Topology Reference Types of Lane Attributes

Attributes reference lanes in the following ways:

• Lane Parametric Range: Applies to the parametric range of a Lane, as designated by starting and ending length fractions (i.e., values from 0 to 1) on the associated Lane.
• Lane Parametric Point: Applies to a single point along a Lane, as designated by as a fractional distance (i.e., values from 0 to 1) from the Lane's start.
• Lane Boundary Parametric Range: Applies to the parametric range of a Lane Boundary, as designated by the starting and ending length fractions (i.e., values from 0 to 1) on the associated Lane Boundary.
• Lane Group Parametric Range: Applies to the parametric range of a Lane Group, as designated by the starting and ending length fractions (i.e., values from 0 to 1) of the associated Lane Group.
