What is a smart city?

According to IBM, a smart city is an “an urban area where technology and data collection help improve quality of life as well as the sustainability and efficiency of city operations.” Technologies used by smart cities include digital twin technology, information and communication technologies (ICT), and Internet of Things (IoT).

1. Improved traffic management

Smart cities can use digital twins to revolutionize traffic management by creating dynamic, real-time simulations of traffic flow. These simulations help optimize traffic signals, routes, and public transportation systems. With digital twin technology, cities can predict congestion patterns, reduce traffic bottlenecks, improve commute times, and lower vehicle emissions, contributing to a more efficient and sustainable urban environment.

For fast-growing cities, effective traffic management is critical as populations expand and infrastructure is stretched. “Rapid growth often leads to increased congestion and longer commutes, which can overwhelm city services,” says Anne Eskola-Hickey, Chief Growth Officer at Younite. “Implementing smart traffic solutions allows cities to handle increased demand without costly infrastructure projects such as large freeway expansions." By optimizing traffic flow and public transportation, cities can prevent bottlenecks, improve mobility, and support sustainable urban development.

Example: In Chattanooga, Tennessee, the Digital Twin Project has been used to mitigate traffic congestion. Completed in 2022, the project developed a scalable traffic management framework to address the challenges of heavy traffic on two interstate highways, which together handle over 250,000 vehicles daily. By using digital twins, Chattanooga optimized its existing road networks without the need for costly infrastructure projects like bypasses or ring roads.

2. More efficient resource management

Smart cities are addressing the urgent need for resource management by integrating digital twins and smart technology to optimize energy and water usage across infrastructure. With increasing concerns over water scarcity and climate change, cities must find innovative ways to conserve resources and manage their infrastructure more effectively. Digital twins allow cities to create virtual models that simulate energy consumption, identify inefficiencies, and manage renewable energy resources in real-time. This enables more effective resource allocation, reduced waste, and a sustainable approach to urban development.

Example: In Barcelona, the city's smart water management system has seen remarkable success by implementing IoT-based technologies. Using a network of sensors and smart meters, the city collects real-time data on water usage, leak detection, and distribution efficiency, reducing operating costs by removing the need for manual meter readings. This system has also reduced water loss by 25%, ensuring that the city can conserve its resources while meeting the needs of its 3.3 million residents. With water scarcity becoming a global issue, such smart city innovations are essential to ensuring the sustainability of urban environments.

Another key advantage of Barcelona’s smart water management system has been reducing meter reversal fraud. Previously, detecting this required costly field visits, with only 20% of cases validated due to insufficient evidence. With smart monitoring, fraud can now be detected remotely and immediately, eliminating the need for inspections.

3. Increased urban safety

Smart cities can enhance their public safety by offering a comprehensive view of urban infrastructure, helping identify vulnerabilities and simulate emergency scenarios. Cities can develop more effective response strategies to emergencies such as natural disasters, fires, or crimes.

Example: Warner Robins in Georgia implemented its Citizen Safety Digital Twin to enhance public safety. Supported by a Partnership for Inclusive Innovation grant, the digital twin project uses dynamic license plate reader cameras in optimal locations to improve crime prevention efforts. As a result of this project, Warner Robins was recognized with the Smart21 Community Award at the 2024 Taipei Smart City Summit and Expo, an honor awarded to only 21 cities worldwide.

4. Enhanced accessibility and inclusion

Smart cities also have the potential to address the diverse needs of all residents by improving accessibility and inclusion. From barrier-free infrastructure to intelligent navigation tools, smart city technologies can help ensure that public services and spaces are more accessible to individuals regardless of physical abilities, language, and more. Additionally, many services can be offered virtually, reducing the need for physical visits. For example, virtual access to a public park or city museum can provide experiences that may not be possible in real life. 

Example: As part of the Networked Local Digital Twins programme, the European Union is encouraging cities to join forces and explore what they can achieve with digital city twins. Younite is a proud member of this initiative. By using AI-powered avatars that meet the needs of diverse target groups as they explore cities, Younite is working to improve accessibility and inclusion in city services.

The economic growth and innovation driven by smart cities is transforming urban landscapes worldwide. By integrating advanced technologies like IoT and digital twins, smart cities are creating new opportunities for efficiency, job creation, and investment across various sectors.

1. Increased cost savings

Smart city technologies optimize the use of resources such as energy, water, and transportation. As we saw with Barcelona, cities can reduce operational costs and improve infrastructure management through real-time data and automation. “Think smart streetlights that adjust based on traffic conditions to lower energy consumption,” shares Anne Eskola-Hickey, “or digital twins that allow cities to simulate various scenarios—such as extreme weather or surges in demand—to prevent costly infrastructure failures and further increase long-term savings.”

2. Job creation and economic expansion

The development of smart cities spurs growth in emerging industries like data analytics, sensor manufacturing, and urban technology solutions. This not only creates jobs but also drives local economic expansion. As smart cities become more technologically advanced, more and more businesses and industries are drawn to these hubs, further enhancing the local economy and fueling innovation.

A recent study on smart city pilots in China revealed that smart city initiatives greatly promote employment, particularly in sectors like technology development and public services. The implementation of digital technologies in smart cities not only supports job growth in these areas but also helps optimize employment structures by encouraging a shift toward service-oriented jobs. 

3. Attracting talent and investment

Smart cities offer enhanced infrastructure, sustainability, and quality of life, making them attractive to top talent and forward-thinking companies. By offering enhanced public services, efficient transportation, and modernized infrastructure, smart cities create an environment where skilled professionals want to live and work.

A recent study on the impact of digital technology in 20 Italian cities over an 11-year period demonstrates a direct relationship between the implementation of digital solutions and the influx of talent and forward-thinking businesses. Similarly, in the United States, Younite has been collaborating with urban development and real estate companies, giving them a competitive edge by allowing investors and potential clients to visualize the future of their cities. Through a city’s digital twin, stakeholders can explore proposed developments and provide feedback.
