It depends on which traffic lights, in the surrounding area, pedestrian spots in cities, for example to cross street tracks, safely in the five-digit area. Street lights switching yes in the cycle green yellow red/green. If you calculate them individually the same.
You can calculate it yourself. Watch a specific light and you know how long the individual phases last. You don't need more information to do the bill.
You can easily determine this – put on a traffic light and measure the seconds between turn on red and turn on red again.
And you write that second number!
Then you divide 86400 by this written number of seconds!
And you have the result how often the traffic lights turn on red the day!
On average about 640 cycles per day.
2000 times.
