• refline: refers to stop line of the detection area

Sample detection area in .osm format is shown below:

Road Marking

This regulatory element specifies related road markings to a lanelet as shown below.

* Note that the stopline in the image is for stoplines that are for reference, and normal stoplines should be expressed using TrafficSign regulatory element.
