In Germany, most highways are speed-free. The country that built the expressway in the world, with 11,000 kilometers of expressway, is the fourth-largest expressway network in the world after China, the United States and Canada, and about 62% of the roads are open-speed sections. .
First of all, we can analyze from the construction standards of German highways, to ensure that cars can travel at a safe speed, then the highways must have strict construction standards. In order to avoid the potential threat caused by excessive slope, they require that the high-speed road can not be more than 4 degrees of slope, and the road is made of concrete with a thickness of more than 80cm, which is rare in the world.
At the same time, the German highway has a full range of security monitoring, road temperature, vibration, day wind speed, rain and snow monitoring throughout the day, high-speed signage and signal lights are computer-controlled, when traffic does not occur In the case of smooth conditions, the instructions will be adjusted according to the road conditions.
Of course, due to the considerable development of German industry, the German automobile production line is also very mature. Compared with other countries, Germany has placed more emphasis on the safety and stability requirements of automobiles. It is said that German cars will not feel very fast when they drive to 200km/h, and the wheels are tightly gripped on the ground. It makes people feel very stable.
Moreover, it is said that Germany is one of the most difficult countries to test drivers in the world, and the driving school pays attention to the cultivation of driving standards and humanization. Many details have become the focus of the German driver’s license test, such as changing lanes and overtaking. Head, turn to turn to confirm the road conditions and so on.
The Germans have always been rigorous and abide by the rules, while the German population and area are in a controlled range, providing a suitable environment for high speed and speed. Compared with Germany, most countries have to face more complicated road conditions and a wider variety of models. Therefore, for safety reasons, most countries limit the maximum speed to 130km/h.
