With the continuous advancement of human society, future cities will accommodate an increasing population. China is currently undergoing rapid urbanization, and issues like "urban diseases" such as traffic congestion, pollution, and resource shortages are becoming more pronounced. To address these challenges and achieve sustainable urban development, building smart cities has become an inevitable trend in global urban development.
**What is a smart city?**
As information technology continues to evolve, the application of digital tools in urban settings has significantly improved. Smart cities represent a new stage in urban development, offering great potential for sustainable growth, technological innovation, and enhanced city competitiveness. While there is no universally accepted definition, a smart city primarily focuses on optimizing the management, operation, and service of urban resources to improve the quality of life for its residents.
Today’s smart cities leverage advanced technologies such as the Internet of Things (IoT), cloud computing, and big data to support government operations, business activities, and daily life. The core goal is to achieve efficient, intelligent, and precise management across all urban sectors. This includes integrating critical systems like transportation, communication, water supply, and energy to reduce waste and enhance infrastructure efficiency.
A smart city is essentially a fusion of the physical and digital worlds, using digital platforms, IoT, and cloud computing to enable real-time perception, control, and intelligent services for people and objects. It aims to create a more harmonious relationship between humans and nature by driving economic transformation, improving public services, and promoting sustainable urban growth.
**How to Build a Smart City: 3 Smart City Projects**
**1. Smart Trash Cans**
Philadelphia has been using BigBelly solar-powered trash cans since 2008. Initially installing 470 units, the number increased to 900 by 2011. These bins can compress waste up to five times their capacity, powered entirely by solar energy. They alert operators when full, reducing the frequency of garbage collection from twice a day to once a week. This results in lower fuel consumption and fewer emissions.
Philadelphia claims annual savings of around $800,000 due to this system. While some argue about cost-effectiveness, smart trash cans can be particularly beneficial in high-traffic areas like shopping centers or parks. The cost per unit is approximately $4,000, making it feasible to start with a small pilot project.
**2. Smart Street Lights**
Los Angeles has replaced 80% of its 210,000 street lights with smart LED lighting, saving $9 million annually in energy costs. These lights also offer additional features like 4G LTE connectivity, Wi-Fi hotspots, and security cameras. Each smart light can reduce grid load, allowing for more electric vehicle charging stations.
The initial installation cost was $57 million, but with falling LED prices, the payback period has shortened. A small pilot project with 10 lights could cost around $1,500, making it a practical starting point for cities exploring smart infrastructure.
**3. Smart Parking Meters**
Portland, Oregon, installed 7,000 smart parking meters between 2002 and 2005, boosting parking revenue by over $2 million. These meters support credit card payments and send alerts to drivers’ phones when their time is about to expire. They also provide real-time updates on available parking spaces through mobile apps.
While some drivers may be reluctant to pay higher fees, the system helps reduce illegal parking and fines. A pilot project with 10 meters could cost around $15,000, offering a manageable entry point for cities looking to modernize their parking systems.
**New Smart City Construction Becomes a National Strategy**
As China continues to urbanize, the challenges of environmental pollution, traffic congestion, and resource scarcity have become more pressing. Addressing these issues requires a shift in urban development strategies. At the 2017 Huawei ICT Silk Road Changan Forum, Hong Xiaozhou, a leading expert in smart cities, emphasized the importance of a new model for smart city development.
Since 2008, smart city initiatives have evolved from enterprise-led efforts to national-level projects. In 2013, the Ministry of Housing and Construction launched the first batch of 90 smart city pilots, followed by other ministries launching their own programs. By 2015, a new coordination working group was established to promote unified standards and integrated development.
Smart city construction is now a national strategy aimed at improving urban management, enhancing public services, and supporting sustainable development. It reflects China’s commitment to modernizing cities through digital innovation and green practices.
