What Is a Smart City? Definition and 6 Examples

Urbanization needs optimization. By 2050, 2 in 3 people across the world will live in cities, which will leave a strain on city resources. Although cities generate much of the world’s wealth, many cities aren’t prepared for their rapid growth. According to C40, 75% of all global energy consumption occurs in cities.

Smart cities could be the solution. A smart city model uses modern information and communication technology to improve its infrastructure, share information with the public and provide a better city living experience.

Smart City Technologies

Smart cities are implementing smart technologies in everything from street lamps and drones to robotics and building information modeling (BIM). And that’s just the beginning. The growth of the Internet of Things (IoT) is what makes smart cities just that — smart.

IoT describes the network of physical objects that use sensors, software, and other technologies to connect and exchange information with other systems by using the internet. Smart cities use such devices to collect and analyze data to improve infrastructure, public utilities, government-provided services, and the overall city life experience.

In fact, the value of IoT in smart cities is expected to reach $735 Billion by 2030, proving that cities are eager to embrace new tech that promotes sustainable growth.

Characteristics of Smart Cities

Collaborating with big-name developers like IBM, Microsoft, and Cisco and innovative startups, smart cities can track valuable data like weather, traffic, and resources. Then, they use it to optimize their energy use, utilities, safety, transportation, waste management, and public services. Let’s take a closer look at some of these smart city features.

6-examples-of-smart-city-characteristics

Safer Streets

Connected street cameras, body cameras, and commercial vehicles’ dashcams are all monitoring activity and sharing data in real-time. This data gives first responders and city officials the information they need to easily detect, respond to and prevent road accidents, violations, traffic jams, and even potholes.

Improved Infrastructure

In smart cities, an improved infrastructure allows resources to go further and allow for heightened safety preparedness. For example, resources like garbage collection can only be stretched so far in a typical city, making trash collection inaccessible for many. However, some smart cities are now using waste sensors to detect garbage levels and determine who needs garbage pick up and who doesn’t. Doing this allows garbage collectors to maximize their collection routes and serve more businesses and homes.

But improved infrastructure doesn’t stop with city services. It also allows for better city safety and structure, like structural sensors and smart earthquake detection to warn the public about incoming natural disasters well before they hit.

Better Utilities

Every home and business needs access to tap water, but what if your city went above and beyond to test and monitor it? Or what if the city monitored water levels, so city officials could become immediately aware of water leaks? This is a reality in some smart cities.

City lighting is also becoming increasingly smarter and more cost-effective, with LED lamp posts that adjust their brightness depending on the time of day and the weather conditions.

Smart cities are also adopting a “smart grid,” where energy consumption is analyzed to offer optimal electricity supplies at the right time to the right places.

Healthier Environment

Using air pollution sensors, smart cities can effectively monitor carbon dioxide (CO2) emissions and car pollution. This monitoring allows city dwellers to redirect their traffic flow to avoid breathing in toxins, airborne illnesses, and other pollutants that can be detrimental to a person’s health.

Improved Transportation

Smart cities are all about efficiency. For many, transportation is a considerable efficiency waster. But with improved transportation methods like driverless cars, smart parking meters, and real-time traffic monitoring, people in some smart cities are getting time back in their day when they no longer have to waste time sitting in congested areas or looking for an open parking meter.

Prioritized Public Safety

If a city is striving to make itself more liveable, it has to guarantee better law enforcement and emergency response to increase public safety. Smart cities are using emergency cameras to give dispatchers and first responders optimal routes to scenes like car accidents, fires, natural disasters, crime scenes, and other emergencies. Smart city features are always evolving as cities adapt and adopt new technologies.

How Does a Smart City Work?

Smart cities use four key elements to become more livable as larger amounts of people continue to move to urban areas.

  1. Collection: Real-time data is collected by smart cameras and sensors.
  2. Analysis: Data is analyzed to understand and identify pain points and what can be improved.
  3. Communication: Once data is collected and analyzed, solutions are proposed to decision-makers and city officials.
  4. Action: Action plans are put in place to improve the quality of life for the city population.

These elements are the stepping stones to the innovations we see in smart cities today. As cities incorporate this methodology, city living across the world can become smarter, more sustainable and more efficient.

Smart City Challenges

While the goal of a smart city is to make city living more accessible, making these large-scale updates and using tech that collects and shares large amounts of data can come with plenty of challenges along the way.

Here are five main challenges and concerns people have with smart city initiatives:

  1. Transparency: Collected and shared data must be accurate and shared in real time.
  2. Availability: Cities are responsible for installing sensors and smart cameras, but must also offer a reliable way for individuals and businesses to receive the data.
  3. Integrity: Data must not be manipulated by officials to paint the city in a more positive light.
  4. Confidentiality: Some collected data may not be intended for public consumption. Cities are responsible for keeping sensitive data private and secure from outside attacks.
  5. Accountability: Cities are responsible for who sees what data and how it’s used. Where there is highly-sensitive data, user logs should be enforced to ensure accountability for who accessed the data and how they plan to use it.

The Importance of Smart Cities

Big cities are becoming more aware of their growth. For example, London, England is projected to be home to 9.8 million people by 2043, an increase of 800 thousand people when compared with 2021. With that amount of growth, current cities do not have what it takes to make city living habitable.

Smart cities use intelligent technology, connected devices, and instantaneous data to solve real-world problems. From reducing energy use to alleviating traffic congestion, smart cities are positively changing the lives of urban residents worldwide.

Countries, towns, cities, and governments have realized the potential and impact of smart cities. Investment in smart cities is rapidly growing, as global spending on these revolutionary initiatives and digital technologies are expected to hit $2.6 trillion worldwide by 2026. Additionally, construction jobs in cities across the U.S. are booming to meet this demand.

With cost, sustainability, and efficiency benefits, smart city technologies are no longer part of the distant future. They are quickly becoming essential for cities to thrive and support a healthy, ever-growing population.
