Screen highlighting buses and pedestrians

The Massachusetts Institute of Technology has teamed up with Telecom Italia on a real-time mapping system that tracks how people move in urban spaces. The project, known as Real Time Rome, made its debut Friday at the 10th International Architecture Exhibition at the Venice Biennale. The technology maps real-time data gathered from mobile operators and transportation authorities. This projection screen shows buses in yellow, while the red represents the density of people.
