Street-Level Air Quality in the 18 Districts, Hong Kong

In order to evaluate the risk of exposure of the road users, including pedestrians, drivers and commuters, to air pollutants on the streets, the Mobile Real-time Air Monitoring Platform (MAP) was deployed to study the street-level air pollution of the 18 districts in Hong Kong. The results were used to characterize the spatial distribution of street-level air pollution and identify a number of air pollution “hotspots” in these districts as well as to illustrate how the traffic conditions and open space affect street-level air pollution.
