Re-routing game: The inadequacy of mean-field approach in modeling the herd behavior in path switching
Ho Fai Po, Chi Ho Yeung
Coordination of vehicle routes is a feasible way to ease traffic congestions amid a fixed road infrastructure. Nevertheless, even the optimal route configurations are provided to i…
A high-frequency mobility big-data reveals how COVID-19 spread across professions, locations and age groups
Chen Zhao, Jialu Zhang, Xiaoyue Hou +2
As infected and vaccinated population increases, some countries decided not to impose non-pharmaceutical intervention measures anymore and to coexist with COVID-19. However, we do…
Scalable Node-Disjoint and Edge-Disjoint Multi-wavelength Routing
Yi-Zhi Xu, Ho Fai Po, Chi Ho Yeung +1
Probabilistic message-passing algorithms are developed for routing transmissions in multi-wavelength optical communication networks, under node and edge-disjoint routing constraint…
Optimally coordinated traffic diversion by statistical physics
Tak Shing Tai, Chi Ho Yeung
Road accidents or maintenance often lead to the blockage of roads, causing severe traffic congestion. Diverted routes after road blockage are often decided individually and have no…
The Futility of Being Selfish -- The Impact of Selfish Routing on Uncoordinated and Optimized Transportation Networks
Ho Fai Po, Chi Ho Yeung, David Saad
Optimizing traffic flow is essential for easing congestion. However, even when globally-optimal, coordinated and individualized routes are provided, users may choose alternative ro…
Characteristics of human mobility patterns revealed by high-frequency cell-phone position data
Chen Zhao, An Zeng, Chi Ho Yeung
Human mobility is an important characteristic of human behavior, but since tracking personalized position to high temporal and spatial resolution is difficult, most studies on huma…
