Roadside severity - how to code this case?

You could code the left side as a concrete safety barrier less than 1m from the edge and on the right, as the slope is probably less than 2m, you could record the concrete blocks as low rigid objects, possibly >5m from the edge.

iRAP coding manual recommands the concrete blocks spaced at intervals can be coded as unprotected safety barrier end, referenced in page 50.

Which attribute code is correct?

Code 15
