NaMIx

NaMIx ("Sustainable mobility index to assess the location-related mobility potential", in German: "Nachhaltige-Mobilität-Index zur Bewertung des standortbezogenen Mobilitätspotentials") is a project that aims to develop an index for sustainable mobility at locations and for neighborhoods that incorporates existing data and indices and maps different spatial levels. You can find out more about the project here: https://verkehrsforschung.dlr.de/de/projekte/namix.

Most of the needed data can be retrieved from OpenStreetMap (OSM). Public transport stops can be obtained from OpenStreetMap (OSM) or General Transit Feed Specification (GTFS).

Please note that due to restrictions regarding the distribution of some of the used datatypes, we had to limit the functionality in comparison to what has been shown during the final project presentation. Given the current version, the locations of buildings are retrieved from OSM instead of using the BKG address dataset. In addition, schools are retrieved from OSM as well and instead of using access by foot to elementary schools and access by bike to secondary schools NaMIx version 0.2.0 computes the access to all schools obtained from OSM by walk and by bike.

Installation

The current version is "NaMIx-0.2.0". It computes ten indicators almost (see above) as presented at the final project presentation.

Please note that current NaMIx is realised as a Jupyter Notebook and that it is currently available in German only.

To run the computation, please do the following

• Download a version of NaMIx : You may download a copy or fork the code at NaMIx' github page. : Besides, you may download the current release here:
  • NaMIx-0.2.0.zip
  • NaMIx-0.2.0.tar.gz
• Depack the obtained file into a folder of your choice (named <NaMIx> from now on)
• Open the command line in this folder
• Optionally create a virtual python environment (recommended)
  • run python -m venv venv_namix
  • run venv_namix\Scripts\activate.bat
• Run pip install -r requirements.txt to install all necessary dependencies
• Download the 0.6.0 version of UrMoAC from UrMoAC-0.6.0.zip. Extract the contents into <NaMIx>/demo/tools so that the jar file is located directly within this folder.
• Download GTFS data (e.g. from MVG). Extract the contents so that can be found in <NaMIx>/demo/input/GTFS.
• Start the jupyter notebook
  • You should have a command line open in <NaMIx>
  • Run python -m jupyter notebook
  • open "namix_demo.ipynb" in the notebook

The notebook processes the input data, computes the individual indicators and the joined NaMIx indicator, and stores the result in a geopackage file named "<NaMIx>/demo/namix.gpkg".
