A *very* quick look at that against Bing imagery in JOSM reveals a
pretty broad selection of things around the world that get classified as
* Yer classic blob of paint in the middle of the road. This might the
predominant UK usage, and it's common here, but I'm guesstimating it's
more like 50/50 even in the UK because (and this came as a proper
surprise to me) it's also used for:
* Small roundabouts/traffic circles with defined centres. Sometimes
with quite large planted trees.
* Big roundabouts/traffic circles, but fairly rarely; perhaps
predominating in non-English-speaking countries, or countries which have
no concept of size distinctions between their traffic circles?
* Unmarked passing places, where cars can overtake each other on
* Turning circles at the ends of residential roads, with or without
* AFAICT, just random intersections without anything specific.
I wonder how it would be possible to get a more systematic analysis of
this data extract. Perhaps a small app which grabs relevant Bing tiles
for nodes at random and asks the user to classify as yes/no/can't tell...?
(But in short the db data sucks and so does the wiki documentation.
Perhaps the question we should be asking ourselves is which one to fix
up and how... sigh.)
