OpenStreetMap (OSM) is a free, open-source, editable map website that can provide free download. osm2gmns, as a data conversion tool, can directly convert the OSM map data to node and link network files in GMNS format. Users can convert and model drivable, walkable, railway, or aeroway networks with a single line of Python code.
pip install osm2gmns
If you meet installation issues, please refer to the user guide for solutions.
Get network from osm file and conduct intersection consolidation
>>> import osm2gmns as og
>>> net = og.getNetFromOSMFile('map.osm')

You can visualize generated networks using NeXTA or QGis.
