us_roads — United States roads (2000, 2008–2026)

Description

Road networks of the 50 U.S. states and the District of Columbia, derived from the TIGER/Line files of the U.S. Census Bureau for the 2000 Census. The data were prepared by D. Schultes for the 9th DIMACS Implementation Challenge on shortest paths. Nodes are road intersections and endpoints, and undirected edges are road segments between them. There is one network for each state (named by its two-letter postal code, e.g. CA), and the network merged combines all states into a single network, as produced by the merging program distributed with the data.

The networks have the following properties:

  • (Node) la, lo: the latitude and longitude of the node, in degrees.
  • (Edge) distance, travel_time: the length of the road segment and the estimated travel time along it, both as given in the DIMACS files (the units are not documented there).
  • (Edge) road_category: the road category, given by the numerical part of the TIGER census feature class code (CFCC) of the road (e.g. 11–18 for primary highways with limited access, 21–28 for primary roads without limited access, 31–38 for secondary and connecting roads, and 41–48 for local, neighborhood and rural roads).

The networks tiger_2008 to tiger_2026 are the national road networks of the annual releases of the TIGER/Line Shapefiles of the Census Bureau, from the first one (2008) to the latest one (2026), one network per release, built directly from their "All Lines" (EDGES) files, one per county (about 3,235). These files contain all the linear features of the TIGER database (roads, railroads, hydrography, boundaries, ...) as topological edges between nodes (TNIDF and TNIDT), with the same node ids across counties; only the road edges (those flagged as roads, with MAF/TIGER feature class codes S1100 to S1830) are included, and an edge is a road segment between two nodes (intersections, ends of roads, and points where the road crosses other linear features, e.g. boundaries or streams). The networks are undirected and cover the 50 states, the District of Columbia, Puerto Rico and the Island Areas; they have parallel edges and self-loops (e.g. roads forming loops). Not included are the house number ranges of the edges, their geometries, and the railroads and hydrography of the EDGES files. These networks have the following properties:

  • (Node) tnid: the TIGER node id.
  • (Node) la and lo: the latitude and longitude of the node (NAD83, in degrees).
  • (Edge) tlid: the permanent TIGER/Line id of the edge.
  • (Edge) name: the full name of the road (e.g. Ingomar St NW; empty if unnamed).
  • (Edge) mtfcc: the MAF/TIGER feature class code (e.g. S1100 primary road, S1200 secondary road, S1400 local neighborhood road, rural road or city street, S1500 vehicular trail, S1630 ramp, S1640 service drive, S1710 walkway, S1720 stairway, S1730 alley, S1740 private road, S1750 internal census use, S1780 parking lot road, S1820 bike path or trail).
  • (Edge) county: the FIPS code of the state and county.
  • (Edge) zip_left, zip_right: the ZIP codes on the two sides of the road.
  • (Edge) length: the length of the edge along its geometry (km).
  • (Edge) decked: whether the road is double-decked.
  • (Edge) artificial_path: whether the edge is an artificial path.
  • (Edge) divided (networks until tiger_2016): whether the road is divided (a field left out of the later releases).
