Mesoscopic simulation does not distinguish between lanes (except for some turn lanes at junctions). The mesoscopic models is based on queues. Often, a queue models the whole edge and the number of lanes only modifies the capacity of that queue. Placing one e1Detector per edge is therefore enough to obtain the whole data.
