Description Complete dataset of all 29,850 USA cities Roads network as a graph in the shp format. The extracts follow 2016 official USA cities boundaries.
Graph are identified by their [city_code].shp. Cities code are provided by the Tiger Census Dataset.
Graph have been created by
  1. extracting all openstreetmap.org (osm) maps for each USA City
  2. extracting the graph from osm extract using the policosm python github library
  3. simplifying the graph by removing all degree two nodes to retain only a workable transportation network. Original road length is retained as an attribute


  • Nodes includes latitude and longitude attributes from WGS84 projection

  • Edges includes length in meter (precision < 1m), tag:highway value from osm
