Openstreetmap-carto: Move loose bollards to z19

[kocio-pl]

It would be good to show bollards which are not part of the road later (z16->z19) to not clutter the map. How could I select loose/road bollards using SQL?

[HolgerJeromin]

Do you have an example where this is a problem?

You'd have to do something similar to the turning circle logic

Here's a row of loose bollards, for example: http://www.openstreetmap.org/node/3102111067#map=17/52.22842/21.00874
Here is another one, even more visible, for example: http://www.openstreetmap.org/node/3740368877#map=16/52.2551/20.9834

I'd like to revive this issue. Loose bollards are still shown much too early. This does neither reflect their size nor their importance.

what do you mean by „loose“? Is there a difference between a fixed bollard and a removable one, for a normal map user (i.e. someone not autorized to remove the bollard)?

Should we distinguish between strong bollards and those you can run over with only light damage?

When speaking about size, should we treat bollards differently according to their diameter?

maybe barrier=bollard is not the right tag for something that doesn’t block a highway?

"Loose" means here "not a node included in some road". Typically they block the access to the sidewalk.

Map user would never be sure - it's just a warning that the road might be not passable. However for this we have access tag and it's better visible.

Since when are barrier= object limited to highways? It is a barrier and it is a bollard, so yes, I think it's the right tag.
