Visitation entropy, the Shannon entropy of an individual's distribution of visits across locations, is a widely used metric in the human mobility literature. Yet, its widespread us…
Empirical Trajectory Sparsity Biases Mobility-Informed Epidemic Modeling
Federico Delussu, Francisco Barreras, Yuan Liao +2
GPS mobility data are increasingly used in epidemic modeling, allowing the construction of co-location networks or population flows. These trajectories typically exhibit high tempo…
Women's mobility networks enable more efficient travel
Sílvia de Sojo, Sune Lehmann, Laura Alessandretti
Our understanding of gender differences in mobility is marked by a clear tension: surveys portray women's movements as more complex than men's, while digital traces suggest less di…
Urban mobility enables deprivation bubble breaking in Indian and Mexican cities
