Embodiment Construction
[0005] The present invention is a main road priority signal light, and two monitoring points are installed on the designed secondary road at two meters and 20 meters away from the stop line. Usually, the green light of the main road is guaranteed to be released for a long time, so as to increase the passing speed of vehicles. When vehicles are detected at both monitoring points on the secondary road, the secondary road will be given a green light for 30 seconds. When there is only one monitoring point on the road to detect the vehicle, the green light will be given to the road for ten seconds after two minutes. The main road priority signal lamp of the invention has a simple production process and is easy to popularize.

The invention relates to a main road priority signal light. Two monitoring points are installed in the positions, two meters and several meters away from a parking line, on a secondary rod, the green light on a main road is always on at ordinary times, and the pass rate of vehicles is improved. When the two monitoring points on the secondary roads both detect that vehicles exist, the green light on the secondary road is on for a period of time. When only one monitoring point detects that vehicles exist, the green light on the secondary rod is on for more than ten seconds after several minutes. The main road priority signal light is simple in production process and convenient to popularize.
Description
technical field [0001] The invention relates to a signal lamp, in particular to a main road priority signal lamp. Background technique [0002] With the improvement of people's living standards, more and more people own private cars. Road congestion is getting worse. Existing signal lamps execute the release vehicle according to the procedure. I often see this phenomenon, the main road has a red light, and vehicles are lined up in a large group. The next green light, but no traffic. It is a waste of road resources, and the driver who looks at the other side's road without cars because the red light cannot pass is very uncomfortable. Contents of the invention [0003] The present invention is a main road priority signal light, and two monitoring points are installed on the secondary road at two meters and several meters away from the stop line. Usually, the green light of the main road is guaranteed to be released for a long time, so as to increase the passing speed o...
