IoT in smart cities can keep the city safe, prevent accidents, and also enable real-time surveillance for the prevention of crimes. Cleaner cities have lower disease rates, less burdened healthcare, and easy access to medical facilities.

Let us dwell deep into the impact, use cases, and benefits, of advanced IoT-based solutions for Smart Cities. The article also details top IoT applications, best practices for their implementation, and the future of smart cities that deploy IoT solutions.

Smart Cities and Their Impact

Smart cities can respond better to the needs of their residents. They improve the quality of life, happiness index, and life expectancy by optimizing the resources, space and infra that residents share.

As Forbes defines it: “A city that has developed a public-private infrastructure to support energy, transportation, water resources, waste management, smart building technology, security operations, sustainability, and citizen services is referred to as a "smart city".

Smart cities impact multiple facilities, areas, and layers within the city like its mobility (speed and safety of transit), energy efficiency and delivery, water quality and accessibility, healthcare facilities, waste management, and security. If all the above are delivered, then the outcome is robust economic development and a higher living standard index.

There are more job and business opportunities, reduced cost of living, and more well-being due to social connectedness.

However, the effectiveness of these impacts is dependent on how the city is able to integrate three key elements:

Smart technologies like IoT, AI, and analytics. Smart itself signifies digital adoption and implementation.

Specific applications and software that are capable of using smart and advanced tech like IoT (IoT-enabled software apps)

Public Usage: There should be awareness among people and users of these technologies and apps. For instance, if sensors and apps can alert a driver within a city about a roadblock or closure but the driver doesn't use the app or hasn't downloaded a city-provided app then the tech and apps are of no use.

• With an annual CAGR of 19%, the global IoT in smart cities market is bound to touch new highs and will become a 300+ billion dollar market just by 2026.
• In 2023, there were 15.9 billion IoT-connected devices, the number is set to become 39.6 by 2033.
• Industries like electricity, A/C, waste management, and water supply power over 100 million IoT devices each.
• Smart City Expo World Congress, the world’s biggest event for cities and urban innovation predicts that 70% population will live in smart cities by 2050.

Use Cases and Applications of IoT in Smart Cities

The Internet of Things (IoT) in urban landscapes of smart cities transforms outdated, inefficient, and energy-consuming processes into intelligent, efficient, and lean processes with interconnected ecosystems. The results of implementing IoT apps and solutions in smart cities are improved sustainability, better quality of life, and huge savings in terms of energy and water. Improved urban planning & waste management with IoT also improve the green cover and reduce diseases.

Real-time public transit optimization

IoT-enabled traffic signals can analyze real-time traffic conditions, adapt to traffic peaks and lows, and help reduce traffic jams. E-hailing (Private and Pooled) IoT enables efficient e-hailing services by connecting passengers with available vehicles in real time. This technology reduces overall traffic congestion by promoting carpooling. Smart coordination of traffic lights has the potential to cut average travel times by over 5 percent.

IoT sensors embedded in parking spaces can provide real-time information on available parking spots. This leads to the smart circling of vehicles that prevents parking woes. It reduces parking search times and congestion

Smart surveillance

Advanced videos and IoT-integrated cameras can recognize license plates or are even embedded with facial recognition tech. Cameras and sensors can monitor environmental conditions, dam water levels, river currents, and weather events. IoT-based early warning systems can detect natural disasters like earthquakes, floods, or tsunamis, providing crucial extra minutes for evacuation. Smart home security systems with IoT can provide real-time monitoring and alerts and ensure residential safety in smart cities.

Water management

Climate change is making water availability unpredictable. Increasing scarcity of water, decreasing underground water levels, and continuous water pollution are issues that are common in urban areas. Further, issues like water waste and supply disruptions can financially burden a city. This is where IoT can help smart city water departments optimize their water management processes.

