Intelligent Cities is an initiative of the National Building Museum, with the support of TIME and IBM and funded by The Rockefeller Foundation. More of us than ever now live in cities. The Intelligent Cities Initiative “explores the intersection of information technology and urban design to understand where we are, where we want to be, and how to get there.” For example, they look at the relationship between space, time, and money when it comes to car ownership and find that if a city could reduce car ownership by 15,000 cars, that city would see a return of $127,275,000 to their local economy (and of course, thousands of dollars saved by the individual citydweller).
