The injured Chen Zier couldn't do anything, so he devoted all his time to his academics, and with his personal experience of the city in later generations, he probably found the answer to the previous question.

The question he was thinking about before was, why have our cities in China built so many roads, so many subways, and our infrastructure is so high, but there are almost no cities that are not blocked!

The number of people is an important factor, but it is precisely because of the large number of people that every kilometer of road is used very efficiently.

Chen Zier carefully sorted out her views and prepared to write them in the paper, which helped Sheng Qianyu a lot in this process, and also made Chen Zier find that she was really kind.

Because few people can take other people's affairs as their own, Sheng Qianyu really tried his best to help him, whether it was the explanation and application of some complex formulas in the book, or the adjustment of the format of his final paper.

This really helped Chen Zier, he never thought that the format of the paper would be so important in academics.

There are not many rigorous formulas in his paper, but he makes two very clear points.

First, the construction of urban roads should be people-oriented, not car-oriented. How to understand this?

Chen Zier didn't know how other people felt, anyway, as far as he was concerned, he didn't like the wide road in the city. Especially later, many cities engaged in XC district planning. What kind of plan is that?

Road, one-way, at least four lanes!

The state stipulates that each lane is 3.5m wide, and the two-way eight lanes plus green belts and non-motorized lanes make that road almost 35m wide!

Yes, the road is very beautiful, and the car feels comfortable driving on it, but do you want to cross the road with pedestrians? 35 meters!

Have you ever thought about the residents who live on both sides of the road? That is, the community has been basically separated from the community, from the people! The so-called steel forest, the steel forest, isn't that it, and there is no human touch in the whole urban area! This is obviously a city built for cars, where is it built for people.

Moreover, if people go out and have something to do, they may have a distance of several kilometers after crossing two streets, and those who have cars will drive on ironclad, and the roads are wide and easy to drive. What is this vicious circle! Don't talk about building eight-lane two-way lanes, you can build sixteen lanes in two years to see if they are blocked.

Therefore, urban transportation should be people-oriented and convenient.

Second, in the process of urban road planning, it is necessary to start from the perspective of people, not from the perspective of birds. What does this mean?

In fact, this is the experience that everyone has: in later generations, even if it is a small county town, from the air, even if the aerial photography is not beautified, the city looks spectacular, but if you go down and take a look, three words: dirty and messy.

Even if it is a first-tier city, you look at it from the air, is it not beautiful? Needless to say, it can basically be compared with the CBD of any city in the world, but if you go down and take a walk, it feels the same as looking at it from the air?

Therefore, many roads and urban functional areas are drawn by planners with a pen and a top-down perspective, which can be said to be very beautiful. But what's the use? For people who live in the city, I can't look down, you can't let me watch aerial documentaries every day, right?

In the office, Professor Wang took Chen Zier's paper and looked at it, at first when he was browsing, he saw that the whole article was full of words, and he thought that what kind of good paper could it be?

Chen Zier added next to him: "Our country has a large population and great demand, and the roads must be repaired more, but I don't think blindly building expressways can solve the problem." ”

"If we continue as we do now, then in the end, the bridges in our city will be cosmic-level, the expressways will be world-class, the main roads will be European-American, the secondary roads will be African-level, and the branch roads will basically be Indian-level. ”

Professor Wang was amused and pretended to criticize, "Why are you still engaged in state discrimination?" ”

Chen Zier said with a smile: "Then India's infrastructure is poor." It's a joke to say, but for urban traffic it is a disaster, Professor Wang, you also said that urban transportation is a big system, so I can understand it this way, the main road of the expressway is like the main artery of the human body, I don't mean not to build the main artery, but the capillaries are also very important. The path is not good, everyone finally crowds into the expressway, and it is also blocked!"

Professor Wang's face was solemn, he was an old professor and naturally knew such consequences.

Chen Zier is clear that the big cities of later generations are Indian-level paths, and as a result, everyone squeezes the expressway, and in the end, the expressway will be on the traffic light.

Expressway, expressway, as the name suggests, is to be fast, for this reason is basically not to set up traffic lights, but later there is too much traffic, do not set up, especially in the intersection of different directions of traffic.

So obviously, what happens if the trail is bad?

Even if a private car goes out, he may have to go on the elevated highway at a distance of two kilometers! Millions of cars in a city are belched, and everyone is squeezing on it, and they are fast with a hammer!

