But how did they affect people’s everyday movements, especially in urban areas? A new study by researchers from Binghamton University and Brazil’s Fluminense Federal University analyzed cellular data to see how the coronavirus threat affected travel in Rio de Janeiro. The anonymized data from Brazil’s second-largest urban area, collected between March and July, included 2 million users per day and 120 million connections to antennas around the Rio metro area. By pinpointing the locations of those connections, researchers could create a day-by-day look at how many still trekked around the city and where they went, as well as how many residents stayed home as advised.
