Build on air quality exercise

Beijing's traffic and air quality exercise should not only be for the coming Olympic Games, says an article in Oriental Morning Post. The following is an excerpt:

The municipal government of Beijing launched a traffic and air quality exercise from Friday to yesterday. Vehicles with odd and even license plates were alternately allowed on the roads during these four days. The exercise was to study the impact of car emissions on air quality, the impact of car numbers on traffic and whether public transportation could cope with the reduction of private cars.

The first two days saw an improvement in traffic flow, a reduction in accidents and better air quality. And public transportation satisfied the needs of commuters.
