Lane Attributes - Definitions
Lane-level attributes can be borne by Lanes, Lane Boundaries, and Lane Groups via the reference types described in Topology Reference Types of Lane Attributes. Lane-level attributes generally override road-level attributes on the same roads.
The Protocol Buffer implementation of lane attributes is documented in Lane Attributes Format.
The following table indicates the attribution reference types for each lane attribute in the Lane Model:
