Road
A path along which vehicles travel. It is typically, although not necessarily, paved and intended for cars.
Relationships      
Parents 地域 A topographic location. Regions encompass surfaces of Objects, imaginary places, and GeographicAreas. Note that a Region is the only kind of Object which can be located at itself. Note too that Region is not a subclass of SelfConnectedObject, because some Regions, e.g. archipelagos, have parts which are not connected with one another.
  Roadway Roadway is the subclass of LandTransitways that are areas intended for surface travel by self-powered, wheeled vehicles, excluding those that travel on tracks. Roadways have been at least minimally improved to enable the passage of vehicles. Roadways include dirt and gravelled roads, paved streets, and expressways.
