January 28, 2009，Obama, who had just taken office as President of the United States, met with then-President of IBM, Palmisano Palmisano, as a representative of industrial and commercial leaders。Peng Mingsheng formally proposed the concept of “smart planet” to the Obama administration，It is recommended to invest in the construction of a new generation of intelligent information infrastructure。September of the same year，Jointly announced by the City of Dubuque, Iowa and IBM，The first smart city in the United States will be built。

The beautiful scenery of Dubuque，The Mississippi River runs through the city，It is one of the most livable cities in the 188bet app download United States。With the goal of building a smart city，Dubuque plans to leverage IoT technology，Convert all resources of the city (including water、Electricity、Oil、Qi、Transportation、Digitalizing and connecting public services etc.，Monitoring、Analyze and integrate various data，In turn, intelligently respond to citizens’ needs and reduce the city’s energy consumption and costs，Making Dubuque a better place to live and do business。

The City of Dubuque’s first step is to install digitally controlled water and electricity meters in all homes and businesses，Contains low flow sensor technology，Preventing waste caused by water and electricity leakage。

Build a comprehensive monitoring platform at the same time，Promptly analyze data、Integration and display，Make the entire city’s resource usage clear at a glance。What’s more important，The City of Dubuque releases this information to individuals and businesses，Give them a clearer understanding of their energy consumption，Have a greater sense of responsibility for sustainable development。

Spain:Sensor project allows smart city construction to be fully based on practice

According to Mariano, head of the sensor project at the Barcelona Institute of Communications˙Introduction to Lamarca，Smart city is one of Barcelona’s most important projects at the moment，The original old industrial area of ​​Barcelona textile industry，Now it is the most important test site for this project。

“The little black box on the traffic light over there，Can send signals to receivers in the hands of nearby blind people，And cause the receiver to vibrate to remind it that it is approaching an intersection。" Lamarca pointed to the road and introduced。

“Do you see the little bumps on the ground??That’s the parking sensor。Drivers only need to download a special application，You can know where there are empty parking spaces based on the information sent by the sensor。Barcelona’s 188bet sports betting app download iconic Sagrada Familia is where tourists gather，A relatively complete parking sensor system has been established there，Guide buses to park。”

"This is a smart trash can，The sensor on it can detect whether the trash bin is full。According to the information from the sensor，The garbage collection center can develop a database，And arrange the route of the garbage truck。Also，The trash can is also equipped with an odor sensor，If the litter box smell exceeds normal standards，The sensor will sound an alarm to remind you。”

“Our smart city construction projects are not very large in scale，But there are many types，Some of these are experimental，Some have been further promoted and implemented。”As one of the direct participants and main persons in charge of the construction of smart city in Barcelona，Lamarca has his own unique views on smart city construction，“Technology and products are dead，The reality is flexible and changeable，Smart city construction must be fully based on practice。”

Northern Europe:Smart transportation reduces congestion and reduces emissions

Back in 2007，The European Union has proposed and begun to implement a series of smart city construction goals。The EU’s evaluation standards for smart cities include smart economy、Smart environment、Smart Governance、Smart mobility、Six aspects of smart living and smart people。And the Nordic countries are improving transportation，There are lessons worth learning from in promoting energy conservation and emission reduction。

Take Stockholm, the capital of Sweden, as an example，The city has achieved excellent results in combating traffic congestion。Specifically，The city sets up 18 roadside monitors on roads leading to the city center，Using radio frequency identification、Technologies such as laser scanning and automatic photography，Realized automatic identification of all vehicles。

With these devices，The city charges a congestion 188bet app download tax on vehicles entering and leaving the city center between 6:30 and 18:30 Monday to Friday，Thus reducing traffic congestion levels by 25%，Also reduced greenhouse gas emissions by 40%。

Another example is Copenhagen, the capital of Denmark。This city known as the “Bicycle City” has made great achievements in green transportation。To encourage citizens to use rail transit with the least carbon dioxide emissions，The city passed the overall planning，Strive to ensure that citizens can use rail transit within 1 km of their homes。

The traffic on the 1-kilometer road obviously relies on bicycles with a strong mass base。In addition to building three “bicycle highways” and providing repair and other service facilities along the way，They also provide RFID or GPS services for bikes，Ensuring smooth travel through the signaling system。

South Korea:Strongly promote the intelligentization of government administrative services

South Korea is becoming network-based，Create green、Digital、The ecology of seamless mobile connections、Smart City。

2003，The Korean government launches the “U-Korea” development strategy，Hope to build South Korea into a smart society。“U” is the abbreviation of the English word “Ubiquitous”。This development strategy is based on wireless sensors，Digitize all resources in Korea、Network、Visualization、Intelligent，Thus promoting South Korea’s economic development and social change。This national macro strategy is specifically implemented through the construction of "U-City"。

On the basis of building “U-City”，June 2011，Seoul releases “Smart Seoul 2015” plan，Shows the world the city’s ambition to build a smart city。

For example，Proposed by Seoul，Issue certificate、Paying taxes and other administrative services that are now the responsibility of government agencies and websites，Expansion to the use of mobile phones in stages from 2012。By 2014，Citizens can use 188bet app download smartphones、Tablet enables 81 Seoul City administrative services。

Songdo, South Korea is also regarded by many as a template for global smart cities。This new smart city is located on an artificial island about 65 kilometers west of Seoul，An area of ​​6 square kilometers。The project started construction in 2000，A total investment of US$35 billion (approximately RMB 214.2 billion)。

Due to the close connection between Songdo’s information systems，Thus critics also call it "a city in a box"。Give an example，In Songdo，The elevator will only start when someone is riding it。In every household，Telepresence devices are as common as dishwashers。Songdao is expected to be completed in 2015，By then the number of households in the city will be 6.50,000 people，The number of people employed in the city will reach 300,000。

Singapore:“E-Government” serves citizens

The cornerstone of smart city development is complete information and communication infrastructure。Since the launch of the information and communication development blueprint "Smart Country 2015" in June 2006，Singapore has been working hard to build an intelligent country and a global city driven by information and communications，And become one of the countries with the most developed information and communication industry in the world，Improved productivity and efficiency in various public and economic sectors。

As of 2012，The new generation broadband network has achieved 95% coverage，Maximum network speed up to 1G，More than 250,000 users，Home users and business users can subscribe to a variety of fiber optic broadband network access service plans provided by 17 service providers。

More than 7,500 wireless network public hotspots deployed across the island，Equivalent to 10 public hotspots per square kilometer，Access speed up to 1Mbps，The current number of users exceeds 2.1 million。
