The growing concern about the disruptive effect of an adverse living environment on the health of the (Flemish) population has triggered the consortium to propose this project on measuring local environmental quality. There is an important need for more geographically detailed information at a reasonable price. Current measurement networks in Flanders cannot be used to measure the everyday exposure of the larger portion of the population. Ultra fine particle (UFP) and NOx concentration for example may vary considerably from street to street. Noise exposure has by nature an even much more localized effect. The scientific and technological challenge consists in creating more flexible and cheaper measurement and assessment methods for the (urban) living environment by making the system more intelligent and by optimally using a changeable distributed design.
