segment

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

Typesegment

Segment geometry represents the center-line of a path which may be traveled. 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 connectors 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 in a particular case. Conversely, two segments are not physically connected—even if their geometries intersect—if they do not share a Connector in common.

Sub-Types​

A segment may have one of three possible sub-types.

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).
