What do I need to check when I enter the entrance of Hefei Expressway?

The entrance of Hefei Expressway needs to be inspected, including driver's license, whether the drivers and passengers wear seat belts, whether there is overload behavior, whether the violation of expressway is handled, and whether fire extinguishers and triangle warning signs are equipped. At present, most places still rely on manual inspection by traffic police. In more advanced places, there will be cameras and X-ray scanning equipment to detect foreign bodies.

Background of high-speed construction

As a symbol of modern traffic, the highway was born not because of the needs of social economy, but because of the requirements of war. In 1930s, Germany launched World War II. In order to implement the blitzkrieg strategy, it built a 3,900-kilometer multi-lane expressway. As soon as the expressway appeared, it played a huge role.

At that time, the commander-in-chief of the French army thought that it would take three days for the Germans to reach the attack site at the earliest, but it took only one day for the Germans to reach the front line with the rapid traffic on the expressway. After bypassing maginot line, the French army collapsed instantly. After World War II, the developed countries led by the United States set off a climax of expressway construction, and the western developed countries represented by the United States rose.

In the 1980s, when the developed countries in the world were considering the construction of trans-regional and transnational expressway networks, most people in Chinese mainland still could not understand the concept of "fully enclosed and fully interconnected expressway" and were used to the traditional concept of "everyone has a car on the road, and everyone has a boat on the water".
