Abide by traffic regulations Harbin Institute of Technology has a paper "Cause Analysis and Preventive Countermeasures of Expressway Rear-end Accidents", which analyzes the inducing factors of rear-end accidents.
It divides the inducing factors of high-speed rear-end collision into human factors and vehicle factors. Among them, what are the human factors?
9 factors: speeding, fatigue driving, drunk driving, overloaded trucks, overcrowded buses, overtaking illegally, failing to keep a safe distance, changing lanes illegally, and improper braking.
Eight if the law requires it.
Therefore, to avoid rear-end collision, it is most important to abide by traffic laws.
For example, the road is slippery on rainy days, and many people wrestle. Although there are many reasons for wrestling, almost all of them are related to the wet ground.
If you change a pair of non-slip shoes and walk carefully, you can prevent yourself from falling to a great extent.
If you miss the exit, don't slow down at will. "Oh, I missed it." You don't do this; Don't stop; Don't bang or reverse it.
These can prevent being rear-ended by other cars to a certain extent.
Besides, if you mess around like this, you will lose points and revoke your driver's license and so on.
Pay more attention to the rearview mirror. In addition, pay more attention to the rearview mirror when driving.
The rearview mirror can be used not only to observe whether there is a car behind, but also to roughly judge the distance between the car behind and us.
This is mainly because the imaging size of the rear car in the rearview mirror is directly related to the distance.
There is a paper in Highway and Automobile Transportation magazine, which studies a new type of safe lane-changing rearview mirror based on frame marking technology, and gives the data of a domestic brand car as a reference.
For example, when the size of the rear car on the rearview mirror is 10mm, it means that it is only about 50m away from us.
Of course, they are exaggerating. They have worked it out, so it's probably no problem for us to refer to it.
Moreover, the "Regulations on the Implementation of the Road Traffic Safety Law" also stipulates the safety of vehicle distance: when a motor vehicle is driving on an expressway, the minimum vehicle distance must be kept above 50m.
In other words: the rear car is in the rearview mirror. When you see it is almost as big as a fingernail, you should pay attention. How big are the nails?
When the other party is too close to the car, you can distance yourself while ensuring safety.
Or simply let the other person go first, especially when the navigation prompts that there will be traffic jam ahead, and it is possible to brake, he will go first, and he will go first.
Flexible use of lighting, then flexible use of lighting may also reduce the risk of being rear-ended. In fact, some cars on the market have been equipped with emergency braking warning systems.
Through the acceleration sensor and the brake pedal sensor, the system will judge that the car is braking urgently.
At a fixed frequency, the brake lights or danger warning flashes intermittently to warn the cars behind.
There is a paper in the Journal of Electronic Design Engineering, which is mentioned in the Design of Automobile Brake Lamp Controller Based on Acceleration.
Compared with the traditional normally-on brake light, the driver's response can be shortened by 0.2s.
Don't underestimate 0.2s at high speed, and the braking distance is shortened by about 4 to 5m. What is the concept of 4 to 5m? The length of a car, okay?
If we drive and there is a sudden traffic jam ahead, we need to significantly reduce the speed, or we can turn on the danger warning flash in advance, which is called "double flash" in the local dialect.
We don't want to stop at the finish line. We can brake gently again and again.
This is not because our car is old and can't stop, but because the car behind us sees: "Oh dear", the brake lights keep flashing and the double flashing lights are flashing. Give the rear car a warning to slow down.
Otherwise, we stopped, it didn't stop, it didn't hit? Right? Also remind the car behind.
Look at the speedometer. Finally, look at the speedometer and calibrate the actual speed with your estimated speed, which also helps.
Chang 'an University has a paper "Research on Automobile Rear-end Collision Prevention System on Expressway".
The driver's mastery of the speed mainly depends on two aspects: one is to look at the odometer, is that what the odometer says? The other is based on personal subjective feelings.
Subjective feeling is that the driver judges the speed according to the movement of the surrounding scenery and the feeling of the body, as well as the wind he hears. Of course there will be errors, right?
The longer the driving time, the greater the error between the speed judged by our driver and the actual speed, which is called "speed adaptability".
It's like: Your girlfriend asks you what time it is. If you just looked at your mobile phone not long ago, you can estimate the time, which is more accurate.
You haven't seen your cell phone for a long time. Long time no see. She asked you what time it was. Maybe you can't tell 4 o'clock from 8 o'clock. It's a far cry.
This deviation in speed estimation may lead to rear-end collision.
For example, if you find that the speed exceeds the forecast too much, you will suddenly brake in case of accidents such as speed measurement, right?
As soon as you braked, how did the people behind you know that you braked because of this? If you "pia", you may bump into it.
Therefore, if the car has no cruise function, it is necessary to always look at the speedometer to calibrate the speed deviation.
Not to repair this watch, but to calibrate the cognition in our minds and the deviation on this watch.
To avoid being rear-ended, you must obey the traffic laws and pay attention to driving. So in general, if you want to avoid being rear-ended at high speed, you must obey the traffic rules.
Secondly, pay more attention to other driving information, including rearview mirrors and dashboards.
And try to remind the following vehicles in advance with lights when emergency deceleration is needed. I think it's good for everyone.
