The development of smart cities is a global trend, and gradually evolved into a field of application of international innovation technologies. For example, the annual smart city fairs held in Taipei and Barcelona attract technology companies and government officials from all over the world to participate in the development and become business opportunities. The city’s platform for sharing needs and practices is to launch international exchanges on the theme of smart cities.
Looking at the technological applications of innovative smart cities in various countries in recent years, it shows that applications for the Internet of Things, artificial intelligence, big data, virtual/amplified reality, and financial technology are increasing, becoming the highlights of the annual smart city exhibition.
Taking the Internet of Things as an example, the car networking information platform and services start-up company Tantalum, in view of the fact that London, England, has caused nearly 6,000 deaths each year from nitrogen oxide emissions and affects many children’s respiratory health, with government funding and Imperial College London. Jointly developed a vehicle emission calculation system called AIR.CAR. Through the installation of air quality sensors on 1,000 vehicles, the local supervisory authorities can dynamically adjust road tolls based on the instantaneous information on nitrogen oxides content. This will not only monitor traffic pollution, save fuel consumption, but also use information calculated from exhaust gas. , allowing drivers to understand their actual impact on the environment and further improve the effectiveness of driving behavior.
On the other hand, smart streetlights are also the key application areas of the Internet of Things in cities. Most countries in the planning of smart cities have the wisdom of streetlights as the Internet of Things because they have power, networking and widespread features. With the necessary infrastructure, the value-added applications that can be carried out are more full of infinite imagination. The common functions of existing smart street lights in various countries include LED energy-saving light control, wireless communication base stations, CCTV, and digital display screens, and some smart street lights are also unique applications that are compatible with their built environment.
For example, San Diego, USA, through the cooperation with AT&T and General Electric, imported 3,000 intelligent street lights from the Intelligent Environments Cities system, equipped with sensors, microphones, and image recognition capabilities, such as parking information, environmental information, and traffic flow. Traffic conditions and other relevant data are immediately transmitted to the cloud platform for analysis. With the energy-saving system, the city saves about 2.4 million U.S. dollars in electricity costs each year. On the other hand, due to the high frequency of gun crimes in the United States, San Diego Streetlight also introduced the gunshot detection function, making the crime more rapid and accurate.
In terms of big data and artificial intelligence, the Tigre Operation Center in Argentina cooperated with NEC to install approximately 1,000 cameras in a range of approximately 400 square kilometers for monitoring, dispatch of police force, environmental monitoring (water level detection), and prevention of panic. , traffic management (traffic prediction) and civic participation applications. With artificial intelligence, the operation center can instantly identify images of people, vehicles, objects, etc., and calculate the number of people in the surveillance area and the degree of congestion. If there is a special event, it can be identified. The system can perform cross-temporal cross-checking to track the behaviors and places of occurrence of locked objects across time and cross-spatial comparisons. In addition, members of the public can use the APP to instantly upload information from all parts of the city and receive messages via Twitter or on Facebook’s label, ElTiger, Operation Center. This function has been gradually applied due to frequent domestic violence in Argentina. Domestic violence briefing.
In terms of AR and VR, Singapore established the Communications Media Development Authority (IMDA) in September 2016, and listed VR development and applications as key projects. Among them, clinical medicine has also become a field of VR experiments. IMDA collaborated with Side Effects of the software company and Houdini, a 3D animation platform. By simulating the surgical environment with VR, medical students can practice the cumulative experience of the surgical procedure and speed up the preparation for actual surgery.
In terms of financial science and technology, although countries have already vigorously promoted digital payments, cash use in most countries is still the mainstream of transactions. Therefore, Barclays Bank of England launches the ContactlessCash service, which integrates the ATM system with NFC technology to provide Android users with mobile phone sensing and cooperation with APP input. The amount and password can be cashed out, eliminating the restrictions that people can only use ATM cards and machines to operate. This will not only speed up the convenience of ATM withdrawals, but also reduce the risk of loss of ATM cards.
While cities in the international community are promoting smart city projects, the projects they focus on are different, but most of them will focus on smart government, wisdom education, smart security, smart health and medical care, smart energy, smart environmental protection, smart transportation, smart buildings, Smart tourism and other areas of development.
The smart government's basic projects for cities to promote smart cities started with e-government, and extended to other types of municipal services. Vertical applications such as transportation, medical care, housing, energy, etc., with public services, have also become cities. The projects that are unavoidable when promoting smart cities, especially transportation, energy, and environmental protection, are the projects with the highest repetition rate. They show that the local governments have different local needs and development characteristics, but traffic congestion and air pollution are still common problems faced by the global cities. .
In addition, more and more city governments have promoted smart governments and increased government efficiency through the power of communications and science and technology. With the changes in the demographic structure, health and medical care have gradually become the unavoidable responsibilities of many urban governments.
In addition to Taipei’s use of the project office as a media integration platform, other counties and municipalities have gradually planned special units to promote smart city business. In the face of the increasingly common Bottom-Up model, companies can make good use of proposal pipelines. Passively participating in the government's plan in the past, they actively proposed solutions to solve urban problems, shortened the time horizon of applying innovative technologies to the public domain, and encouraged the government to maintain innovative thinking through various types of experimental programs.
In addition, because of the advanced information in Taiwan, the people often compare the service differences between cities, and the city administrators face pressures for cross-regional competition. Once there are good solutions, other counties and cities will also quickly replicate, and therefore, the industry It can initially target domestic indicator fields as a preliminary pilot, build successful cases to increase public sector acceptance, further spread to Liudu and Taiwan, and relevant successful experience can also serve as a springboard for overseas export opportunities through international city exchange channels.
