Milestone projects are one of the primary activities to achieve the DTCC vision. They stipulate the centre’s strategic direction and research agenda and are a visible driver for the overall centre. The milestone projects facilitate cutting-edge research and create innovations that contribute to creating great societal value in the development and use of city-scale Digital Twins. Milestone projects reach across different Research Areas and involve several centre partners. A milestone project will be funded for minimum 2 years and maximum 4 years.
