Can anybody please provide photos for the different objects? The variety seems to be different in different countries. --Lulu-Ann 11:19, 12 August 2008 (UTC)

and could somebody english speaking provide descriptions as well ? didn't understand how any of them differs from the others... --Richlv 17:07, 6 September 2008 (UTC)

I added Wikipedia-links to photos for Lulu-Ann and translations for Richlv --Phobie 18:05, 6 September 2008 (UTC)

Okay, let's make this page less dependent on the UK traffic rules :-) What's something like this called in English: [1] (covers the entire road crossing) and then what do you call this: [2]? It looks like you'd both call them speed tables if I look at the Wikipedia page, while they're certainly different things in our country. --Eimai 18:52, 6 September 2008 (UTC)

On nodes or ways ?

Could someone explain when it has to be on nodes and when it is part of a way ? And what happens if ways are splitted or merged ? -- Pieren 15:01, 30 November 2008 (UTC)

In most cases it would be enough to tag a node, but for table and choker it might be useful to tag a way-segment (Some chokers are longer than 50 meters and could be rendered differently). If a way will be split, tags get copied to both segments (just like every time you split a way). If you merge a way you have to deal with conflicts. Generally a way tagged with traffic_calming should not be joined with a way without that key. If you want to describe shared features of different segments use a relation! --Phobie 17:05, 30 November 2008 (UTC)

So mostly on nodes then. Should the node also be highway=traffic_calming (in addition to this key which indicates the exact type) ? Need to say this on the page -- Harry Wood 20:15, 8 February 2009 (UTC)

Traffic circle

The traffic circle is a traffic calming device in very common use in urban Australia, often described in council minutes as a mini-roundabout. This page from Seattle describes the traffic circle. --Drlizau 14th December 2008

• In Germany there is something similiar: A roundabout which is no real roundabout as it's not designated as one. They are really small and flat, so trucks and busses can cross them straigh forward. Legally you must not drive a circle, but most people do so. --Bot47 18:08, 23 October 2009 (UTC)

meetingpoint

I couldn't find a better place to put traffic_calming=meetingpoint, so I put it here. I use it for narrow 1-lane roads that have two-way traffic. Here in Norway the meeting points are signed with an M

highway=passing_place Alv 21:14, 26 July 2011 (BST)

I removed it from the page as existing tags provide the means to tag passing places and there's no need to introduce another tag. highway=passing_place and passing_places=* is already in use quite a lot according to taginfo. Jetthe 19:09, 13 August 2011 (BST)

Center island

We need a tag for center islands. This occurs a lot in my part of the United States (Oregon). I see that traffic_calming=island is used according to TagInfo. --PJ Houser 02:27, 3 August 2011 (BST)

Raised islands located along the centerline of a street that narrow the travel lanes at that location, sometimes called midblock medians, median slow points, or median chokers (from ITE [3]).

I have been using traffic_calming=island in conjunction with highway=turning_circle to map rotaries (roundabouts) at the end of a street. I would like to propose this value. It would also work for streets with islands in the middle of a small part of the street. --Panther37 17:29, 30 September 2011 (BST)

Directionality

I agree that we should tag speed bumps/humps at their location in the road (in keeping with tagging them as nodes rather than ways), but then we need to have a way to indicate when they affect only one direction of car traffic. For example, at this location [4] there is a north-south crosswalk across an east-west road. There is a speed bump to the east of the crosswalk for the westbound car traffic approaching the crosswalk, that does not extend into the eastbound lanes. And there is a speed bump to the west of the crosswalk for the eastbound car traffic approaching the crosswalk, that does not extend into the westbound lanes. We have several such installations on our campus, and others off-campus. For now, I have been tagging them with a note=* tag that indicates the direction they affect, but I'm wondering whether we should tag these instead with something like direction=forward or direction=backward, based on the direction of the way into which they have been inserted. In the absence of such a tag, the bump would be assumed to affect both directions (which is the more common situation in this area). --EdH 18:36, 21 October 2011 (BST)
