After driving for so many years, some people may be curious, why china's high-speed driving speed limit is 120, in fact, the reason why this setting is also a special scientific basis, then some people will be curious, with the current level of science and technology, the performance of the car is getting higher and higher, why the highway can not speed up, or to limit the speed of 120?
Now let me explain to you from three aspects.
First, the speed limit of 120 hours is formulated by the state for comprehensive consideration of safety and efficiency
Since most of the highways in our country are now asphalt paved, after professional testing by professionals, the safest limit for cars to drive at high speeds is 120. In addition, taking into account the driving efficiency and utilization rate of the highway, it is recommended that the maximum speed limit of 120 is also a very reasonable driving efficiency.
Second, practice shows that if the high-speed speed exceeds 120 per hour, the stability of the car will decrease
Car control stability and high-speed speed inversely proportional, the higher the high speed, the car's control stability will decline, on the contrary, the lower the high speed, the higher the control stability of the car, coupled with the background of this era, most people are fast-paced life, so there will be many people will choose to drive at night.
Most of the night driving will rely on street lights to drive, at this time, if the speed is too fast, if the front suddenly breaks into something, the driver simply can not brake, which is often the cause of the scene of the car accident.
Then there are a lot of natural resources in China, nature protected animals and nature reserves, but the road has to be opened, so some places of the highway is set up near the nature reserve, the most famous is in 2003, one of the national key highways of the Sixiao Expressway, this is through the Xishuangbanna wildlife sanctuary, including the Wild Elephant Valley.
At this time, if the maximum speed limit is not set safely and stably, it may pose a threat to the local biodiversity, so it was decided to set the maximum speed limit of the expressway to 120 out of comprehensive and multi-faceted considerations.
Third, there are many novices on the road, and for safety reasons, the high-speed speed must not exceed 120 per hour
Although so much has been said, there will still be many people who express too much understanding, but some people who have gone abroad know that in the developed countries such as France and Germany, the high speed of their countries is very high, especially Germany, some parts of their country are still not limited to speed, but these are based on the actual situation of the country.
At present, China's domestic automobiles are inferior to Europe in terms of quality control, especially germany with high standards, coupled with the population density of our country, and the use of land is more, so the highway is generally narrower, so the width of the highway pavement in our country is compared with the width of the highway pavement in their country.
Another reason is that the German driver's license pass rate is extremely low, and our country is obviously different, up to the sixty-year-old people down to the young people who have just reached the age of eighteen can take the driver's license, and our country's driver's license pass rate is also relatively high, the average pass rate of the first and fourth tests of the driver's license test is 90%, the pass rate of subject two is 70%, and the pass rate of subject three is 60%, which means that there will be many novices every year.
Therefore, in summary, at present, our country's high-speed speed of 120 per hour is the maximum speed, coupled with the current domestic automobile overall industrial level compared with some developed countries is still relatively backward, so the high-speed speed limit to 120 hours is also for safety considerations.
After reading these, you can understand why the top speed of our national highway is still 120 per hour for so many years, after all, it is still necessary to drive safely, remember that there are thousands of roads, and safety is the first!
