What's in a crowd? Analysis of face-to-face behavioral networks [PDF]

open access: yesJournal of Theoretical Biology, 2011
The availability of new data sources on human mobility is opening new avenues for investigating the interplay of social networks, human mobility and dynamical processes such as epidemic spreading. Here we analyze data on the time-resolved face-to-face proximity of individuals in large-scale real-world scenarios.

Behavior Analysis-Based IoT Services For Crowd Management

open access: yesThe Computer Journal, 2022
Abstract With the world population growing exponentially reaching 7.8 billion people in 2020, the issue of crowd management has become more difficult especially when the situation requires social distancing (e.g. due to COVID-19). The Internet of Things (IoT) technology can help in tackling such issues.
