　　"It's a red light now, please don't run through a red light!" When it is not the traffic police who said this to you, but the traffic lights at the intersection, do you think you have entered the world of science fiction in the movie?

　　In fact, this is an intelligent transportation system in real life.

　　Recently, the interview team of the "2020 Fingertip Cities" network theme event walked into the "brains" of many cities and found that with the development of technology, intelligent transportation systems are only the tip of smart cities, and more have appeared in science fiction movies. Fantastic ideas have entered the real life of citizens.

You can walk at traffic lights and eat with your face...

　　The traffic lights may not only "talk" but also "walk".

Should have stood at the traffic lights on the cross street, now they learn to "ride" the bus by themselves.

　　On October 24, Changsha, Hunan, a 315 smart bus departed from the starting point.

This batch of smart buses will synchronously transmit the real-time traffic light information of the intersection to the LED screen at the rear of the vehicle to help the rear vehicles avoid the embarrassment of following the car accidentally running the red light due to blocked vision.

　　In addition, smart buses can count traffic information based on big map data, and adjust the timing of traffic lights through the bus priority function to achieve accurate arrivals. Passengers don't have to worry about buses arriving late or leaving early.

The electronic screen in the car can also display the current number of passengers, arrival and transfer information in real time.

　　Smart public transport has only managed to "come to and from get off work" on time. In some cities, government affairs halls have already opened the non-closing mode. How hard are the staff?

No.

　　In Chongqing Liangjiang New District, more than 30 smart devices in the 24-hour self-service hall can not only inquire about social security, provident funds, print birth certificates, death certificates, etc., but also handle various living expenses, and perform 993 matters in 19 government departments. guide.

　　If you need to submit the corresponding physical materials, you can also directly swipe your ID card and deposit it in the filing cabinet for free. After the staff receives the corresponding information, they can hand over the materials without contact, truly being on duty for 24 hours and serving "only for you".

　　However, there are always small partners who are not worried, all kinds of documents and proofs are dazzled, and one "run in vain" if you bring one less.

In Wuhu, Anhui, the government "moved" the civil service hall to you.

　　Zan Zhiwei, secretary of the party committee of Wuhu Huaqiang Community, introduced to Chinanews.com that the community uses the Wuhu city's grass-roots integrated service platform to enable residents to fill out the application items online. What materials are needed at a glance, the office staff can view and accept applications in real time, and do not run back and forth.

　　With the advent of the digital age, the application scenarios of face recognition have already penetrated into daily life.

You can eat, check credit, receive pensions, travel, study, and see a doctor without even having to use your hands.

　　On October 23, the smart system of "e Yang Canteen" in Dongtou District, Wenzhou City, Zhejiang Province was officially launched. Elderly people who need home care and meals, themselves or their children log in to "Dongtou Canteen" through WeChat public account, and add information about the elderly dining. , You can book the meal service for the elderly the following month without leaving your home.

After ordering meals online, the elderly can eat directly in the canteen for the elderly just by brushing their faces.

　　"These are obvious changes that ordinary people can directly feel. In some places they can't see, in fact, smart cities are also working hard." Wang Yifei, head of the Alipay Smart City One Netcom Office project team, introduced to Chinanews.com.

The "urban brain" really "thinks"

　　Wang Yifei said that if you find green lights all the way one day, don’t be surprised that your luck is too good. This is the "urban brain" through calculation and analysis. According to the current traffic speed and density, how much traffic efficiency can be improved by the green light all the way? Dispatch instructions.

　　"The previous traffic lights were set in advance. Even if there is no car at the intersection, there will still be a 30-second red light, but now it can be adjusted in real time according to the algorithm. People may just think that traffic is not too congested, but they don’t know that behind this is a smart city. I don’t know who is doing it.” Wang Yifei said.

　　There is such a "urban brain" in Hangzhou, Zhejiang Province.

At the "2020 Fingertip Cities" web theme event, Fu Weiquan, a member of the Party Group of the Hangzhou Data Resources Administration, said that the original intention of the city brain was to achieve digital control of congestion.

Nowadays, Shangcheng District of Hangzhou is also the first to promote the empowerment of the urban brain to the grassroots level and carry out the practice of "urban brain block governance".

　　For example, Hangzhou Hubin Smart Pedestrian Street is crowded with 50 million people last year.

