[OSM-talk-be] Mapping of Cycling Networks

[Ben Laenen]

There's a bit of talk on the discussion page, and elsewhere on the wiki, but 
an example is the best way to understand it:

http://www.openstreetmap.org/?lat=51.07755&lon=4.16521&zoom=16&layers=00B0FTF

junction 69 there is also such a "double junction".

As you see the way between the two 69's is in this case part of all four route 
relations. The idea is that you get at the first junction, you want a route to 
the next junction, so say you arrive at the south 69, you have three departing 
routes: west to 55, nothing special there, and two northwards on the part 
between the two 69's: to 09 and 78, both those routes are one way only so they 
get forward/backward roles (oneway, because when you go the other way, you 
arrive at the north junction first at which point you get the next route 
there). And vice versa if you get at the north junction first.

There are many more examples to be found elsewhere to understand it better, 
the 78 junction north of 69 for example is a fun one, junctions on roundabouts 
also become pretty fun work.
