How to Map
By default access=no, foot=yes, and bicycle=yes is implied. If that isn't true, tag who can pass the node explicitly. Always place a bollard node before a junction node unless it affects all traffic across the junction in all directions.
Rows of bollards can be represented as ways, including closed ways: area=no is implied. If rows of bollards are laid across highways, make sure they share nodes with what they block since routing happens at the edges of area highways at present. Larger obstacles needing a representation as a surface for closed ways (area=yes) should use other barrier=* types (such as block or debris).
The bollard's type can be expressed in more detail by adding a bollard=* tag with an appropriate value.
