Hi I hope I can make this clear, I am using OSM data to build a network for traffic simulation (using sumo). [SUMO](http://sumo.dlr.de/wiki/Main_Page)). I often notice errors in the data when it comes to the available number of lane, I have fixed one as an example: https://www.openstreetmap.org/api/0.6/changeset/32608483/download example [Changeset 32608483](http://www.openstreetmap.org/changeset/32608483). In the linked case, I am guessing it is okay to make the change but I have some other cases where a single way has its number of lanes change (some part of the way has 2 lanes, some part has 3, some other has 4 when the lane reaches an intersection). In this case, for the simulation purpose, I need to split this into three different ways, with the correct number of lane for each of them. My question is: is Is it okay to make this kind of split and commit them to the OSM database? in In some cases, it can significantly increase the number of ways without improving the quality of the map render.
