Near Road Air Quality - A PIARC Briefing Note

“Air pollution problems are often observed in the roadside areas of metropolitan regions, where a lot of emission sources such as factories, business offices, residential houses and vehicles accumulate.
Such air pollutions are caused by emissions of SO2, NO2, CO, HC, PM10, PM2.5 etc. which are designated as air pollutants in most countries across the world.
In order to carry out air pollution abatement measures, we have long-term evaluation values and short-term evaluation values as regulation standards of air pollutant emissions, and as a step of implementation of the measures we compare real-time evaluation values with the short-term values of regulation standards.”
The purpose of this briefing note is to summarize recent research related to air pollution in the near-road environment to support further investigation of:
•   traffic operations to minimize the health impact of vehicle emissions;
•   implement operational mitigation measures.
