Smart Cities

Smart cities support interdepartmental goals by facilitating shared infrastructure

Instead of working in isolation, municipal departments can share data, such as lighting and telecom needs, seamlessly and collaborate to solve larger-scale problems together. Integrating public feedback systems can further improve city services and sustainability.

Smart city systems can increase positive feelings toward local government

A 2018 study analyzed 50 global cities to determine whether smart city technologies enhance residents' quality of life. It found that these technologies can decrease the time spent interacting with healthcare and government by 45% to 65%, while also decreasing the disease burden by 8% to 15%.

Dubai and Barcelona are examples of smart cities

By integrating technology into public transit, utilities, and other municipal systems, these cities aim to reduce costs and enhance the quality of life for their residents. Some of these technologies include adaptive lighting, parking sensors, and underground waste systems.

In 1974, Los Angeles’s Community Analysis Bureau built a smart city

Los Angeles utilized aerial imaging and cluster analysis to gather and interpret civic data, leveraging surveillance technologies developed by the Department of Defense during the height of the Cold War. Instead of being used for military purposes, data insights helped direct social services to high-poverty neighborhoods.

EXTREMA is a smart city system protecting residents from heat-related health risks

The mobile application is designed to protect citizens in select European cities from extreme temperatures by calculating the heat index at a specific location and providing personalized information to users. Municipal governments can also utilize it to inform emergency responses, such as determining when and where to open cooling centers.

IBM helped turn Rio de Janeiro into a smart city before it hosted the World Cup

In response to the deadly floods and mudslides in 2010, Brazil and IBM developed a multimillion-dollar plan to modernize Rio's emergency management infrastructure. An operations center utilizes advanced weather forecasting, surveillance, and real-time data to surveil and respond to events such as severe storms more accurately.

Connected technology improves infrastructure efficiency in smart cities

Through information and communication technologies, smart cities can provide enhanced public services and improved quality of life by managing traffic and dynamic safety policies. They can also promote sustainability by automating energy use and redirecting resources according to need.

Many issues facing urban environments cannot be solved by smart technologies

Although connecting systems to the Internet of Things can provide improved efficiency in municipal systems, problems such as limited affordable housing are driven by larger socioeconomic factors. Some experts suggest that local governments should focus resources on practical solutions to these issues rather than investing in smart technologies.

The Internet of Things connects everyday objects to the internet

The IoT enables physical devices to share data collected via sensors or specialized software, often without human intervention. Controlling the air conditioning and heating in one's home via an app, as well as receiving alerts when away from home about someone at the door, is made possible by the IoT.

As of 2025, there are no federal laws involving privacy and smart city technologies

Advancements in cloud technology and artificial intelligence allow cities to capture, store, and analyze more information than ever before. Experts warn that the unhindered ability to collect and use this data may infringe on residents' rights and endanger them if the data gets into the hands of malicious parties.
