After the newer generations of traffic signals that use LED lights which consume 85-90% less energy, it is now possible to incorporate battery backups into the traffic light systems. The battery backups would be installed in the traffic controller cabinet or in their own cabinet adjacent to the controller.
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.

Some companies also offer software with which the street lights can be monitored and managed wirelessly. Clients, or other companies, can access the software from a computer, or even a tablet. From this software, they can gather data, pre-set levels of brightness and dimming time; receive warning signals when a light defects. [9] [10] [11] [12]
Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. [1] They can form part of a bigger intelligent transport system.
For solenoid-operated accessories (e.g. points, mechanical signals) or accessories involving lights (e.g. colour light signals), track-powered accessory decoder modules, each providing four outputs, were available. Each output could be configured either for burst operation or continuous output, for use with solenoids or lights respectively.
For example, in a smart light setup, one participant thought that her iPad communicated directly with the light, telling it to either turn-off or on. [37] In reality, the iPad sends a signal to the cloud system that the company uses (in this case, the Hue Bridge) which then signals directly to the device.
InSync adaptive traffic control system is a real-time adaptive traffic control system that enables traffic signals to immediately adapt to traffic demand. MASSTR (Meadowlands Adaptive Signal System for Traffic Reduction) located in the Meadowlands Region of northern New Jersey will incorporate over 128 signals when complete. As of June 2013 ...
