Air pollution levels compared as Prague’s Národní is closed to traffic
Prague’s Národní St. was closed to cars on Thursday. Experts used the closure of one of the city’s main thoroughfares to measure the difference in air pollution compared to on normal days. The event was part of the European Week of Mobility and coincides with International Car Free Day. The Prague councilor responsible for traffic, Petr Dolínek, said the city often had air pollution as high as Ostrava; however, while the cause there is industry, in the capital it is traffic congestion, he said.
