The DUET project was first presented to the Flemish cities and municipalities on 24 June, 2022, during the user day "open data and geodata" of Digital Flanders.
Lieven Raes and Gert Vervaet showed how different models of traffic, air quality and noise interact in Ghent (Belgium), Pilzen (Czech Republic) and Athens (Greece). They pointed out that to get good interactions and reliable simulations, the quality of data is vital.
There was a great deal of interest in the architecture and reusability of the DUET components.
