Segment

Segments are paths which can be traveled by people or objects.

Typesegment

Segment geometry represents the center-line of a path that a person or object may travel. Segment properties describe both the physical attributes (e.g. road surface and width) and non-physical attributes (e.g. access restriction rules) of that path.

Two segments are physically connected if a common connector is referenced from the connector property of both segments. Where this occurs, both segment geometries must contain the common connector's coordinates. A physical connection between segments indicates that it may be possible to travel from one segment to the next at the connected location provided the segment properties do not indicate a restriction, such as a turn restriction, which would prevent the transition. Conversely, two segments are not physically connected -— even if their geometries intersect —- if they do not share a common connector.

Subtypes

A segment may have one of three possible subtypes.

subtyperoad

A road segment represents a section of any kind of road, street or path, including a dedicated path for walking or cycling, but excluding a railway.
