Whether it is a flat place or a bumpy place, their highways and roads are always twists and turns. So many people have doubts that the construction of bending roads between cities is to avoid buildings and some parks, but in the wild, why still waste a lot of money to build a winding road? Today we will take you to understand why the curved road is built.

Anyone who has learned geometry knows such common sense, that is, the distance between the two points is the shortest. The highway built according to this principle can not only save a lot of costs but also shorten driving time and improve people's travel efficiency.

But this simple truth is almost no one executed. Because of the highway and wild roads are straight, many potential dangers will be caused.

The speed of cars driving on highways is basically stable in one range. In this case, the changes in the noise and vibration frequency in the car are relatively small, and the stimulation of the driver's sensory sense will be very small, so the driver will easily enter the fatigue driving mode.

Building the highway into a curved appearance can also greatly reduce the chance of a car accident because the emergence of the curve allows the driver to concentrate better and prevent the owner from driving a car accident due to fatigue driving.

The construction of highways is closely related to the terrain. Because highways are generally built in remote mountainous areas, they need to bypass or cross the mountain. However, it is still very difficult to make the highway through the mountain, so it is usually chosen to take a detour. This purpose is to avoid the mountains and reduce their impact on the mountain. So many curves will appear.

In addition, geological problems must be considered when building highways. Highways should bypass places where geological instability is to avoid collapse or deformation in the later period. Therefore, even if a relatively wide plain area, highways cannot be completely straight.

The following are the three techniques for driving at high speeds!

The risk coefficient of driving on highways at night will be much higher than during the day. The vision at night is not good. The most important thing is that at night, there may be many large trucks on the highway. These truck drivers may have fatigue driving, which will cause a lot of safety hazards.

During the high-speed driving process, you should try to drive at a constant speed, and sudden acceleration or deceleration will cause danger. Some people even said that suddenly parking on highways is the most dangerous action. The reason is obvious.

The speed of the car on the highway is very fast. If you stop suddenly, once the speed of the rear car is relatively fast, you cannot avoid it in time. Once the rear car hit our car, it will lead to a very serious accident.

Safe driving distances should change according to driving speed, weather, and road conditions. The faster the vehicle speed, the corresponding distance should be increased accordingly. Especially when the snow and rain, foggy days, or the road is freezing, the driving distance should be doubled.
