The new phase of smart city development is what we are witnessing currently. Growing urban mobility demands powerful solutions for keeping the urban system sustainable. This is where IoT stands out as an advanced tech that can help plan cutting-edge smart cities with improved quality of life, better transit systems, and more energy-efficient city infrastructure.
Not only does IoT-integrated tech boost social connectedness and improve how the city operates, but it also saves lives with cleaner air, faster transit to medical facilities, and fewer cases of unfortunate incidents or mishaps. 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.
| Energy Savings | Saving of Commute time | Faster Emergency response time |
| Fewer Crimes | Saved Lives | Lower Disease burden |
| Lower water consumption | Better Water/Air Quality | Enhanced Economic growth |
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:Â 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
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
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
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
Crime Monitoring & Anticipation
Urban Agriculture
Noise Pollution Control
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.
