How do traffic lights time or decide when to display their colors (red/green/yellow)?
In: Technology
I know those here (Ontario, Canada) have camera/sensors that detect any traffic waiting for a green light. Especially during the night, if an intersection is not busy with no one waiting, you can see the pedestrian counter run down 3..2..1..and instead of creating a red light, it just resets to green since nobody is waiting.
At other lights, it’s fixed so even if nobody is there, it goes through the same process regardless; which I find annoying at night.
At night and at non-busy intersections, i feel should be flashing yellow lights on all intersections. Doesn’t waste everyone’s time, and gets the job done more efficiently
