City of Systems: Traffic Signals
Video on New York City’s Traffic Management Center (TMC) which monitors and controls half of the city’s 12,400 traffic signals.
Vodpod videos no longer available.
At the TMC, computers and live video feeds monitor real-time data — including current signal displays, traffic detectors and cycle lengths — at hundreds of intersections each. Coaxial cables connect these computers to the intersections, and 238 cameras allow the engineers to observe and adjust signal timing in case of an accident or other sudden change to the flow of traffic.
This Urban Omnibus video is the first in a series called City of Systems, a suite of short videos intended to offer a poetic peek behind the scenes of some of the complex systems that enable New York City to function.
