They were looking forward to this, and said that His Majesty must have thought of a way, and urged the ministers to come to the palace to inquire. ”

The people all have high hopes for Li Xingchen, if it is not handled well, it will affect Li Xingchen's reputation, then he will definitely sprinkle his anger on Lin Datian, and if he is not careful, his official road will come to an end.

Lin Datian was sincerely frightened, very anxious, and desperately hoped that Li Xingchen could think of a way soon, and their highway bureau would implement it thoroughly.

"Don't you have a good idea?" Li Xingchen circled three provinces and six departments.

No one has come up with a solution that is better than the traffic lights of later generations.

However, traffic lights do not happen overnight, they evolve gradually over a long period of time.

Unfortunately, the current time is tight, and there is no electricity, so there is no way to learn the follow-up mode.

"Ministers are ignorant, please forgive your sins." The prime minister bowed his head and said, "Otherwise, Your Majesty will issue an edict and let ten thousand people come up with advice?" ”

There are many people and great power, the three stinkers are Zhuge Liang, and the people gather together for various discussions, and they can always think of a way.

"A little thing that needs to mobilize all the people? What do you all eat? Li Xingchen was furious.

The things that need to use the heads of the people in the world are all major matters, and they are also things that the imperial court can never solve!

To a certain extent, this will affect the majesty of the imperial court, and will make the people feel that the imperial court is very wasteful, so no matter how difficult the problem is, the imperial court will have to carry it by itself.

"And what does Your Majesty think?" The prime minister asked stiffly.

"I think you can use the form of color to decide whether to stop or move forward, such as green light and red light." Li Xingchen said the idea of the traffic light in the future.

"Huh? Lamps as a rule? ”

The prime minister and others are a little confused, very novel, very interesting, but how much does it cost to use lights as auxiliary tools for intersections? What a waste of resources!

To map the red and green colors inside, you need pigments, and the cost will increase greatly!

"Your Majesty, it's too extravagant." The prime minister said.

Li Xingchen knew what they were thinking, smiled, and explained, "This lamp is not the other lamp, not for you to light the lamp, but to replace it with red cloth and green cloth." ”

"You can cut the cloth into a circle and change the color after a while."

These people are so stupid, how can they use lanterns, and how much useless cost does it cost?

In this era, there was no electricity, and it was impossible to imitate the traffic lights of later generations, but the corresponding colors could be used.

"How long does it take to change color? At the crossroads, there were people on all sides, horse-drawn carriages, bicycles. It's not just going straight ahead, it's all kinds of turns. Lin Datian asked.

This matter is a matter of the Highway Bureau, and no one is more concerned than him, so he must ask everything clearly, otherwise he will not be able to do it, and there will be various problems, and then Li Xingchen will take him again.

"How long it will take needs to be investigated. The initial setting is 60 breaths at a green light and 30 breaths at a red light.

The turning lights in the southeast, northwest and the straights flow separately, so that the traffic lights can not fight. Li Xingchen said in a deep voice.

Lin Datian nodded.

After a while, Li Xingchen said again: "I'm afraid sixty breaths at the intersection is not enough, and I have to take into account the fact that the elderly are not fast."

A pedestrian waiting area can be set up in the middle to avoid the old man and the old lady turning red halfway through, neither entering nor retreating. ”

"Yes, Your Majesty. What if the bicycle carriage has a temporary U-turn? The Prime Minister asked.

"Now the road is divided into left and right, and at the intersection, you can divide the steering and rely on the guidance of the traffic lights.

As for turning right on the right side of the road, you can turn directly without referring to the traffic lights.

If you turn right on the left side of the road, you have to refer to the traffic lights.

In short, everything should be based on the intersection can not collide. ”

The prime minister and others suddenly realized that a car turning right on the right lane can turn to another road without passing through the crossroads, and cars in the left lane must pass through the crossroads if they want to turn right, so they must obey the rules of the traffic lights.

"Your Majesty, the minister still has a question, how did the traffic light change? You can't let people guard there, can you? The prime minister asked again.

With so many intersections across the country, the labor cost is much more expensive than the cost of lanterns.

This is the answer that everyone wants to know.

Since traffic lights are used at intersections, places that are not intersections must also be used, and uniformity is good-looking. Otherwise, there are some places and some places not, which will affect the appearance of the Great Wei State too much.

Li Xingchen smiled, "Didn't you forget the Luban technique?" I've mentioned it to the Ministry of Industry before, right? Collect all the tricks that Luban lost in the people. Ministry of Works, I haven't forgotten this matter. ”

The Ministry of Industry Shangshu nodded excitedly, "Your Majesty, how dare the minister forget what you personally ordered."

A few days ago, Chen has been studying various problems of bicycles with students in the technical college, and at the same time, he has also used Luban technique.

The trivial matter of the change of traffic lights will be handed over to the minister. The minister will study and understand as soon as possible. ”

The Ministry of Industry was in a hurry to make meritorious service, so he smiled happily.

Li Xingchen nodded, and couldn't help admiring himself, so simply using the traffic lights of later generations.

The ministers said in unison, "Your Majesty is wise." ”

I have to say that Li Xingchen's idea is very innovative and very practical, hundreds of times better than the method that these ministers came up with together, so the ministers admired Li Xingchen more and more.

At this moment, the Grand Duke ran into the imperial study, "Your Majesty, General Leng sent someone to send a secret letter eight hundred miles in an urgent manner. ”

As he spoke, he respectfully handed over a letter.

Li Xingchen took it, opened it, and couldn't help frowning.

The letter contains a detailed account of the preliminary investigation of the bandits.

Who is the mysterious masked man? Will it be a family in the Jiangnan area?

If so, what is the purpose of deliberately spending a lot of money to organize ordinary people in Jinyuan County to become bandits?

If not, who did it?

Li Xingchen pinched his eyebrows.

The prime minister looked at him with a bad face and asked, "Your Majesty, is something wrong?" ”

Before the results of the investigation came out, Li Xingchen didn't want to reveal this matter to too many people, so he waved his hand and said, "It's okay, all retreat, let's do their jobs."

Implement the traffic light as soon as possible, and don't delay it again and again. ”

"Yes, Your Majesty goes."

After the ministers retreated, Li Xingchen immediately handed a letter to the Grand Duke, instructing him to send it to Jinyuan County as soon as possible.

At the same time, Leng Tongxiang was on his side.

Ten days ago, Leng Tongxiang led the women's army to Haohan Village and caught another group of bandits.

Their rhetoric is the same as the previous group, they are all approached by a masked man.

It's just that the bastards in Haohan Village have been waiting for news and haven't done anything bad.

After investigation, it was proved that they did not do the evil thing of killing people and setting fires, and Leng Tongxiang let them go.
