These cities have the world’s worst traffic congestion—but that could change fast

In the world’s biggest cities, the demand to drive far outstrips the supply of roads. Traffic analytics company Inrix puts out annual data on which cities in the world have the most congestion. In 2019, the two cities that topped the list were Bogota, Colombia and Rio de Janeiro, Brazil, with the average person losing 191 hours and 190 hours to traffic each year, respectively.
