> Ids of internal lanes within clusters do not match at all, e.g.,

> def getLane(self, laneID):
> split = laneID.rsplit("_")
> edge_id = "_".join(split[:-1])
> lane_index = int(split[-1])
>
> edge = self.getEdge(edge_id)
> return edge.getLane(lane_index)

> This should work with all sorts of lane ids as it only focuses on the
> last underscore in the id which should always be generated by
> sumo/netconvert itself.
