Median type at interchanges

What should be the median type for the left most lane shown in the image?
Should it be taken as one-way as there is no risk for head-on collision?

I dont know what direction the survey is in (drive on left or right) but its a merge lane either at top of picture or at bottom - wherever the traffic merges.

it is drive on right. what should be the median type for carriage way-A, if there is no median crash barrier present.

This should be coded a physical median of the appropriate width.

Thank you very much.
