Title: Standard for Property Graph Description of Road Networks
Scope: This standard aims to define the property graph description of high-quality road network data, including the lanes, roads, intersections, etc., to support high efficiency of data storage and retrieval. The lanes, roads, intersections shall be represented as nodes in the property graph, while the topology of road network is represented by edges in the property graph. This standard also defines properties of graph nodes and edges, as well as data types, value ranges, and basic access interfaces of these properties.
