Problem number 2... Shibuya Station in Japan..
9 Railway lines/platforms
Trunk road going over rails
expressway going over rails
I just remembered, that nodes attached to ways have the following XML
<way id='-7' visible='true'>
<nd ref='-2' />
<nd ref='-6' />
What's to stop us tagging the node reference with a width?
<way id='-1' visible='true'>
<nd ref='-1' width='50' lanes:left='2' lanes:right='3' />
<nd ref='-2' width='40' lanes:left='2' lanes:right='2' />
This is tagging the way, but at the node references.
