The capital has announced a one-year extension for traffic restrictions aimed at reducing congestion and improving air quality in Beijing, the South China Morning Post reported. The measures will take a fifth of the city’s 3.61 million vehicles off the roads each weekday, according to the Beijing Traffic Management Bureau. Cars will be restricted based on whether they have a license plate that ends in an odd or even number. The restrictions were first announced in October following public debate over whether to extend traffic restrictions that helped keep skies clear during the Beijing Olympics and Paralympics. They were set to expire April 10. The scheme during the games gave Beijing’s 17 million residents a chance to experience clear summer skies as the city recorded its lowest August pollution levels in 10 years.
