A causal evaluation of Bogota's cable car illustrates the transformative potential of mobile phone data for policy analysis
Elena Lutz, Sam Heroy, David Kaufmann +1
Transport infrastructure is vital to the functioning of cities. However, assessing the impact of transport policies on urban mobility and behaviour is often costly and time-consumi…
Are neighbourhood amenities associated with more walking and less driving? Yes, but only for the wealthy
Samuel Heroy, Isabella Loaiza, Alex Pentland +1
Cities are home to a vast array of amenities, from local barbers to science museums and shopping malls. But these are inequality distributed across urban space. Using Google Places…
Rigidity percolation in random 3D rod systems
Samuel Heroy, Dane Taylor, Feng Shi +2
In composite materials composed of soft polymer matrix and stiff, high-aspect-ratio particles, the composite undergoes a transition in mechanical strength when the inclusion phase…
COVID-19 policy analysis: labour structure dictates lockdown mobility behaviour
Samuel Heroy, Isabella Loaiza, Alexander Pentland +1
Countries and cities around the world have resorted to unprecedented mobility restrictions to combat Covid-19 transmission. Here we exploit a natural experiment whereby Colombian c…
Metropolitan-scale COVID-19 outbreaks: how similar are they?
Samuel Heroy
In this study, we use US county-level COVID-19 case data from January 21-March 25, 2020 to study the exponential behavior of case growth at the metropolitan scale. In particular, w…
Unravelling the forces underlying urban industrial agglomeration
Neave O'Clery, Samuel Heroy, Francois Hulot +1
As early as the 1920's Marshall suggested that firms co-locate in cities to reduce the costs of moving goods, people, and ideas. These 'forces of agglomeration' have given rise, fo…
Rigid Graph Compression: Motif-based rigidity analysis for disordered fiber networks
Samuel Heroy, Dane Taylor, Feng Shi +2
Using particle-scale models to accurately describe property enhancements and phase transitions in macroscopic behavior is a major engineering challenge in composite materials scien…
