Hello all, During our editing work on lanes in Detroit and Phoenix we found some interesting situations, usually on intersections with dual carriage way, where missing turn:lanes tagging can affect the lane connectivity. So, in this situation: 42.329625, -83.16889 [cid:image005.jpg@01D3481E.54C260C0] There is no turn:lane info on the middle way, so there will be no connectivity between Way 1 and Way 4 and also Way 3 and Way 2. Our Map Analyst team mapped lane info based on Mapbox initiative<https://blog.mapbox.com/mapping-turn-lanes-in-openstreetmap-5da9bf764f0d>, in brief we mapped only where the marking is present on the road. So, on middle way from picture above, we didn't add turn:lanes, therefor will be no connectivity to left. We thought about a solution to resolve this issue, and we think that best option is to add there turn:lanes:both_ways=left on middle way like this: [cid:image006.jpg@01D3481E.54C260C0] So, in future we will map this cases like this. We'd love any input and advice from you guys. If you have any questions or comments, please let me/us know. You can add comment and share with us your opinion here: https://github.com/TelenavMapping/mapping-projects/issues/36. Also, you can find more details on that page.
Thank you, Horea Meleg, Telenav
