How do I map this kind of intersection in terms of adding lane numbers, turning lanes and width? For example, what I have so far for the bottom road leading up to the intersection is: lanes = 3 lanes:forward = 1 lanes:backward = 1 turn:lanes:backward = 1 And I don't have width added yet, but I was thinking of adding it as: width = 15' Or should I specify which lane has which width? In general, for roads and streets with lane tags on the way, does width specify for the entire width of the way? And what else should I add/edit to make the bottom road leading up to the intersection complete? Thank you!

You need to split the highways at the intersection and at the position where the lanes start or stop. Let's take the road north of the intersection. Assuming the way runs north to south the tags would be:
If the way runs south to north forward and backward would have to be swapped, but the order in the turn:lanes is always left to right in driving direction (not way direction). If there are no markings on the right lane you could also tag There are some examples on the Wiki |

I think the correct tagging would be (speaking of North Milledge Avenue and assuming it goes S>N): 1

I agree with the previous answers that turn:lanes:forward= and/or turn:lanes:backward= are the tags to be use. I personally like to use 'none' instead of nothing between the "|" lane delimiters as I find it easier to read especially on wide streets with lots of lanes. (Software tools shouldn't care one way or the other.) You can tag all this by hand, but the turn lanes plug-in for JOSM makes it really, really easy and assures that you have the proper match up between the number of lanes specified in the turn:lanes:*, lanes:forward, lanes:backward tagging and the total lane count. |
