Hi everyone! I have recently been mapping a lot of turn:lanes information on highways in my area, but ran into the issue that turn:lanes fails to store all of the necessary information in many junctions. Multi-lane roundabouts, single point urban interchanges, 5 way intersections with divided roads, and other cases are all too complex for turn:lanes to handle.
Because of this, I have created a proposal for a simple type of from-via-to relation that would provide information about how lanes in the "from" way connect to those in the "to" way at any point where it isn't clear. These relations are very similar to turn restrictions, and like turn restrictions, wont be needed in most intersections. The relation would also be able to store the same information as could have been possible with transit:lanes, just without the many maintenance issues that came that system. https://wiki.osm.org/wiki/Proposed_features/Connectivity All feedback on how to potentially improve the proposal would be highly appreciated! Thanks, Leif Rasmussen
