There's also http://taginfo.openstreetmap.org/tags/type=advanced_stop_line
which uses a relation containing the way approaching the ASL and the node of
the junction of the ASL. With this method it's easier to determine the
direction of approach to the ASL than just tagging a single node alone.

Can I gauge everyone's opinion on the following? We currently have four ways
of representing a



  (and maybe others?)

These should probably be merged into one tag because they all refer to the
same thing.

There aren't very many of them in OSM right now, but from personal
experience they're exceedingly common things in UK towns and cities.

We can pick and choose the tag a little right now, given that it's not very
well established. Let's not go with "asl"; abbreviations are generally  bad
practice. "advanced_stop_line" is bulky. "bike_box" is an Americanism,
previously unknown to me.

Personally, I like "cycleway=advanced_stop": it captures the forward
position on the thing and the fact that it's a stop line, like the well
established "highway=stop". Avoiding use of the terms "line" or "box"
avoids concentrating too much on the physical form of the thing. I suppose
it could be used with railway=* for trams, busway=* for buses and so on.

Any other suggestions?
