What is the green band of LED traffic lights?

Through the introduction of the previous article, I believe that everyone has a certain understanding of traffic lights and solar LED traffic lights. Xiaobian read the news and found that many users are puzzled and puzzled about what the green band of LED traffic lights is and what it does. For this reason, the editor specially organized the information about this part, and then briefly explained it for you:

1.The meaning of green band
The green wave belt is when the speed of the road section is specified on the designated traffic line, and the LED traffic signal is required to adjust the green light starting time of each intersection passed by the traffic flow according to the distance of the road section. At each intersection, we just met a “green light”.

2.To realize the green wave band, the following two points must be achieved: a common period and a unified clock. (2) To realize the green wave band, the following two points must be achieved: a common period and a unified clock.
(1) For intersections with a large common period, the signal period calculated by signal timing is taken as the common period of all intersections. Therefore, in general, the signal cycle of intersections with small traffic capacity is long, and other intersections will not be congested after this cycle is used as the cycle for all intersections.
(2) Unified clock

All intersections run their respective phase timing schemes according to a time reference to ensure the accuracy of the phase difference of the LED traffic light signals coordinated between intersections, without time drift and scheme misalignment; due to the clock in each signal controller Time drift coordination will fail due to different clock accuracy and other reasons. Therefore, a master controller should be set in several intersection signal controllers that need to be coordinated to perform unified time reporting.

The above is all the content about the green wave band of LED traffic lights compiled by the editor. I hope that the article of the editor can effectively help you solve your problems in the future!
