Detailed Description

A lane boundary defining the border of a lane.

The left and right lane boundary define the width of the lane. Additionally, free markings can be defined, e.g. at construction sites. Free markings across multiple lanes may be defined multiple times for all affected lanes.

boundary_line

The list of individual points defining the location of the lane boundary (as a list of segments).

Handling of dashed lines

For dashed lines, one BoundaryPoint has to be at the start and another at the end of each dashed line segment. The first BoundaryPoint defines the beginning of the first dashed lane marking. The last BoundaryPoint defines the end of the last dashed lane marking. For example, the area between the second and third BoundaryPoint has no lane marking, and so on.

Handling of Botts' dots

For Botts' dots lines, one BoundaryPoint position has to define each Botts' dot.
