Hi OSM contrubutors, here you can see the result in the software (because on the classic map it isn’t visible with classic layer)
We need to use the key lanes = x (x is the number of way in the both direction) in this case: lanes=4. We indicate the number of lane in the both directions: lanes:backward=2 lanes:forward=2 We need to use the lane on the left road if we want to turn left placement:forward=left_of:1 This is the mark sign indicator on the road turn:lanes:forward=left;through|through;right
Enjoy yourself

Of course all can improve it again (my work, my contribution)
P.S.: Don’t forget, it’s for to do a “map” and if we want somebody use it, it’s must be a little bit “pleasant”…). But in the reality, it isn’t a simple map…

Since there are 4 lanes, and you positioned the OSM-way in the middle of the 4 lanes, there is no need to add placement:forward=left_of:1. A placement is only needed when the OSM-way is not in the middle of the real road.
Happy lane-mapping from another turn:lane mapper

Hi escada, I’m glad to have a follower with an interesting answer. This is what I think: “in this country “France” we driving on the right side of the road. If we want to turn left, so, we must stay on the left side. Probably you’re right, however I prefer to keep this tag on the road. The key: “placement” is a proposed key, so isn’t really important at this time in OSM project. But the key lanes and turn are “important” for a good understanding, rendering on the map (for to have a nice map). OSM project is very interesting and we must take care of it for the respect of his “designers”… Thanks for your answer, your help. Have a nice week.

I recently discovered a neat tool that help fixing highways by displaying lanes, turn lanes and destinations, I thought it would be relevant to mention it here :

Hi gileri, thanks for this information who can help the persons who start mapping and not only, the community of OSM, all contributors of this project.

Ok, finally I will deleted the “placement” key as soon as possible. Best regard to all.
