The spread of traffic jams in urban networks has long been viewed as a complex spatio-
temporal phenomenon that often requires computationally intensive microscopic models for …

The spread of infectious diseases at the global scale is mediated by long-range human
travel. Our ability to predict the impact of an outbreak on human health requires …

Urban transportation systems satisfy the essential mobility needs of the large-scale urban
population, but it also creates an ideal environment that favors the spread of infectious …

The study of complex networks sheds light on the relation between the structure and function
of complex systems. One remarkable result is the absence of an epidemic threshold in …

We study the dynamical process of congestion formation for large-scale urban networks by
exploring a unique dataset of taxi movements in a megacity. We develop a dynamic model …

A critical phenomenon is an intrinsic feature of traffic dynamics, during which transition
between isolated local flows and global flows occurs. However, very little attention has been …

Global transport and communication networks enable information, ideas, and infectious
diseases to now spread at speeds far beyond what has historically been possible. To …

The emergence of novel infectious diseases has become a serious global problem.
Convenient transportation networks lead to rapid mobilization in the context of globalization …

Improved mobility not only contributes to more intensive human activities but also facilitates
the spread of communicable disease, thus constituting a major threat to billions of urban …

The increasing agglomeration of people in dense urban areas coupled with the existence of
efficient modes of transportation connecting such centers, make cities particularly vulnerable …
