A smart city is an urban area using technology and data, such as Information and Communication Technologies (信息与通信技术) and the Internet of Things (物联网), to enhance quality of life, sustainability, and operational efficiency. City operations crucially impacted by smart technologies include transportation, energy, and infrastructure. As cities incorporate these advancements, they evolve into smarter entities. However, defining which cities truly qualify as "smart" remains a debated matter.The concept of smart cities traces back to the 1950s when Los Angeles officials used data and computer programs to identify impoverished neighborhoods. The term gained prominence in the 1990s, evolving to include engagement from residents. Today, smart city solutions address challenges arising from population growth, with two-thirds of the world's population projected to live in cities by 2050.Smart cities are powered by a convergence of key technologies that drive innovation and efficiency in urban living. Information and Communication Technology (ICT) forms the backbone, encompassing data-related technologies for capturing, storing, processing, and transferring information seamlessly (流畅地). The Internet of Things (IoT) establishes a network of physical devices embedded with sensors and connectivity, fostering the collection and sharing of valuable data. Automation plays a crucial role in minimizing human input, enabling cities to respond dynamically to real-time data transmitted by IoT-connected devices. Moreover, the integration of Artificial Intelligence (AI) combines computer science with robust datasets, empowering cities to manage infrastructure efficiently and adopt sustainable practices. Together, these technologies create an ecosystem, propelling smart cities into the future.In smart transportation, IoT, AI, and geolocation (地理定位) enhance real-time data collection to improve public transportation, reduce traffic congestion, and lower carbon emissions. Smart energy management, powered by AI, analyzes data from connected devices to forecast energy consumption, supporting renewable energy integration and mitigating climate change. Smart infrastructure, covering transportation, energy, and utilities like water, employs sensors and connected devices for proactive issue identification. This not only enhances efficiency but also improves residents' quality of life.By embracing these technologies, smart cities become hubs of innovation, addressing contemporary challenges while promoting sustainability and a better urban lifestyle. As technology continues to advance, the landscape of smart cities will likely shape the future of urban living.3. What is the role of smart energy management?A. To reduce traffic congestion.B. To raise residents' salaries.C. To forecast energy consumption.D. To reduce productive efficiency.