By accurately monitoring the flow of people in each block, realizing real-time checking of the number of people online, and optimizing the three-level response plan, the lakeside block has realized an efficient and orderly safe flow of people management.

　　In addition, a total of 2413 berths in the 9 independent parking lots around the pedestrian street are unified as the pedestrian street supporting facilities, connected to the "urban brain" for real-time online calibration.

Set up smart guide signs in obvious locations around, so that car owners can learn about key information such as vacant parking spaces and driving routes on the way, and find parking spaces nearby.

　　"Urban governance is changing from passive to active." Zhao Mingjun, chief architect of Tencent Cloud Smart City and deputy general manager of Tencent Cloud's government affairs industry, told Chinanews.com that in many important streets, some public areas can be judged by cameras in the area. Phenomena such as vehicles giving way to pedestrians.

"Many things that used to be manual are now solved by automated means. The application of intelligent technology has brought about big changes."

Who makes the city more and more "smart"?

　　Behind the increasingly smarter "urban brain" is the support of big data, artificial intelligence, cloud computing and other related technologies.

Wang Yifei said that the construction of smart cities can be divided into three layers. The first layer is the lowest-level technology, including cloud computing, blockchain, artificial intelligence (AI), and so on.

Above the technology is the data layer, mainly from government data.

Above the data is the application layer, which is directly accessible to the government and citizens.

　　In Zhao Mingjun's view, the technical level is relatively mature.

Nowadays, the application of smart city is not only embodied in the mobile terminal of mobile phones, but also the extension of community self-service terminals, TV terminals, and physical halls, PC terminals and other "terminals" can provide interactive services.

"There is basically no big problem in data aggregation, modeling, organization and storage, and visualization."

　　In addition to policy encouragement and support, the achievements of smart cities today are not unrelated to the efforts of many companies.

　　In 2014, the "Guiding Opinions on Promoting the Healthy Development of Smart Cities" jointly issued by the National Development and Reform Commission and other eight departments established the basic principles of smart city construction: people-oriented, pragmatic advancement; adapted to local conditions, scientific and orderly; market-oriented, collaborative innovation; manageable Controllable to ensure safety.

"Encourage social capital to participate in construction, investment and operation, and prevent the government from overwhelming and unnecessary administrative intervention."

　　Data from the professional version of Tianyancha shows that in recent years, my country's smart city-related enterprises (all enterprise status) have increased year by year.

In 2019, the number of related companies was the largest, reaching more than 3,200, with an annual growth rate of 38.76%.

In 2020, my country has established more than 2,600 smart city related enterprises.

　　At present, the country's only business scope includes "smart cities", and there are more than 13,000 enterprises whose status is active, existing, moving in, or moving out.

In terms of industry, 43.64% of enterprises are in information transmission, software and information technology services, and 21.64% are in scientific research and technical services.

Are China's smart cities already "little geniuses"?

　　"I personally think that smart cities are still in a relatively early stage." Zhao Mingjun said, because the original smart cities are some applications in the vertical field, which are relatively scattered.

‍‍In the past two years, it has begun to emphasize data integration and public support at the city level.

The difficulty lies in the collaboration of data, and the promotion of specific application scenarios also needs to gradually establish habits.

　　Liu Zhiyan, director of the Urban Information Integration and Dynamic Simulation Laboratory of the Chinese Academy of Social Sciences, told Chinanews.com that the development of smart cities should be evaluated from the application areas, including smart industries supported by network information technology, smart people’s livelihoods, and smart management. aspect.

　　"This involves new energy, new materials, cultural creativity, modern agriculture, aerospace, etc. in the industry; e-commerce, pension, medical care, travel and other aspects of people's livelihood." Liu Zhiyan said, if any place in the world is said to be completed It is impossible to build a smart city. Due to the uneven development levels of various regions in my country, the construction of smart cities is more difficult, but the degree of local emphasis is crucial.

　　Liu Zhiyan believes that in the construction of smart cities, the government and enterprises should be a way of cooperation.

What the government solves is left to the government, and the other part can be handed over to the market.

　　“For example, smart services such as a community’s property and water supply can be handed over to the company. Another example is the construction of smart city buses. While the company provides service information such as waiting time and the number of vacant seats, it can also allow them to advertise at the station. Through franchising The transfer of rights, using market methods to bring smart city construction to a new level." Liu Zhiyan said.

　　He thought of everything you thought of; he thought of everything you didn't think of in advance.

Do you love such a smart city?
