The document discusses the evolution of urban planning and governance in relation to information and communication technologies (ICT). It begins by looking at early 20th century visions of industrialized cities and advances in computing technology in the mid-20th century. It then examines how today's cities are increasingly shaped by data flows and information networks. The document proposes that ICT can help governing modern "information cities" through crowdsourcing data, increasing transparency of urban data, coordinating government bodies, and creating feedback loops for citizen actions. It provides several examples of projects using ICT for urban governance.
