And then we end up with disputes over what areas you are and are not permitted to enter. Broken Lines, and you are permitted to enter if safe, solid lines, only permitted to enter in an emergency. Both of which technically allow you to do a u turn, in the event that a incident dictates so. And lets not even discuss yellow box junctions...

It passes the test of being physical - visible paint has been applied to the road and it passes the test of being a barrier by law.

The A15 here isn't a dual carriageway, and the "roads" between the "southbound A15" and Pottergate consequentially don't exist. There may well be turn restrictions into and out of Pottergate and into Lindum Street, but I didn't notice any when I was there recently. Needs a ground survey." This is the area concerned (to see the full extent of what's going on, open in an editor): http://www.openstreetmap.org/?lat=53.233132&lon=-0.532384&zoom=18&layers=M A reviewed of the note has replied "are you sure? the split road doesn't necessarily mean its a duel carrigeway, just that the two lanes are split, in this case by large road lines". My view was that multiple lanes in a road where there's no physical barrier are best expressed by the "lanes" tag (previously in this example, before I extended Lindum Street to the northbound lane, it was implied that you couldn't cross the road from the northbound lane to walk south into Lindum Street - something I did a couple of weeks ago without problems). A number of other roads locally have this issue - http://www.openstreetmap.org/browse/note/1573 is a more extreme one. My question is this - obviously I'm out of step with the previous mappers and the editor of the note, but who's "correct" (or are we all wrong, and should we be doing something completely differently)? I'm concerned that modelling road junctions purely for motor vehicle traffic will (as in the Lindum Street example before I changed it) be incorrect for all other sorts of traffic.
