Collective Intelligence in Urban Design Areti Markopoulou The digital intelligence that is inevitably starting to penetrate every aspect of our previously analogue systems of living, working or social interacting calls for new models of designing our city and opens new territories of experimentation in the processes related to urban design. While the idea of intelligent machines that simulate “cognitive functions” such as “learning” or “problem solving” is not new, its extensive use, in recent years, in the urban design discipline opens up a series of new possibilities – as well as plenty of cultural, ethical or even aesthetic hesitations and risks. How do our cities learn? Can machines design and what? Is crowd intelligence appropriately harvested in our evolutionary and generative design processes?  And has our current big data analysis approach reached the limit of human and computational intelligence? Learning Cities explores the “intelligence” applied in the processes and outcomes of designing our urban environments.
