ULAN BATOR, Sept. 23 (Xinhua) -- Mongolia held its Car-Free Day here on Saturday to reduce traffic congestion, promote healthy living and cut down on vehicle emissions, according to the municipal government of Ulan Bator.
On Car-Free Day, all main roads of the capital city were closed to both private cars and public transport vehicles and only opened for pedestrians and cyclists.
For many years, air pollution and traffic jams have been the most pressing issues in Ulan Bator, home to around half of the country's 3.4 million population.
The Car-Free Day is observed twice a year in the capital city, once in spring and once in autumn. ■
