text: Well, I have never seen 'width' tagged on a barrier and I would find it weird due to these reasons: 1. mappers do not roam around with distance meters to input the 'width' properly, but they can guess whether a block or bollard is intended to disallow cars or above. 2. it would be funny to input your width in a navigation app when you are in pedestrian or bicycle mode ;) I have yet to see one that would even offer that possibility.
