As nations across the world try to limit the spread of COVID-19, the disease caused by the novel coronavirus, many cities, regions, and even entire countries have been placed under severe restrictions, keeping people who would normally be on the roads in their homes.
To show how this has affected cities throughout the world, BuzzFeed News has teamed up with Mapbox, a mapping and location data company, which provided information on traffic volumes before and after the COVID-19 crisis escalated. In each case, the “After” view shows traffic patterns Monday March 30, local time. The “Before” view shows Monday January 13, before the coronavirus had spread across the globe.
Brighter greens and yellows indicate the presence of more vehicles on the roads. As the streets and highways empty, cities go dark.

The Bay Area counties of Alameda, Contra Costa, Marin, San Francisco, San Mateo, and Santa Clara issued a shelter-in-place order, which went into effect 12:01 a.m. on March 17. Residents were told to leave their homes for “only the most essential needs.” On March 18, California Gov. Gavin Newsom ordered people across the entire state to stay home unless absolutely necessary.

Just an hour before Newsom’s announcement, city officials in Los Angeles issued a similar order. Even before then, fewer Angelenos were taking to the city’s freeways than normal.

New York currently has more confirmed cases than any other US state. Public schools in New York City are closed, as well as restaurants, bars, gyms, movie theaters, and cultural institutions including the Metropolitan Museum of Art and the New York Public Library. On Mar. 20, governor Andew Cuomo ordered all non-essential workers across the entire state to stay home.

The British government initially advised people who might be infected to self-quarantine but avoided wider restrictions on activities and travel. But it changed tack on March 16 after an expert report suggested this would lead to the health system being overwhelmed. Now people are being advised to avoid “non-essential contact,” and schools are being closed from March 20 until further notice.

The coronavirus now spreading across the globe was first identified late last year in the Chinese city of Wuhan. By late January, it and other badly affected cities were quarantined. Economic activity across the entire nation slowed, visible to orbiting satellites through a drop in air pollution.

After China, South Korea was the second country to see an explosive rise in cases. Unlike other nations, it has managed to bring its epidemic under control, launching a massive testing campaign and aggressively tracking the contacts of people who tested positive.
Because this early intervention allowed it to get the spread of the virus under control, South Korea has not had to shut down entire cities. “South Korea is a democratic republic, we feel a lockdown is not a reasonable choice,” Kim Woo-Joo, an infectious disease specialist at Korea University, told Science. Still, normal levels of traffic have not yet returned to the streets of its capital city.
