Solid pillar or pillars made of concrete, metal, plastic, etc., and used to control traffic. Bollards may be used to block vehicular traffic completely while allowing passage of pedestrians and bicycles, or to prevent criminals using vehicles from ramming shops.
How to Map
Simply add the tag barrier=bollard to a new node positioned where the bollard is.
By default access=no, foot=yes, bicycle=yes and similar are implied. If something usually not blocked by bollards (cyclist, horse etc) would be blocked then tag this 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).
In some cases people map every bollard in a row of bollards as a separate node. In such case ensure that bollards are also placed at centerline of roads/footways crossing this row of bollards.

Bollard type
The bollard's type can be expressed in more detail by adding a bollard=* tag with an appropriate value.
Examples:
- bollard=fixed (cannot be (re)moved, rotated or lowered, not even with a key or tool)
- bollard=removable (can be removed, sometimes a special tool is required)
- bollard=rising (can be lowered to allow passage or lifted to prevent it)
- bollard=foldable (can be folded/rotated such that the bollard lies on the ground)
- bollard=flexible (made of soft material so that it can bend)
Do not use the values irremovable or unremovable, use bollard=fixed instead.
