Smart Traffic Lights
With a combination of data fusion and simulation, and a considerable amount of knowledge about traffic signal controller operation, it is possible to predict how long the traffic signal controller will remain in red or green states.

Currently, government agencies and traffic signal owners are, strictly speaking, suppliers who have the access and permissions to use the traffic signal data and provide it to us citizens.
With a combination of data fusion and simulation, and a significant amount of knowledge about traffic signal controller operation, it is possible to predict how long the traffic signal controller will remain in the red or green state. Information about traffic signal controller performance and traffic demand, both long- and short-term, is stored and analyzed.
Finally, traffic signal information can also be used in the vehicle to control functions such as automatic stop-start. When a vehicle slows down and approaches a red light, the system can shut down the engine before the vehicle comes to a stop, further improving fuel efficiency.

Data packets that already communicate with traffic signal controllers are picked up and delivered every second, 24/7. The data then flows to a cloud-based data center where it is fed into algorithms and processes. Depending on the application, the output can be a prediction that tells drivers how long their red phase will last.
