Files outside of directories

Simulation area

• Filename: simulation_area.parquet
• Geospatial: Yes
• Columns:
  • geometry: Polygon of the simulation area
• Comment: The file contains only a single feature, representing the simulation area.

Directory osm-road-import

Raw edges

• Filename: edges_raw.parquet
• Geospatial: Yes
• Columns:
  • geometry: LineString of the edge
  • edge_id (UInt64): Identifier of the edge
  • osm_id (UInt64): Identifier of the corresponding OpenStreetMap way
  • source (UInt64): Identifier of the OpenStreetMap node of the edge’s first node
  • target (UInt64): Identifier of the OpenStreetMap node of the edge’s last node
  • road_type (String): Value of the highway tag
  • name (String): Value of the name tag (or addr:street, or ref as fallbacks)
  • toll (Boolean): Whether the way has tag toll=yes
  • roundabout (Boolean): Whether the way has tag junction=roundabout
  • oneway (Boolean): Whether the way has tag oneway=yes
  • speedlimit (Float64): Speed limit on the edge, in km/h (if available)
  • lanes (Float64): Number of lanes on the edge (if available)
  • give_way (Boolean): Whether the edge ends with a give-way sign
  • stop (Boolean): Whether the edge ends with a stop sign
  • traffic_signals (Boolean): Whether the edge ends with traffic signals
  • length (Float64): Length of the edge’s geometry, in the same unit as the CRS
  • urban (Boolean): Whether the edge is within urban areas

Urban areas

• Filename: urban_areas.parquet
• Geospatial: Yes
• Columns:
  • geometry: LineString of the edge
  • osm_id (UInt64): Identifier of the corresponding OpenStreetMap way (even numbers) or relation (odd numbers), see https://docs.osmcode.org/pyosmium/latest/user_manual/03-Working-with-Geometries/#the-pyosmium-area-type
  • landuse (String): Value of the landuse tag
