Traffic lights manufacturers talk about traffic lights to optimize the passage effect is limited

"Lecture hall" interaction, represents the most caring signal optimization.

Who lives in south lake bag, "says Mr LuoShi Wen Xin south road street intersection, the peak three direction of the flow is very big, crossing it usually takes more than 20 minutes. Want to ask what to do.

From the riverbank traffic lights program of the civilian police, said control principle is according to the grades of road "convenience" mostly, guide the vehicle reasonable divergence, reasonable timing advance efficiency. Wuhan university of science and transportation expert professor cun-bao zhang said, adjust the signal timing does not work, dealing with questions, probably only have the effect of 10% to 20%. Optimizing the intersection traffic also need to the necessary road banned "left", "straight" ban, guide switching techniques such as cooperation.

This concept is in the north road residents du echoed. Orioles road, he says, in and out of the north road intersection to only allow "right into the right", in the north main street at most, only need will be able to pass a signal cycle, and often have to wait two or three previous signal cycle.

Why turn lights countdown to 9 seconds

Why the countdown traffic light changes were set to 9 seconds? This is an interesting question. Police introduction, light gb "countdown", there is no rule necessary light intelligent control system based on intersection automatic detection of traffic dynamic adjust the signal timing, so cannot guess the countdown time length. For dealing with the opposite, wuhan traffic scientific research personnel through the past research, finally found "appeared in the countdown to 9 seconds" indigenous method, is the domestic first appeared in intelligent control system with the countdown. Practice shows that the practical and useful。
