Intelligent cities rely on sensors that gather, monitor and analyze data to provide actionable insights for driving operational efficiencies, engaging citizens and increasing economic viability.
Singapore uses IoT cameras to track public spaces, crowd density and registered vehicle movements. Furthermore, they are testing autonomous vehicles as well as having a system in place to protect senior citizens.
Infrastructure
Smart infrastructure enables a city to collect, analyze and disseminate data on various aspects of urban living environments in order to make better-informed decisions on operational and asset management matters.
Technology-enabled cities are increasingly adept at meeting these challenges efficiently and effectively, from traffic signal optimization to managing sensitive health-care information such as illness trends. Evolving technologies enable cities to address such obstacles more effectively.
New York City recently implemented smart city infrastructure by replacing 6,400 payphones with interactive kiosks that provide free Internet connectivity and allow residents to report issues directly with city officials – such as streetlight outages or any other issues with streetlights – directly. Residents also report streetlight outages directly, saving problems from becoming worse or exorbitantly expensive; first responders benefit from real-time crime and traffic data which helps speed response time; other examples of smart city infrastructure include public transit, parking optimization and air quality sensors – which all help reduce emissions while making cities more sustainable.
Energy
From traffic lights and powering city services, water management, waste collection, communications networks and smart city technologies that enable seamless interactions between citizens and local government are complex systems that need advanced solutions for successful operation. Smart city technologies deliver useful, responsive services while improving interactions between citizens and local government.
Smart cities provide more environmentally sustainable models of rapid urbanisation by harnessing renewable energy sources and using efficient systems to decrease power consumption and mitigate greenhouse gas emissions. Intelligent transportation systems that optimise road networks and increase traffic flow help commuters avoid bottlenecks. Meanwhile, smart buildings offer energy-saving HVAC systems, lighting controls, and insulation measures designed to reduce energy consumption. Other smart cities utilize advanced waste management systems to minimise landfill use and encourage recycling, while providing real-time data that enables municipal officials to monitor operations more easily and make informed decisions for the future of a city.

Security
Smart city networks must not only ensure all devices work as intended, but must also secure any data collected. They must protect against cyber attacks that could destabilise critical infrastructure systems or jeopardise public safety – for instance a parking meter could be hijacked to submit false traffic management reports.
Effective smart city IoT solutions must deliver actionable information in real time, which means implementing security solutions capable of protecting data availability, integrity, and confidentiality.
Since smart cities handle both open and closed data, such as touristic information and healthcare records, a multifaceted approach to network security is necessary. This requires using strong encryption protocols and segmenting networks effectively; all devices should also have sensors capable of detecting tampering or falsification that enable quick detection so as to stop malicious activity spreading further.
Sustainability
Sustainability measures and procedures implemented within smart cities aim to foster economic development and enhance quality of life by employing advanced technologies to reduce energy use, pollution levels and waste production; traffic congestion may be decreased while providing residents with better services like public Wi-Fi networks or e-bike rental programs.
While many of these systems can be immensely helpful, they cannot replace the cultural aesthetic that draws residents in and fosters an aesthetic sense of place. Therefore, for smart city design to ensure sustainability it must incorporate social factors that ensure sustainability.
Though urban sustainability is one of the cornerstones of smart city literature, few definitions explicitly address it. Most focus on environmental and social aspects, with only a few providing economic-oriented definitions; those focused on economic sustainability tend to downplay its social aspect in favor of economic growth; this stands in stark contrast with how both are linked within smart city models themselves.
