No, we do not use this tag yet. Somebody on the forum already commented that we could use these speed cameras as alternative source, but it is not implemented yet. Or are you interested in weight/height? thanks Martin
No, I'm interested in correct reporting for this. Currently I will be warned if there is a speed camera in the near. So if there is a camera in both directions I will be warned twice.
highway=speedcamera is an old method. They recommend to use it for compatibility reasons. The better way to describe such things is to use enforcement (link in first post).
If anybody is interested in speed cameras extracted from the whole planet (node with tag 'highway'='speed_camera') here is CSV file (gzip 180kB). These are only ID, X, Y (in miliseconds - digger should still accept that). There is no speed or heading direction.
@blubb - ok, thanks for info. I will have to wait for processed August 2013 planet.osm (now the "enfocement" tag was not filtered yet).
