<div dir="ltr">I see two good options: <div>1) Split the two lanes into two ways where they first split apart (but aren't yet physically divided). This doesn't follow the "physical divider" rule, but since the road markings are acting as a physical divider, and they are much more than just a line, an exception to that rule seems fine.</div><div>2) Just pretend that the road markings are like any other line and tag change:lanes instead of two separate ways. Then, you could use a new tag like "width:dividers:backward=3" to mark that the lane divider is 3 meters wide. </div><div><br></div><div>I would probably just go with the first one for now, since it's a bit difficult to physically cross that lane divider with a vehicle and the lane splits off anyway.</div><div><br></div><div>... </div><div><br></div><div>I've been considering starting a proposal for mapping the widths of lane dividers recently, since there are many cases where they aren't just lines. Perhaps some tag like "width:dividers=0|0|4" or similar could work, where each number represents a divider between two lanes (that example would be for a one way road with 4 lanes, the right of which is separated by a 4 meter lane divider).</div><div>What do people think of a new tag like this? I personally think something other than "|" should be used for dividers, so am looking for a better syntax. If people like the idea, I would be happy to start a new proposal.</div><div><br></div><div>Leif Rasmussen</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Sep 6, 2019 at 3:15 PM Markus <<a href="mailto:selfishseahorse@gmail.com">selfishseahorse@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hello everyone<div dir="auto"><br></div><div dir="auto">I'm unsure how to map the following situation:</div><div dir="auto"><br></div><div dir="auto">There are two lanes approaching a roundabout, both with different destinations.
