Characterizing Human Mobility from Cellular Network Data

Abstract: An improved understanding of human mobility patterns would yield insights into important societal issues such as the environmental impact of daily commutes. In this work, we analyze anonymized cellular network data to identify important locations in people's lives, for example home and work. Starting with temporally sparse and spatially coarse location information, we use clustering and regression to identify important places for arbitrary cellphone users. We validate our results against ground truth provided by volunteers and against census statistics. Finally, we calculate home-to-work commute distances and estimate the carbon in footprints of those commutes for hundreds of thousands of anonymous users in the Los Angeles and New York metropolitan areas.

This is joint work with Richard Becker, Sibren Isaacman, Stephen Kobourov, Margaret Martonosi, James Rowland, and Alexander Varshavsky.
