osm2gmns is an open-source Python package that enables users to conveniently obtain and manipulate any networks from OpenStreetMap (OSM). With a single line of Python code, users can obtain and model drivable, bikeable, walkable, railway, and aeroway networks for any region in the world and output networks to CSV files in GMNS format for seamless data sharing and research collaboration. osm2gmns mainly focuses on providing researchers and practitioners with flexible, standard and ready-to-use multi-modal transportation networks, as well as a bunch of customized and practical functions to facilitate various research and applications on traffic modeling.

.. code-block:: bash
pip install osm2gmns
If you meet installation issues, please refer to the user's guide
_ for solutions.
You can find the osm map file used in the examples below at 'sample networks/Arizona State University, Tempe Campus'
Quickly get the network with point of interest (POI) information from an osm file
.. code:: python
>>> import osm2gmns as og
>>> net = og.getNetFromFile('asu.osm', POI=True)
>>> og.outputNetToCSV(net)
Generate multi-resolution networks from an osm file
.. code:: python
>>> import osm2gmns as og
>>> net = og.getNetFromFile('asu.osm')
>>> og.consolidateComplexIntersections(net, auto_identify=True)
>>> og.buildMultiResolutionNets(net)
>>> og.outputNetToCSV(net)
You can use the following code to get the relation id of a place of interest and download the corresponding osm file.
.. code:: python
>>> import osm2gmns as og
# get relation id of a place of interest
# For the place of interest, e.g. Arizona State University
# e.g. "Tempe, Arizona, United States"
# e.g. "Arizona, US"
# e.g. "Beijing Jiaotong University, Beijing, China"
>>> rel_id = og.getOSMRelationID('Arizona State University')
>>> rel_id
Info: Found relation id 3444656 from web
Info: location of the place of interest:
