The sentence “stop at the red light, go at the green light” is clear to even kindergartens and primary school students, and clearly reflects the requirements of road traffic signal indication on vehicles and pedestrians. Its road traffic signal lamp is the basic language of road traffic, and the right of way of traffic flow in different directions can be adjusted by time and space separation. At the same time, it is also a road traffic safety facility to adjust the traffic flow of people and vehicles at the level intersection or road section, regulate the road traffic order and ensure traffic safety. So how can we predict the change cycle of road traffic signals when we are walking or driving?
A method for predicting a change period of a road traffic signal
Before prediction
It is necessary to observe the changes of road traffic signal lights in advance (if possible, see 2-3 signal lights) and continue to observe. While observing, you should also pay attention to the surrounding traffic conditions.
When forecasting
When the road traffic signal is observed from a distance, the cycle of the next signal change shall be predicted.
1. Green signal light is on
You may not be able to pass. You should be ready to slow down or stop at any time.
2. Yellow signal light is on
Determine whether to move forward or stop according to the distance and speed to the intersection.
3. Red signal light is on
When the red light is on, predict the time when it turns green. To control the appropriate speed.
The yellow area is the area where it is difficult to determine whether to move forward or stop. When passing through an intersection, you should always be aware of this area and make a correct judgment according to the speed and other conditions.
While waiting
In the process of waiting for the road traffic signal and the green light to go on, you should always pay attention to the signal lights on the front and side of the intersection and the dynamic situation of pedestrians and other vehicles.
Even if the green light is on, there may still be pedestrians and vehicles who do not pay attention to the road traffic signals on the crosswalk. Therefore, attention must be paid to when passing.
The above content is the method of predicting the change period of road traffic signal. By predicting the change period of the road traffic signal, we can better ensure our own safety.
