Reaction distance, brake distanceReaction distance refers to the distance the vehicle traveled within the driver's reaction time, including the brake reaction time (from the discovery of the stimulus to the movement of the foot to the brake pedal), the brake action time (from the start of the brake pedal to the maximum braking force), and the continuous braking time (from the maximum braking force to the car stopping).
Braking distance referred to the distance traveled by a vehicle from the beginning of braking to the complete standstill of the vehicle when the vehicle was moving at a certain speed. It was the distance traveled by the vehicle from the moment the driver stepped on the brake pedal to the moment the vehicle came to a complete stop at a certain initial speed. It included reaction distance and braking distance. The smaller the braking distance, the better the braking performance of the car.
The length of the reaction distance depended on the driving speed and reaction time. The higher the driving speed or the longer the reaction time, the longer the reaction distance. The reaction time was directly related to the driver's sensitivity and technical proficiency. Usually, the reaction time was 0.75 to 1 second. For example, when the driving speed was 30 km/h and the reaction time was 1 second, the reaction distance was 8.33 meters.
The length of the braking distance was related to the driving speed, the braking force, and the friction coefficient. The higher the driving speed, the longer the braking distance. The driving speed was proportional to the square of the braking distance. The calculation method (commonly used internationally) was: Braking distance = vehicle speed/10 * 3+ vehicle speed/10 * vehicle speed/10, but there would be differences if the tires were different (such as summer tires and winter tires) or the road conditions were different.

Safety distance, braking distance, reaction distance, subject oneIn subject one, stopping sight distance included reaction distance, stopping distance, and safety distance. Reaction distance refers to the distance that the car travels from the moment the driver finds an obstacle in front of him and decides to take braking measures to the moment the brakes really start to work. Braking distance refers to the distance from the moment the brakes take effect to the moment the car comes to a complete stop. The safe distance (in the concept of stopping sight distance) was the minimum safe distance that should be maintained between a car and an obstacle after it had completely stopped.
For example, in some scenarios, the safety distance was stipulated: on the highway, when the speed was lower than 100 km/h, a safety distance of more than 50 meters should be maintained from the car in front; when the speed was higher than 100 km/h, a safety distance of more than 100 meters should be maintained from the car in front; when the speed was equal to 100 km/h, the minimum horizontal distance was 1.5 meters, the safety distance was 100 meters, and the dangerous distance was 50 meters. Also, in low visibility weather conditions, when the visibility is less than 200 meters, the speed should not exceed 60 km/h, and the distance between the car in front of the same lane should be at least 100 meters; when the visibility is less than 50 meters, it should leave the highway.

What is the difference between the braking distance, the reaction distance, and the safety distance?Braking distance refers to the distance traveled by the vehicle when the vehicle is at a certain speed. It is one of the key parameters to measure the braking performance of the vehicle, including the reaction distance and the braking distance.
The reaction distance referred to the distance the vehicle traveled within the driver's reaction time. The reaction time here included the brake reaction time (from the discovery of the stimulus to the movement of the foot to the brake pedal), the brake action time (from the start of the brake pedal to the maximum braking force), and the continuous braking time (from the maximum braking force to the car stopping).
The safe distance refers to the necessary distance between the rear vehicle and the front vehicle to avoid accidental collisions. Its accurate measurement depends on the braking distance, but it also takes into account the driver's reaction time. Different driving speeds, weather conditions, types of vehicles, and road conditions had different requirements for the safe distance.

I chose to be strongThe following is an example of an essay on "I chose to be strong":
I chose to be strong.
Life was like an ever-changing ocean, sometimes calm and sometimes turbulent. In this long journey of life, we will all face countless challenges and difficulties, and I, after experiencing many storms, firmly chose to be strong.
In the long river of memories, there was an unforgettable experience. It was a winter day, and the gray sky seemed to indicate the arrival of misfortune. When I learned that Grandma had cancer, my world seemed to collapse in an instant. I was like a bird lost in the dark, at a loss, tears uncontrollably flowing out of my eyes. When I saw Grandma being tortured by her illness on the hospital bed, the warm images of her cooking for us and taking care of us in the past kept appearing in my mind. My heart ached as if it was being torn apart, and tears flowed freely.
The moment Grandma left, my sadness drowned me like a surging tide. However, in my endless grief, I gradually realized that immersing myself in grief would not change the situation. Life will not stop because of my weakness. The world around me is still moving. I understood that I couldn't continue to be weak like this. I had to change, so I chose to be strong.
Becoming strong was not an easy feat. It was a long and difficult process. It was like learning to ride a bicycle. At first, I was full of longing and couldn't wait to learn it. However, after falling over and over again, the pain and frustration kept coming. For a moment, I wanted to give up and escape this pain. But there was a voice in my heart that told me that if I gave up now, I would never be able to ride freely like those skilled riders. Thus, I gritted my teeth and endured the tears and pain. I got up from the ground again and again and continued to try. Every time I stand up again after falling, it is a step towards becoming stronger.
On the road of growth, whether it was the pressure of academics, the troubles of interpersonal relationships, or the various disappointments in life, I told myself to be strong. Because I know that running away and being weak will only make the problem more complicated. Only by facing it with strength can I find a way out of the predicament. Just like me who was lost in a dark underground garage. Although I was afraid and anxious, as long as I didn't give up looking for the exit, as long as I kept trying with firm faith, I would eventually be able to see the sun again.
Now, I have learned to turn pain into motivation, and tears into the source of inner tenacity. I chose to be strong because I knew that only by being strong could I move forward bravely on this challenging road of life, realize my dreams, and welcome a beautiful future.
