+***Explanation***
+
+- **`segment_type`**: Defines the classification of road segments (e.g., National, Main Road, Gravel Road).
+- **`segment_status`**: Describes the current status of road segments (e.g., In Use, Planned, Under Construction).
+- **`segment_surface`**: Specifies the surface material of road segments (e.g., Asphalt, Gravel, Dirt).
+- **`segment_condition`**: Records the current condition of road segments (e.g., Good, Poor, Flooded, Under Repair).
+- **`intersection`**: Represents physical nodes (points) where road segments begin, end, or connect.
+- **`road`**: Represents logical roads, typically composed of one or more connected road segments.
+- **`road_segment`**: Represents physical sections of a road, linking two intersections and holding detailed metadata including type, status, surface, and condition.
