Traffic signals as an important part of the traffic signal command, is the basic language of road traffic, for the promotion of smooth traffic, avoid traffic accidents play an important role. We usually see at the intersection of the signal is different, then they represent what it means, different types of traffic signals how to see?

First, the arrow points to the type of signal

Clearly indicate the direction of a traffic light, be sure to follow the provisions of the lane and the direction of travel, usually the intersection will also be set up to shoot the system, the behavior of breaking the light to be punished, very strict. Second, the full screen type signal light

This type of signal light is red and no clear instructions next to the sign can not turn right, the most right motor vehicle lanes do not affect the straight vehicles and crosswalk pedestrians through, and in the case of safety can be turned right, the other lanes are still in accordance with the “red light stop, green light,” the principle.

1, the intersection of the red light, vehicles (including bicycles, motorcycles, electric vehicles) can not go straight and left turn, arrow light right turn red light can not turn right, while the screen light red light and next to the sign does not prohibit right turn can turn right.

2, the intersection with the green light, according to the instructions of the direction of traffic, especially the direction of the arrow lights.

3, for the intersection of traffic light damage or the direction of the indication of the contradiction, there are traffic police on-site directing the vehicle traveling, according to the traffic police instructions to drive.

4, traffic light intersection crosswalk pedestrians have priority access to the principle, even if the vehicle can turn right must yield to pedestrians.

5, the traffic light interval is based on road conditions and traffic flow, generally speaking, the national highway is 30 seconds; city traffic is 10 seconds; fork in the crossroads is 15 seconds, fork in the crossroads is 10 seconds.

Third, full disk

Is a circle, inside the LED light source row full, people look like a round light, now this traffic signal is the road cited more.

Four, character pattern

The overall light into the shape of a character, the green light shows that people are walking or running, the red light shows that people stop there, the yellow light shows that the character moves slower, as a warning to people, light what lights, what to do.

Five, digital

The use of digital counting, inside the LED light source arranged in figures, with the changes in the controller and changes, this section is clearer, so that people look, they know how long to change the green light, how much time they have to pass through this intersection.

Different types of different patterns of traffic signals represent different meanings, some are bound motor vehicles, some are bound pedestrians, so as not to cause conflict, and can reduce traffic congestion at road intersections to ensure the safety of driving.
