Which public places are riskiest during the pandemic?
That’s the question researchers at Stanford University set out to answer with a new computer model.[1]
They analyzed cellphone data from 98 million Americans living in 10 major cities: Atlanta, Chicago, Dallas, Houston, Los Angeles, Miami, New York City, Philadelphia, San Francisco, and Washington, D.C.
The data showed where people went in the course of a day, how much time they spent there, and how crowded the places were.
