Hi Terry,
The lane types “Curb” and “Raised Median” have different functional intent. The “Raised median” lane primarily serves as a barrier or separator between opposing traffic lanes. “Curb” lane enhances pedestrian safety and acts as boundary between the roadway and adjacent areas like the sidewalk. Curbs also help channel water to drainage systems. Fillets hold more importance for curbs where the vehicle transition between the road and the curb is often required to be smooth. The vehicle interaction with the edge of the median or the fillet is of less functional importance for “Raised Median” type lanes. You can refer to the following documentation link that explains the difference between the two lane types in the “Attribute” pane:
A possible workaround is to use the “Curb” lane itself as a median-type lane as all the attribute options in “Raised Median” lane are also available in “Curb” lane.
I hope this helps with your query.
