许多复杂的网络只是较大系统的一部分，其中许多共存的拓扑相互作用并相互依赖。我们引入了一个分层模型，以方便对这类系统的描述和分析。作为应用实例，我们研究了三种交通系统中的负荷分布，其中下层是物理基础设施，上层是交通流。这种分层视图使我们能够捕捉到实际负载和常用负载估计器之间的根本区别，这解释了为什么这些估计器不能接近实际负载。
Many complex networks are only a part of larger systems, where a number of coexisting topologies interact and depend on each other. We introduce a layered model to facilitate the description and analysis of such systems. As an example of its application, we study the load distribution in three transportation systems, where the lower layer is the physical infrastructure and the upper layer represents the traffic flows. This layered view allows us to capture the fundamental differences between the real load and commonly used load estimators, which explains why these estimators fail to approximate the real load.
