How do traffic lights work Singapore?
The GLIDE system links the traffic signals at adjacent junctions along the major corridors, by coordinating the start of their green times. This allows motorists to catch the “green wave” and travel from one junction to another without having to stop at the red lights as often.
How are traffic lights controlled?
The traffic demands are registered through the detection installed either in the carriageway or above the signal heads. The controller then processes these demands and allocates the green time in the most appropriate way. Minimum and maximum green times are specified in the controller and cannot be violated.
Are traffic lights controlled by AI?
Thanks to an artificial intelligence algorithm, traffic lights are capable of adapting to traffic, instead of the other way around. Additionally, as with every machine learning system, the traffic lights can learn from their environment and optimize their operations more and more.
Do all traffic lights have cameras Singapore?

Why do we need smart traffic lights?
A major use of Smart traffic lights could be as part of public transport systems. The signals can be set up to sense the approach of buses or trams and change the signals in their favour, thus improving the speed and efficiency of sustainable transport modes.
