Professor Wang's full name is Wang Fukang, who is the 'main force' professor of the School of Transportation and Transportation, who was originally engaged in systems engineering, but for some reason later transferred to the transportation industry, but the transfer is not too far, because whether it is a city, a region or even the whole country, transportation is a systematic project. Roads, railways, and airlines are not completely independent of each other.

He gave a lecture on urban transportation to the sophomore year, and Chen Zier listened to it twice and felt that it was average, mainly because the old professor's academic level was too high, and he thought that it was very simple things, and the students were very confused when they heard it, and this phenomenon exists in the university. But the old professor is very anxious, and he is still a little hot, and he usually gives heavy tasks, and if he can't complete it, he will be criticized, which makes people panic.

Therefore, in order not to block the hard-working old professor and not to block himself, Chen Zier went back to class in a hurry, and the report he handed in last time was a little confused, and he couldn't skip class again.

When he arrived at the classroom, Professor Wang was already there, but it should have started not long ago, Chen Zier entered the classroom and sat next to Cai Yifeng in the back.

"It's a lifesaver, a little less of a meal. Cai Yifeng stared at the blackboard with his eyes, pretending to listen carefully to the class, and whispered.

Chen Zier put up an 'ok' gesture, "It's a small thing, it's easy to say." ”

"Bright. ”

Professor Wang is almost 60 years old, but the lecture is very loud, he must have been used to lecturing for many years, and his attitude is very serious, and everyone does not dare to talk more.

It wasn't until the end of class that Cai Yifeng said to Chen Zier: "The last time I told you about the student union, it's okay, the minister of literature and art nodded." ”

"So easy?" said Chen Ziyi.

"Hey, there aren't many people who can do this expensive thing like the piano these days, I directly told my senior sister that you are a piano grade eight, and she was so happy that she almost used eight sedan chairs to carry you. ”

Chen Zier was speechless, "Eighth level? Why don't you blow the tenth level! I've only been studying for a year, and the fifth level is enough! You the eighth level, what if you can't complete the task when the time comes?"

Cai Yifeng's heart did not fluctuate, and said: "I don't believe it if I blow the tenth-level senior sister, it is still the eighth-level reliable." ”

Chen Zier: ......

Cai Yifeng said again: "What are you panicking about, there is really a show that you can't handle, you pull Zhou Zijun here, she is so strong, any difficulties will become invisible in front of her." ”

Chen Zier didn't know what to say. I just hope that the minister knows the truth and remains calm.

"There's one thing you're out of luck, though. Cai Yifeng shook the ballpoint pen and said with an old Shen look.

Chen Zier thought there was something bad, and asked seriously: "What's wrong?"

"In the student union, there are also beautiful girls, but there are really few who are more beautiful than Zhou Zijun, in fact, our minister is very good, but I just heard that she talked about her boyfriend two days ago. Dude was supposed to introduce you to a few girls.,Think about it so carefully, I find that I don't have the resources for it.。 ”

Chen Zier's face was black, "Listen to the class with peace of mind!"

Cai Yifeng sighed: "Alas, your single problem is a bit difficult to solve." ”

Chen Zier: "That meal is gone." ”

Cai Yifeng closed his mouth when he heard this, but he was not in a hurry, Chen Zier's character was not a person who was stingy with a meal, so he didn't worry at all, but he was smiling at the thief over there, and he was very cheap!

In fact, Cai Yifeng said that the beautiful minister Chen Zier has not seen it, if he liked it, he would have chased it a long time ago, that is, he was in a better figure, the key is that his skin is a little dark. As the saying goes, one white covers a hundred ugliness, and one black destroys everything, at least Chen Zier thinks it makes some sense.

In the second session, Professor Wang returned to class.

The traffic in the city is different from the big traffic such as highways and railways, and it includes some more detailed things, such as the planning of the city's main roads, the layout of the bus network, and a little more detailed, whether the city's main roads are built with two-way six lanes or four lanes, and how many seconds are set at the traffic lights at intersections. Anyway, there's a lot of minutiae in it.

