Street networks act as an urban substrate for social and economical developments and control many aspects of our society -- from disease spread to urban sprawl and population growth. In their primary representation, where edges represent roads and nodes represent roads’ intersections, street networks are essentially planar and possess many features similar to lattices. Yet, they also display very distinctive features such as heavy-tail distribution of betweenness centrality and cell areas. But as cities and their transportation systems become increasingly complex and multimodal, it is important to understand the implications of such advances to the topology and geometry of street networks. In this talk, I will examine the topological and geometrical properties of multilayer transportation systems involving more than one modality. In particular, I will discuss how the introduction of fast subway systems affect the embedding space of the multilayer transportation network.