A sophisticated water management system also integrates AI and big data technologies with IoT devices. Smart sensors can monitor the health of water equipment (pumps and pipelines) and detect problems like pipe leaks. IoT sensors also monitor levels of chemicals or toxins in water. Detecting water pressure levels, salinity, humidity, etc. is easier with IoT.

Energy management & saving

Adopting IoT in energy management will reduce electricity consumption by over 1.6 PWH in 2030. IoT devices have smart sensors that know when to adjust settings based on occupancy or time of the day (ex. Smart thermostats, smart lights, smart ACs, etc). Smart HVAC systems use IoT sensors to monitor air temperature, humidity levels, etc. IoT sensors can detect maintenance issues in energy-consuming devices and systems. All these measures greatly reduce electricity wastage.

Consequently, an intelligent street lighting system can instruct a streetlight to adjust its brightness, and turn on, or turn off the lights as per requirements. For example, when people walk across the street, the lights near the crossings can automatically switch to a higher brightness level.

Pollution control

IoT-based smart city technologies can detect and evaluate real-time environmental factors such as the Air Quality Index (AQI) to learn about air pollutant concentration, air quality, air pressure levels, etc. These sensors can send alerts to city administration or nearby industries to take corrective actions if AQI surpasses the threshold limits. The City of Newport in Wales, UK, deployed IoT solutions to improve air quality, flood control, and waste management.

Waste management

Cities with unorganized garbage collection systems or no method of monitoring landfills or waste collection are prone to higher risks of diseases among their residents. There should be a system to monitor fill levels in bins or the presence of hazardous chemicals in bins. This is where IoT sensors fitted bins can help.

These bins can send alerts to waste collection services about their fill levels and help the services better plan their collection routes and priorities. It saves effort, fuel, and time. IoT-fitted smart waste sorting systems can automatically separate recyclables, compostables, and landfill waste.

Healthcare monitoring

While smart traffic management already makes healthcare access easier for every resident and reduces emergency response time, IoT-enabled medical-grade wearables can further reduce the need for healthcare services. IoT devices can monitor citizens' vital signs, suggest exercises, send alerts on exertion, tell them when to rest/sleep, and keep them fit.

These devices can also be used to send alerts to emergency services in case of health crises. Smart ambulances equipped with IoT can transmit patient data to hospitals en route. This leads to faster treatment upon arrival.

Smart Buildings

IoT sensors fitted in apartments, residential homes, commercial buildings, etc. serve many purposes. They can help in smart electricity consumption, monitor appliances for optimal usage, and detect any structural issues in buildings. Smart elevators use IoT to predict maintenance needs. The IoT can also monitor indoor air quality and adjust ventilation systems accordingly.

Crime Monitoring & Anticipation

Smart cities with IoT-based predictive policing features can anticipate criminal activities by identifying crime patterns, crime hotspots, and suspicious activities with sensors and surveillance cameras. IoT-enabled acoustic sensors can detect gunshots and alert law enforcement.

Urban Agriculture

Rooftop gardens are great for improving microclimate factors. However, their maintenance and nurturing require time and effort. Automated systems fitted with IoT devices can send alerts to residents for watering, fertilizing, changing lighting conditions, etc. IoT systems can also change the rooftop awnings to keep optimal sunlight levels for the plants.

Noise Pollution Control

IoT acoustic sensors can monitor noise levels across the city. This data can be used to identify noise pollution-sensitive areas, hotspots, and extremely noise-polluted areas. This can help city administration decide on routing traffic, set horn limits, set noise level restrictions for pubs, dance clubs, construction sites, open event grounds, etc.

Smart Tourism

IoT-enabled tourism enhances visitor experiences while optimizing city resources. Smart beacons and NFC tags on historical landmarks can provide interactive, multilingual information to tourists' smartphones. The Internet of Things (IoT) can improve safety protocols for tourists with its advanced monitoring and emergency response mechanisms. IoT establishes a networked environment for smart decision-making for both service operators and tourists.
