The 5 technologies that are going to define the next decade in cities

Colin O'Donnell is the chief innovation officer of Intersection. Cities have always been hubs of technological experimentation, shaped by the people who inhabit them and the tools they use. We can still see the marks, both charming and garish, from technologies of years past -- from old aqueducts to telephone booths to the damage done by cars. The next wave of real-time technologies that will define the next decade are software (rather than hardware) upgrades to the city that will nonetheless transform the way we work, play and live in our physical environments -- our "brick and mortar" cities. And these technologies, each transformative in their own right, when used in combination to develop new products and experiences, will have a multiplying effect on the rate of change we see in urban environments.
