Notes
| Each state-level zip file contains the files (shapefiles, node/edge lists, or GraphML files) of the street networks in that state (at the scale of city/town, urbanized area, county, census tract, or Zillow-defined neighborhood). The files are named like FIPS_code-state_abbreviation-spatial_scale-street_networks-file_type.zip
You can use the search box to filter files for downloading if you only want a certain state or file type or spatial scale.
Urbanized area boundaries come from the 2017 TIGER/Line shapefile of U.S. census bureau urban areas. City and town boundaries come from the 2017 TIGER/Line shapefiles of U.S. census bureau places for all 50 states plus DC. County boundaries come from the 2017 TIGER/Line shapefile of U.S. counties. Census tract boundaries come from the 2017 TIGER/Line shapefiles of U.S. census bureau tracts. Neighborhood boundaries come from the 2017 Zillow neighborhood boundary shapefiles. Each street network was downloaded from OpenStreetMap using OSMnx v0.8.1 and its graph_from_polygon function, passing the parameters network_type="drive" (to download all public, drivable streets) and retain_all=True (to retain all connected components if the graph is disconnected due to discontiguous geography). The networks were then saved as shapefiles, node/edge lists (CSV format), and GraphML files. These GraphML files can be directly reloaded and analyzed with OSMnx.
