From the working principle of electronic police: where is the red light crossing and stopping? Can you back up?

Whether intentionally or not , A few people may have the experience of driving through a red light , Of course, we can find many reasons , For example, poor vision 、 The road markings are not clear 、 Traffic lights don't show time, etc . ok , We are not going to make complaints about traffic design , It's about the principle of shooting when running a red light .

The picture above is a picture of standard violation , This picture is composed of three pictures , One of them is a detailed picture of the license plate . It is not difficult to see from the position of the three pictures , This is through the intersection of three positions , Photos taken separately , The principle is shown in the figure below .

The intersection is red , Gather photos from three locations , There is no doubt that you ran the red light . In case , As long as the trigger system takes photos of two positions , You don't have to run a red light , Why not ? To make this clear, we must start with the relevant laws and standards .

How to define running a red light ?

Issued by the Ministry of public security GA/T 496-2014《 General conditions for automatic recording system for running red lights 》 Regulations , The automatic recording system for red light running shall be able to record at least the following 3 A picture reflecting the process of running a red light .

(a) Pictures that can reflect that the motor vehicle has not reached the stop line , And can clearly identify the vehicle type 、 Traffic lights are red 、 Stop line ;

(b) A picture showing that the motor vehicle has crossed the stop line , And can clearly identify the vehicle type 、 Number plate number 、 Traffic lights are red 、 Stop line ;

(c) Can reflect motor vehicles and (b) In the picture, the motor vehicle moves forward , And can clearly identify the vehicle type 、 Traffic lights are red 、 Stop line .

If you cross the stop line , Stop at the zebra crossing , In theory, it's impossible to take a third picture (c). Therefore, there is such an explanation in the traffic safety training , For entering the parking line after the red light is on , But don't drive forward , Vehicles moving forward only after the green light is on will not be regarded as illegal records .

Curious people will want to ask , Where is the farthest stop after crossing the stop line , Like in the middle of an intersection . The difficulty lies in the distance across the stop line , Because the regulations do not specify , This adds some free space to the system decision .

There is a background interface of running a red light and recording system on the Internet , The yellow line in the picture It's the third picture (c) Trigger line , Almost to the zebra crossing across the street .

however , The so-called third photo trigger line logic doesn't make sense , Why? ? If a bus 、 truck 、 Semi Trailer , To avoid running a red light, stop the car on the so-called trigger line , That won't block the whole road ? If you can avoid punishment , It has long been drilled by the old driver .

I checked 《 Road traffic safety illegal act handling procedure stipulation 》, It clearly stipulates that , Records of illegal acts collected by traffic technology monitoring equipment , It shall be reviewed by the traffic management department , Can be entered into the road traffic violation information management system , In other words, it must be reviewed manually . This is the case of receiving violation information a week later , From a technical point of view , Running a red light can receive violation information every second .

Where do you go when you run a red light , To put it bluntly, it depends on how the audit personnel determine , The so-called third photo trigger line , There is no regulatory or standard basis .

Reversing back across the stop line is exempt from punishment ?

Some smart friends will ask , If you cross the stop line , Will reversing back avoid punishment , In fact, not many people have done this .

But from the information circulating on the Internet , Reversing is not only not exempt from punishment , And there will be an additional “ astern ” Violation of regulations . Crossed the stop line , Just stop there , Don't be smart, back up .

At the end

When the rear of the car crosses the stop line , I've been able to take a second picture , And when the back of the car crosses the zebra crossing , You can take a third picture . As for after taking three photos , Will you be punished , It also depends on the auditor's determination of the behavior of running the red light .
