Not many cars slow down domestic traffic, experts: no one can move these “three big mountains”
Currently, people cannot work without vehicles. Most people choose public transportation such as subway, but most people choose self-driving as self-traveling is most convenient and very convenient. In addition, many people also choose to drive themselves when they travel and they can take some luggage with them.
Add more fun and convenience to your journey. Our economic development has made it possible for people to own their own cars, expensive or cheap, they are mostly affordable, so we can see a lot of cars on roads.

In addition, people who have watched movie are very familiar with plot, that is, main character "囧囧" is driving through streets of Thailand. He feels that traffic in Thailand is very busy, but words of Thai driver leave people speechless, he said that there are even more traffic jams in Beijing.
Congestion is a very important social problem affecting most developed and some developing countries. We also have this situation in hot spots of Chinese cities. Every time I get stuck on road, I feel very irritable, everyone thinks why there is such a traffic jam, is it really because there are too many cars?

Despite fact that people are constantly producing and using vehicles, more and more roads are being built. Why is situation with vehicle congestion becoming more and more serious?
Actually, there are several very important reasons. Our country has its own situation and its own reasons. The most important reasons are following.

The first reason is historical reason for planning and using roads.
We never thought that China's technology and economy would explode to such an extent, and no one expected that popularity of cars in China would be so high, and it would end in a short period of time.
Therefore, when route was first planned, two-way, two-lane road was already very spacious, and roads designed at time could basically carry two cars side by side.

And everyone did not take into account that there will be so many cars on road, mostly pedestrian passage is located next to the passage for cars, and not so many roads for vehicles are planned and built.
These kinds of historical reasons related to road planning are more visible in big cities. Why do you say that? Because when we go to big cities, we will find that noisy neighborhoods are mostly built slowly from places where there used to be a lot of people.

In addition, after road was built, people quickly gathered around it, and there was very little space for widening road when people had already built houses and shops next to it, and these roads were planned for a very long time. reserved for road expansion.
Then it will add more difficulty to improving that road at a later stage, and there is no way to expand or optimize it on original basis. In addition, land in city center is very expensive, demolishing houses on both sides of road just for traffic convenience is unrealistic, because such expensive land prices are unaffordable. a company that builds roads is unbearable.

The second reason is that quality and skills of driver are not balanced.
It is impossible to guarantee quality of work of a large number of drivers and manage them. Many people have very poor quality and change lanes at will while driving, and If you don't turn on your turn signal when changing lanes, there will be many road safety hazards .
After a car accident, road will be congested for a long time. This happens not only on highways, but also on city roads.

And on relatively narrow roads, such as rural trails and intercity roads, a car accident causes long traffic jams.
Moreover, I saw news on Internet. This news is all about female drivers or some kind of road killer. They will make mistakes when they are in a hurry. No one can guarantee that they are very experienced in driving.

But these people try not to take heavy traffic roads unless they have experience. There are also many beginners who are very nervous when they first get behind wheel, their arms and legs are very stiff, and they will encounter some unexpected situations in process of driving, and there is no way to deal with them in time.
Even slow down. On a freeway or highway, if you slow down at will, it's easy to create a long congested convoy.

The third reason is that parking growth rate is relatively slow.
The rapid increase in number of vehicles leads to a rapid increase in traffic load, and all these vehicles require parking. We stay longer when we drive to work, so we often have a difficulty finding a parking spot when we leave house, and we even have to travel far.
So when we go to a destination in a remote place, this process wastes a lot of time, and this time, other vehicles cannot park in original parking space, causing other people to waste time forms a vicious circle .

Especially in parking lots around shopping malls and in parking lots of small residents, layout of their parking spaces is far from meeting people's needs, so this situation is also a very important reason for the congestion of vehicles.
