   Adjusting the shutter angle affects the amount of time that film is exposed to light. A rotary disc shutter is a type of shutter. It is notably used in motion picture cameras. Rotary shutters are semicircular discs that spin in front of the film gate, alternately allowing light from the lens to strike the film, or blocking it.

   Cameras, microwave motion sensors, and radio-frequency identification (RFID) E-ZPass tag readers are used as inputs as a mean to for monitoring traffic flow. The data is fed through the government-dedicated broadband wireless infrastructure to the traffic management center to be used in adaptive traffic control of the traffic lights.

7. Smart traffic light - Wikipedia

   en.wikipedia.org/wiki/Smart_traffic_light

   Unlike other dynamic control signals that adjust the timing and phasing of lights according to limits that are set in controller programming, this system combines existing technology with artificial intelligence. The signals communicate with each other and adapt to changing traffic conditions to reduce the amount of time that cars spend idling.
