Are university campuses turning into mini smart cities?

Think of a university campus: it has its own roads, shops, residential areas, banks and transport links. It may be visited by tens of thousands of people each day. It is, in effect, a tiny city. Across the globe, these mini metropolises are increasingly opting for a smart city approach. This is a tech-driven model that's used in places such as Barcelona, where street lamps react intelligently to surroundings to save energy; Seattle, where smart traffic lights respond to the conditions on the road; and even Milton Keynes, which has a real-time "data hub" sharing information about the town's energy and water consumption, transport, weather and pollution.
