Talk:Tag:barrier=bollard

implications

Since its introduction, this tag has been redefined ([1], [2]) to imply foot=yes and bicycle=yes. Is this commonly accepted? If yes, it should not only be in the text, but also in the template. --Tordanik 18:49, 16 May 2009 (UTC)

It was merely not explicited at the origin, but it would be clearly implied by the commonsensical definition of bollard. Circeus 00:19, 17 May 2009 (UTC)

Ambiguity

The article reads:

By default access=no foot=yes bicycle=yes is implied. So tag who can pass the node.

The first sentence suggests that if "access=no foot=yes bicycle=yes" is applicable, I shouldn't have to add extra access, foot or bicycle tags. However, the second sentence tells me to add those tags. What's a simple soul like me to do? --Sybren 16:18, 6 July 2009 (UTC)

Automatic, "Rising" Bollards

Some bollards retract into the ground automatically, either in response to a key system or on a timer^[1]. A couple of schemes have emerged for representing this, though neither is was in particularly widespread use at the time of writing:

• Tag as above, and add bollard=rising. 44 uses as of 2011-04-26^[2].
• Tag as above, and add automatic=yes. 29 probable uses as of 2011-04-26^[3].

The bollard=* scheme is more extensible, and is probably the better tag. TODO: suggest some other values, or use a Taginfo box to refer readers to a dynamic list.

What about bollard=fixed for example the stumps of concrete, and bollard=removable for those that can be manually removed/lowered (usually a key is needed) for authorised access. --User:LastGrape

Sounds good to me. Let's discuss possible values over at Key:bollard. There was just enough usage in the db to justify a descriptive wiki page (with a taginfo box), and automatic=yes doesn't really seem to have caught on. --achadwick 20:10, 2 March 2012 (UTC)
