vehicle countdown timer traffic signal light
From the time we remembered, we often heard such a nursery rhyme: “Red light stops, green light
go”, this is also a familiar traffic rule in childhood, but most of he drivers in China have yellow light
on traffic lights. It is not clear how to drive during the period. The Road Traffic Safety Law of China
stipulates: “When the yellow light is on, the vehicles that have crossed the parking line can continue
This means that at the moment the intersection traffic signal light changes from green to yellow, the
vehicle that has crossed the parking line can continue to pass. the Vehicles that have not crossed the
parking line must stop before the parking line, otherwise it will violate the road traffic safety law. Will
That is to say, China’s road traffic safety law prohibits vehicles from passing through the parking line
during the yellow light.
Second, the pass rules for vehicle countdown timer traffic signal light:
Under the condition that the vehicle is prohibited from passing the parking line during the yellow light,
the meaning of the yellow light is basically the same as the meaning of the red light. The yellow light is
equivalent to the red light. The setting of the yellow light deviates from the purpose of reminding of the
driver. For a vehicle with a certain driving speed, there must be two stages from the driving state to the
stopping state, that is, the reaction time that the driver finds that the green light turns into a yellow light
and the required time from the driving speed to the stopping state after the braking measures are taken.
Braking time, the vehicle needs to travel a certain distance to complete from the driving state to the
Therefore, in the case where the yellow light is on the vehicle that is close to the parking line but has not
crossed the parking line, it is extremely easy to take emergency braking measures to stop in front of the
parking line if you want to comply with the road traffic safety law. This leads to the occurrence of rear-end
collisions, and does not guarantee that the vehicle will be able to park safely in front of the parking line.
Because of the inertia, the vehicle is often parked behind the parking line, so the yellow light is an inevitable
Third, the benefits of installing a vehicle countdown timer traffic signal light?
In order to reduce the suddenness of the traffic light from green light to yellow light, some cities add a green
light countdown to the end of the green light, so that the driver can predict in advance that the green light is
about to end, and the yellow light will be turned on immediately. Prepare for parking to reduce the occurrence
of yellow light.
However, the addition of a vehicle countdown timer traffic signal light to the driver before the yellow light is
turned on will have a great impact on the driver’s psychology and driving behavior. However, there is no in-depth
study in China yet, so the motor vehicle is added before the yellow light is turned on. The impact of the green light
countdown on traffic safety at intersections is not clear.
Fourth, the advantages of the vehicle countdown timer traffic signal light:
The vehicle countdown timer traffic signal light is a device attached to the existing urban traffic signal to count down
the remaining time of the green light signal as a reminder before the end of the green light signal.
Different cities have different time settings for the green light countdown timer. In some cities, and the green light
countdown starts when the green light is on. The countdown duration is the duration of the entire green light signal.
In some cities, the green light countdown starts a few seconds before the green light is about to end. If the green light
has 10 seconds left, the countdown starts.
