyter lab by running jupyter lab, which should open a new browser window/tab. Open mosaic.ipynb and sequentially run all cells.

Congrats! If all the notebook cells run without errors, you are ready to attend the practical session!
