</div>Yes, it's certainly quite expressive, at the cost of complexity - and<br>
having to use relations.</blockquote><div><br><br>+1<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> One of the advantages of simply setting a<br>
"divider=" tag is its simplicity and succinctness. One tag, and you've<br>
got something that will render nicely, and be useful for routing.<br>

I see four essential tag values:<br>
<br>
divider=none (can freely cross)<br>
divider=marked or something (do not route a car across this, but a<br>
pedestrian could cross it)<br>
divider=median_strip (again, do not route a car across this, but you<br>
could drive across it in an emergency)<br>
divider=barrier (a physical barrier that would probably stop a pedestrian)<br>
<br></blockquote><div><br>yes, I see these as possible dividers/barriers for my proposed area-relation. The area-relation allows optionally to add a divider/barrier-role, which can be either area (e.g. if it is a very thick irregular wall), way or node (nodes can be barriers, but also the opposite: entrances (interruptions, openings), gates, lift_gates, lowered_kerbs, ...)<br>
</div></div>And it can solve the lane-problem (map lanes explicitly and do not confound them with other highway-ways), connect bicycle-tracks to the adjacent road and define the height of the kerb (without having to map the kerb, but beeing able to map the kerb-lowerings), ....<br>
