Median Type for Roundabout

What should be the median type for this Roundabout? It occupies more than 100m.

Thank you so much.

Looks like median type is central hatching (>1m)

But what about inside the roundabout? What should be the median?

If the start and end point of your 100m segment is on the roundabout then you can record the concrete barrier seen in the image. If not, then its the central hatching on approach.
