Urban Road Networks in Spatial Representation: Spatial Geometric Dataset

This dataset comprises simplified URN data in spatial representation from 35 selected cities. The data record encompasses the road network and the geometric details of crossings, stored in the “Spatial Geometric Dataset” in GeoJSON format. These datasets are readily applicable for spatial analysis in GIS software such as QGIS or ArcGIS.Spatial Geometric Dataset. Include link and node geometry data of 35 cities.1. RoadSegments (GeoJSON format):Link_id: A self-generated unique identifier for each road segment, utilized in the construction of customized graphs.Length: The length of the road segments.Intersected_node_set: Represents the node_id of the crossings intersected by this road segment, used in the construction of a bipartite graph.Interested_link_set: Represents the node_id of the crossings intersected by this road segment, used in the construction of a dual graph.2. Junctions (GeoJSON format):Node_id: A self-generated unique identifier for each intersection.Interested_link_set: Represents the link_id of road segments intersecting at this crossing.
