The Action will develop a service that combines data on air quality, weather conditions, and traffic flows in order to allow citizens and municipalities to estimate the level of pollution resulting from varying traffic flow conditions.

The service will be deployed in several European cities. Related datasets (including metadata) will be published on portals harvested by the European Data Portal.

Specifically, the Action will:

  • Define a standard set of metadata representing urban air quality maps
  • Provide citizens and public administrations with a real-time map of the estimated levels of pollution in the urban areas based on data from air quality sensors, and measurements of standard air quality stations
  • Develop of a service to predict urban air quality based on the data collected, weather forecasts and traffic flows. This service will make use of High-Performance Computing (HPC) technologies to estimate the diffusion of pollutants in the urban areas. New hypothesis of circulation, such as changes in the urban fleet of vehicles, increase of low emission vehicles, and impacts on air quality will be simulated as well.
  • Publish an open dataset describing the urban air quality maps and the prediction maps of the 6 cities in which the service will run for the duration of the Action.