Professor Wang said: "Your idea is very insightful, and the paper is well written, but after all, we are science and engineering disciplines, and it is not a matter that the whole article is full of words, so let's polish your paper together, add some theoretical research, and it is best to use the model to deduce the results, so that we can definitely produce a paper of excellent quality." ”

Chen Zier made a difficulty: "Teacher, I am not good at high mathematics. The theory is also choking enough. ”

"I can help you get this slowly, your idea is good. In addition, you can rest assured, I am sixty years old, and I will not ask for this first author, the first author will definitely write your name. ”

Chen Zier waved his hand again and again and said: "I am a student, you are a professor, you must be the first author, otherwise it is not suitable!"

He didn't want to be famous, as long as the idea could be taken seriously. Professor Wang is not kind either, how old is he, he has already seen through this.

However, these can be pressed first, and the paper will be published first.

Seeing that there was such an idea of a student in the class, Professor Wang had a big heart in his heart.

Chen Zier also felt refreshed when he walked out of the office, and in a sentence full of positive energy: people will also get happiness in the process of helping others.

It's not how noble the sentiment is, it's just that in this process, the individual's sense of existence will become very strong at this moment, and Chen Zier feels like this now.

He felt like he had done something that would benefit thousands of people!

~~~~~~~~

Chen Zier hummed a song all the way, and almost jumped. When he walked downstairs to the dormitory, he was stopped by Song Xiaobo.

Chen Zier asked, "What are you doing here?"

Song Xiaobo's face was embarrassed, and he pulled Chen Zier to a slightly more remote corner.

Chen Zier saw that he couldn't say anything and thought something was wrong, so he urged: "If you have anything, just say it, they are all roommates." ”

Song Xiaobo gritted his teeth and said, "Third child, I want to ask you to borrow some money." ”

Damn, are you embarrassed about this, it's not normal for roommates to lend each other something.

Chen Zier asked, "Okay, how much to borrow?"

Song Xiaobo said: "8000. ”

I was taken aback, and asked worriedly: "Are you in trouble?

"No, it's Zhang Jin, she has been making trouble for a long time and has always wanted a Nokia mobile phone, I have never bought her anything good, she wants this mobile phone so much, I want to buy it for her. ”

Chen Zier smacked his mouth, he didn't say anything, it wasn't an accident, he said: "Okay, it's no problem, but I don't have that much cash now, you come with me to the bank." ”

Song Xiaobo is a very honest person, Chen Zier's readily agreed to make him a little embarrassed, and he whispered: "Thank you." ”

Chen Zier patted him on the shoulder, "It's the nature of every qualified boyfriend to love his girlfriend, and I can't let worldly money get in the way of this." I'll lend you the money, you don't have to rush to pay it back, and you don't have any burden, we are roommates. ”

He has always been a generous person, and although he spends some extra money, these expenses will always bring him something else, even something that cannot be measured by money.

It's just one thing, he doesn't know whether he should say it or not, at this time, it is understandable that many people, especially young people, are crazy in love with Nokia, but they still pester Song Xiaobo to buy it for her when they don't have enough financial ability.

It's not a good girlfriend's choice.

Of course, in the end, he shut up. People are two people, and they will nag about anything. When the time comes, Chen Zier has said such things, he is just looking for trouble. Besides, there may be any other reason for this, 8,000 yuan, borrow it, borrow it, and get into a bunch of trouble after borrowing, it will be more than worth the loss.

Outside the bank, Song Xiaobo held 8,000 yuan in his hand and said fiercely: "I must make money in the future!"

Chen Zier cheered for him, which was actually the state he was in when he was in college in his previous life.

The most hurtful thing about men in modern society is that you have almost nothing at the age when you value feelings the most. By the time you have the ability to paint the future, the people around you will be long gone.

At the end of November, Chen Zier's forearm was basically restored, and the house in Dijing Lanwan was gradually coming to an end after three months of renovation, and he gradually ran more often.

At the beginning, Chen Zier didn't feel it at all, but the closer he got to completion, the more itchy his heart became. In the past, he thought that three months would not matter if he could wait, but now a few days he feels that it is extremely long.

It's really hard to explain this human mentality.

All in all, his days in the school's dormitory, that was not long.
