AirGIS: a GIS-based modelling system for estimation of traffic-related air quality and human exposure

AirGIS is a human exposure modelling system for traffic air pollution. It was developed for application in Danish air pollution epidemiological studies, human exposure studies, as well as urban air quality assessment and management. It has been developed by the National Environmental Research Institute in Denmark.

One of the unique features of AirGIS is that it is able to generate street configuration and traffic data for the OSPM model based on digital maps and national databases. This enables estimation of air quality levels at a large number of addresses in an automatic and effective way.

The modelling system was applied in a number of Danish epidemiological studies that involve exposure calculations at more than 200,000 addresses in Denmark or about one tenth of all addresses in Denmark. (Projekt AIRPOLIFE) The model system allows for exposure estimates at a high spatial resolution (address level) and a high time resolution (hour). The system integrates air pollution dispersion models, digital maps, national and local administrative databases, concentrations of air pollutants at regional, urban background and street level, meteorological data, and a Geographic Information System (GIS). The system uses the Danish Operational Street Pollution Model (OSPM), digital maps on roads with traffic data, buildings with building height data and geocoded addresses of study subjects, and it applies ArcView 3.x.
