Abstract Click to copy section linkSection link copied! Mobile monitoring of air pollution has been extensively employed in environmental and epidemiological studies. However, previous monitoring campaigns, which typically involved only one or two vehicles operating during temporally incomplete and imbalanced daytime, were limited in spatiotemporal coverage, resolution, and representativeness.

The commuting microenvironment accounts for a large part of students’ diurnal exposure to air pollution, especially in cities in developed countries where air pollution is caused predominantly by vehicle traffic. Accurate quantification of students’ exposure and pollution dose during their commute from home to school requires their home addresses and details of the schools they attend. Such details are usually inaccessible or difficult to obtain at population scales due to privacy issues.
