As a representative of foreign smart cities, what are the characteristics of Barcelona’s urban construction?

Barcelona Smart City is a comprehensive plan that covers all aspects of the city, from information infrastructure, smart social public services, to the green and sustainable development of the city. It is an inclusive and open system .

1. Interconnected Barcelona

Now Barcelona’s comprehensive underground network has covered the entire city, with a total length of 375,000 meters of urban network and 100% FTTH coverage covering the entire city. At the same time, citizens can simply and conveniently obtain free Wi-Fi public access points covering the whole city through APPs. 721 Wi-Fi hotspots allow citizens to obtain network services anytime and anywhere, and enjoy the interconnected online world. "Fiber to the Home" is a pilot project to install a fiber optic network indoors in Poblenou to multiply the bandwidth of the area. And "T-City Friedrichshafen" is a city digital network, ultra-fast optical fiber and mobile networks improve data transmission and implement applications; among them, there are more than 300 kilometers of optical fiber and intensive information application technology based on the urban management model.

2. Perceived Barcelona

Barcelona attaches great importance to the role of the Internet of Things in smart cities. The city covers a large area of ??wireless sensors and routers. These devices generate a large amount of data every day. These data flows to the open software platform, where data collection and analysis are further performed to provide guidance for more effective city operations. For example, one of the unique functions of the intelligent garbage recycling system is that it will actively send out a signal when it is full, and the staff will arrange and distribute the travel frequency and route of the garbage transport vehicle based on the signal, thereby improving the efficiency of garbage disposal. The same is true for smart irrigation systems. Ground sensors provide real-time data such as humidity, temperature, wind speed, sunlight, and air pressure. Gardeners can adjust plant irrigation schedules based on basic data and irrigate more scientifically.

3. Open Barcelona

In order to make Barcelona smarter, the city has chosen an open platform, aiming to accelerate the development of future sensors, networks, maps and software analytics to integrate data from the platform. for their use. The platform also allows city departments to share information and avoid duplicating each other’s work. For example, drivers only need to download a special application to obtain information about empty parking spaces based on the information sent by the data platform, which facilitates drivers to park safely and conveniently and prevents wastage of time. Similarly, both citizens and tourists can find the nearest bus station, geographical location, and tourist destinations based on visual map data and interactive browsing.

4. Green Barcelona

Barcelona is committed to promoting low-carbon green environmental development policies. In an effort to reduce CO2 emissions, Barcelona has launched a new green city operation plan covering energy alternatives, transport management and green buildings. As early as 2000, Barcelona was the first to support the use of solar energy by residents throughout the city. By 2006, Barcelona had become the city with the highest density of solar panels in Europe. At the same time, Barcelona is vigorously promoting the use of electric vehicles, deploying charging stations throughout the city, as well as green transportation-related facilities and services such as electric vehicle fleets and car rentals. By 2012, the city had more than 500 hybrid taxis, 294 public electric vehicles, 262 charging stations, 130 electric motorcycles and about 400 private electric vehicles.

5． Serving Barcelona

Barcelona focuses on improving the welfare and quality of life of citizens, in smart lighting, smart grids, smart water services, zero-emission mobility, smart parking, smart transportation, smart district cooling and heating, government affairs disclosure, etc. Remarkable results have been achieved in smart services that promote people's livelihood. For example, in 2012 the city of Barcelona developed a master plan, and the project included the control of 50 street-level street lights, with a total of 1,155 street light masts, to LED lighting technology. Barcelona is on track to reduce its municipal energy bills by a third based on energy-saving LED streetlights alone, according to new research from the University of Pittsburgh that finds they can offer the best green alternatives to cities with life cycle studies analyzing energy-saving LED streetlights alone.

6. Innovative Barcelona

Barcelona advocates technological innovation and has opened up a block of about two square kilometers in the city's high-tech center dedicated to research and practice. Since the textile industry number here used to be 22 in the communication library of the Barcelona Municipal Government, this experimental area was called 22@, which means the combination of tradition and modernity. This old city renovation plan uses a series of smart technology means, including: promotion of free charging facilities for electric vehicles, smart sensor garbage collection points, parking garage and parking space management with smart sensor facilities, and management of residents’ public water use and water conservation programs. It can be seen from these projects that Barcelona focuses on applying innovative scientific and technological means to the construction of urban life infrastructure, so as to achieve the purpose of energy conservation and environmental protection and improve the quality of citizens' life.
