The traffic and production restriction is widely used for controlling heavy air pollution. However, the effectiveness of these two policies has not been scientifically verified through a city-level study. COVID-19 pandemic caused lockdowns in many cities, which makes it possible to verify the ...
along with higher traffic congestion leading to air pollution. Specifically, in case of reduction in NOx, the association with lockdowns in large cities seems to be an obvious fall out given that significant emissions of NOxcome from fuel combustion, linked to road transportation in urban areas ...

Third, vehicle regulation should be implemented to control traffic pollution, such as strict vehicle emissions standards, bans on heavily polluting vehicles and vehicle restriction. Furthermore, the local government should also support non-motorized vehicle lanes and advocate clean energy vehicles to ...
Firstly, the enhanced control measures such as traffic restriction and emission reduction adopted in Beijing and its surrounding areas during the Military Parade were summarized and sorted out. Secondly, the air quality before, during, and after the implementation of the enhanced control measures was ...
