While they drank their tea.
Li stood up in shock.
He walked to the edge.
Then he said: "Come here!"
He motioned for the two of them to walk over.
So, the two stood up in confusion and walked carefully to Li Min's side.
It turned out that there was a sand table in front of Li Min.
They seemed to have seen this sandbox when they came in.
But I didn't particularly care.
When the two looked at the sand table carefully, they discovered that it was a miniature of the area around the library.
They were fascinated by what they saw.
Because this miniature is just like the real thing.
It makes people feel shocked.
Duan Lun first asked: "Sir, what is this?"
He didn't understand why Li Min wanted them to see this.
And Li Min said:
"It's the solution."
These five simple words made the two of them very happy.
However, I can't see the solution.
It seems a little unreasonable to be able to see the solution just by looking at the model.
The two of them only knew that the road here was a little different from the library.
Because it seemed to them that there were more lights here.
Some weird lights.
There are two kinds of lights, red and green.
This made the two of them even more puzzled.
Until Li Min continued to introduce:
"Maybe you will be confused, but it is normal for you to be confused, because what I am going to do next is a major event that will change the transportation of the entire Datang. It will also be done after the number of cars increases."
Although I don’t know what Li Min is talking about.
But the two still listened very carefully.
Li Min knew that the two of them didn't understand the meaning.
Then he went somewhere and there was a red button.
I saw him press it.
The car on the sand table actually started to move.
It's almost like it's true.
Duan Lun and Dai Zhou were stunned.
The combination of lighting and car is simply wonderful.
There are not only cars, but also some little people who are shaped into fist-high figures.
These people also started to move.
It's wonderful, simply wonderful.
If Li Shimin was here at this time, he might be extremely shocked.
However, based on these things, it seemed that it was just a small matter. Before Li Min explained how to solve the problem, they still didn't understand the mystery.
Just as the two of them were dazzled.
Li Min asked: "How is it? What do you think?"
The two said they didn't see anything. They just saw cars passing by and didn't feel anything special.
Dai Zhou said: "I didn't see anything, sir, let me know!"
"Yes, sir, what do you do with this?" Duan Lun asked.
"I'm just telling you, you definitely won't understand, so I have this sandbox to let you feel what's going on at the scene."
The two still didn't quite understand.
Li Min added: "This thing I made is called a traffic light, or it can also be called a traffic light!"
"traffic light?"
The two were shocked, what was that?
"Yes, did you see the intersection in front of the library? There are four sets of traffic lights there!"
Following Li Min's finger, there were really four sets of lights, one red and one green.
Why do we talk about four groups? Because there are lights on the top of the pole, and there are also lights below the pole. They are all red and green light bulbs.
"Saw it!"
Dai Zhou said.
"Okay, you see the light on the pole is called a motor vehicle signal light, and the one under the pole is called a crosswalk signal light. You can understand it this way, one signal light is for cars, and the other is for people. They are On the contrary, when the car is moving, people have to stop, and when people are walking, the car cannot move. And I also drew some lines for people, called sidewalks, where people can only walk."
Li Min introduced.
The two of them still seemed to understand each other.
"You see there is no interaction between the traffic and people. I will tell you a few points and you will understand."
Li Min said very patiently.
Then he said:
The rules for motor vehicle traffic lights are as follows: When the green light is on, vehicles are allowed to pass, but turning vehicles must not impede the passage of through vehicles and pedestrians that are allowed to pass.
When the red light is on, no vehicles are allowed to pass.
And crosswalk signal lights
The rules are as follows:
When the light turns green, pedestrians are allowed to pass through the crosswalk.
When the red light is on, pedestrians are prohibited from entering the crosswalk, but those who have already entered the crosswalk can continue to pass or wait at the center line of the road.
…
"So, once this signal light is used in traffic, it will play an extremely important and decisive role in the smooth flow of traffic in the future. It will avoid congestion and increase the pass rate in advance!"
Li Min said so.
But the two of them still didn't understand.
“The method is good, but it’s a bit difficult to understand!”
Duan Lun said.
"Just remember these six words: Stop on red light! Go on green light!" Li Min said.
It dawned on them.
Dai Zhou added: "This is a good idea, but what if someone doesn't comply? This signal light is equivalent to nothing!"
Duan Lun also realized this.
He said: "Yes, this still depends on self-consciousness. If people are not self-conscious, then everything will be in vain, which means there is no change."
Li Min has already had ideas about these things.
He said: "This thing cannot be done by the Shengtang Group alone. The imperial court must come out to host it! Otherwise, everything will be in vain!"
When the two of them heard it, they realized that was the case.
I bet Li Min was waiting for the two of them to come and ask questions.
If that's the case, that would be really interesting.
If that's the case, then people will know why Li Min made preparations in advance.
Now that the method is available, it depends on what the court does.
But what should the court do?
The two of them still have no bottom.
Duan Lun then asked: "What do you want our court to do?"
"If you are the enforcers of the rules! Do you understand what I say?"
The enforcer of the rules?
Li Min knew that the two of them didn't understand the meaning.
Then he added: "I will provide you with the rules, but it is up to you to enforce them. If you encounter someone who does not follow the rules, you can fine them. The purpose of these fines is to deter some people so that they do not dare to violate it again. My suggestion is to The fine for motor vehicles is two hundred cents per time! And the fine for pedestrians is one cent per time. Those who commit multiple offenses can be publicized, because the fine has no effect on them.
As for the role of fines, the first is to educate people, and the second is to generate revenue for the court! It also allows traffic to flow smoothly. This kills three birds with one stone and is a real benefit. "
When Li Min said this, both of them were so surprised that their jaws almost dropped.
It turns out it can still be like this.
Then, next, they have to go to Li Shimin and explain everything Li Min said.
The two of them also stared at the sand table.
Then next, they may want this sand table for other purposes.
