TRaffic model for better Air Quality policies in cities

Assessing the impact of measures on local traffic emissions through the use of online tools, while investigating what can be the role of citizens in the development and implementation of these measures. 

According to the World Health Organization (WHO), air pollution is the biggest environmental health risk in Europe. CityTRAQ focusses on air pollution caused by traffic emissions. The project aims at developing two tools: a screening and a scenario tool. The screening tool will make it easier to identify hotspots of air pollution in cities; the scenario tool should show the effect of measures on air quality. The cities of Antwerp, Bruges and Ghent run pilot projects, in which these tools will be put into practice. Besides measuring traffic emissions and testing the online tool, the project also focusses on the participation of citizens. The project investigates how citizens may contribute to developing solutions for improving air quality and policy-making. 


CityTRAQ aims to:

  • Develop a screening and scenario tool to provide insight into traffic emissions and the impact of measures to improve air quality
  • Include citizens in policy-making and the development of measures to improve air quality


CityTRAQ is a cooperation of the Flanders Environment Agency (VMM), the City of Antwerp, the City of Bruges, the City of Ghent, the Croatian Meteorological and Hydrological Service (DHMZ) and RIVM.

RIVM role

RIVM provides expertise on air quality measurements using sensors and methods to calibrate these measurements. Furthermore, RIVM is part of the coordination group of CityTRAQ. Hester Volten and Amber Woutersen represent RIVM in CityTRAQ's coordination group.
