The role of traffic lights in the traffic field

The development of the transportation field is now getting faster and faster, and traffic lights are an important guarantee for our daily travel. Hebei signal light manufacturer introduces that it is an indispensable equipment in today’s traffic field. We can see traffic lights on almost every road. They are set at the intersection of two or more roads, so that vehicles and pedestrians can be in order. The driving can allow everyone to pass the road according to the instructions of the traffic lights.

If there is no traffic signal light, the traffic system will be paralyzed, and there will be no rules for passing vehicles and pedestrians, causing confusion and hazards. Correct use of traffic signal lights can also greatly reduce the workload of traffic police and save labor costs. It can also improve the travel of vehicles and pedestrians. Traffic signal lamp suppliers have become an indispensable part of our daily life.

The power consumption of the traffic signal light is small, the current passing through is very small but it can emit a very large light, which not only saves power resources but also facilitates drivers, pedestrians and drivers. It is very long. A normal traffic signal light can generally be used for more than 100,000 hours. It is very durable and can reduce cost and manpower. The inclined surface design of the surface of the light-transmitting lens makes the surface of the traffic signal light not easy to accumulate dust and can be used for a long time. The brightness will not be affected by dust accumulation.

The shell also has a good waterproof and dustproof function, and has good flame retardancy, which can greatly improve the service life and quality of use of traffic lights, and ensure the normal and long-term use of the traffic system. For three-fork intersections, the coordination of turning left, going straight, and turning right at the entire intersection should be fully considered when setting the phase of traffic lights.

At present, in many cities, three-phase control is adopted for the signal lights at three-crossing intersections. This control method brings great hidden dangers to pedestrians crossing the street, and the traffic order of the entire intersection is disordered, and accidents are prone to occur. Such issues are not covered in the current regulations and standards.
