Hello, all your questions are indeed answered by "this is the way it works in the meso model". The mesoscopic simulation generally, doesn't distinguish individual lanes and rather places all vehicles on an edge in the same queue (or a series of queues for long edges). Only for the last segment before an intersections with turning lanes, does the model switch to using one-queue per lane. see https://sumo.dlr.de/docs/Simulation/Meso.html#longitudinal_model
