Air quality and noise - Built environment indicator

Movement infrastructure needs to be assessed for impacts at a local scale. Activities associated with high traffic volumes can affect places, just as places can impact on the movement of vehicles. Air pollution from motor vehicles, particularly fine particles (PM2.5) and nitrogen dioxide (NO2), has health impacts on exposed communities.

This indicator will support practitioners to understand air quality and road traffic noise levels and their health impacts for non-complex scenarios. Based on the outcome of the assessment, practitioners can determine suitable land-uses for the environment adjacent to road corridors.

Practitioners can use the risk of land-use conflicts metric to assess the level of risk of exposure to air pollution from road traffic for both residential and sensitive locations.

Practitioners can use the monetary environmental cost of traffic metric to assess the economic impact of air pollution, greenhouse gas emissions and noise from road traffic to society.

Practitioners can use the noise impacts metric to assess the noise decibels resulting from road traffic.