But until the first decade of the 21st century, including the entire nineties, the general idea of transportation throughout the country has been skewed.

Specifically, Professor Wang agrees with the idea that the city should build more main roads, the roads should be wide and beautiful, and the officials will also like to build an overpass and engage in some image projects.

This is basically wrong, Chen Zier felt that there was a problem when he heard it, 20 years later, is the road in Yanjing wide? Are there many overpasses? Is the road in Zhonghai wide?

But it's blocked? The blockage kills people.

The bus has also been done, and the Zhonghai Metro has repaired 189 lines, has it solved the problem?

Those who nod their heads will know when they drive to work during the morning rush hour.

Chen Zier did not study transportation in his previous life, and he didn't know where the problem was, the only thing he was sure of was that no matter how wide the road was built in the city, no matter how many elevated roads were built, this was the result of the final practice, and it could not be denied.

Despite this, Chen Zier certainly wouldn't be stunned to have a big debate with Professor Wang in class, and he finished this class honestly.

But he always felt in his heart that he needed to do something, what was the purpose of being reborn? Isn't it just to correct the mistakes of the past?

Perhaps he alone will not be able to solve the problem of congestion in large cities in China in the future, because the population is large.

But on the flip side, it is precisely because of the large population that it is even more important to avoid making mistakes to save the already precious urban road space.

Chen Zier pondered by himself what the problem of this idea was, and after having a little idea, he still found Wang Fukang.

Professor Wang looked stern, but he welcomed the students to discuss problems with him.

Chen Zier didn't come with him, and after a simple greeting, he said to him directly: "Teacher Wang, listening to your lectures in the past few weeks, I always feel that blindly building excessively wide roads and elevated highways in the city may eventually be blocked. ”

Professor Wang asked, "What do you think?"

Chen Zier said: "I don't have any special ideas, I just think that the speed of road construction can never catch up with the growth rate of cars, you also said in class, the road is repaired, it will also induce an increase in traffic flow to a certain extent, so I am thinking that the final result may be: the road is more and more congested!"

Wang Fukang felt a little interesting when he heard it, but he still insisted on his own proposition: "Our country is now developing rapidly in the economy, and the burden left over from history is too heavy, although the infrastructure of the city has been carried out for several years, it is still not enough, at least from the current point of view, the total supply is still not enough, how can you let more and more cars in the city go without building roads?"

This is also a problem, Chen Zier scratched his head, he thought for a while and said: "Of course, road construction still has to be repaired, I mean there is no need to blindly pursue increasing the supply of roads to meet the travel needs of urban residents, because no matter how much it is repaired, it will definitely not be satisfied, and more and more people will buy cars in the future, there is no problem at all with 3 or 4 million motor vehicles in a city as big as Zhonghai, how many roads can be repaired to meet?"

Wang Fukang smiled, "3 or 4 million vehicles? Zhonghai only has hundreds of thousands of cars now, how many times does it have to be enough?"

Chen Zier was anxious, the congestion problem in big cities, in addition to the challenge of a large population, no one estimated that the country's economic level was improving so fast, and the vehicles entered people's homes so quickly, which is also an important reason.

In fact, compared with other first-tier cities, Zhonghai is not gambling, because since 92 Zhonghai began to implement the photo auction policy to control the growth of motor vehicles, without this foresight, it is estimated that it is not much better.

But how do you convince Professor Wang that the number of vehicles will rise so fast in the future?

Chen Zier couldn't do anything for a while, he only blamed himself for his lack of academic excellence, and he wanted to convince a professor of half-baked skills.

He decided to go back and study the problem carefully, check the data, look for theories, and finally form a reasonable and well-founded text, so that the professor would still recognize him.

It is obvious that these materials should be found in foreign books and periodicals, and that if foreign cities are well built, the relevant theoretical development will definitely be more perfect.

For others, this is a difficult thing because they can't understand it.

But for Chen Zier, this is not a problem.

To make the world a better place, start with a few small details, and if you're lucky, you can use this for your graduation thesis.
