As cities strive to become smarter and more efficient, the Internet of Things (IoT) has emerged as a crucial part of the smart city blueprint. In this blog, we will explore the role of IoT in the smart city, and how it is helping to transform urban environments by connecting devices, collecting data, and driving intelligent decision-making.
With advancements in IoT and sensor technology, inspectors can monitor the structural health and performance in real time of assets such as bridges, roads, and buildings. This non-destructive monitoring allows for predictive maintenance, enabling proactive repairs and reducing downtime, so disruption is kept to a minimum for users, while increasing overall safety.
One of the biggest problems any city has is traffic management, and the additional pollution it creates. In a smart city however, IoT devices allow for intelligent transport systems, optimizing traffic flow and reducing congestion. In Hong Kong’s Smart City Blueprint, for instance, the government plans to install 1,200 traffic detectors along all major roads to provide real-time traffic information. The data collected is disseminated to road users via an app and the relevant authorities to make more informed decisions on routes, and facilitate the smoother running of traffic.
Another major issue for cities worldwide is waste management, environmental health, and carbon emissions. IoT technology is not only helping cities optimize energy consumption through devices such as smart electric meters, it also enables authorities to monitor air and noise pollution, so the data can be collected, analysed, and preventative measures undertaken. Waste management is another area being revolutionised through IoT. Companies such as GF Technovation in Hong Kong, are spearheading the implementation of smart bins around cities. Seen in action below, these smart bins have fill level alerts to notify waste collectors when the bin is ready to empty so they can optimize their collection routes. They also have solar-powered trash compactors to optimise capacity, and can even extinguish fires if detected.
People like to feel safe when they are out and about. Smart cities promote a safer environment by using IoT-connected CCTV systems, facial recognition, and video analytics to improve safety for citizens, disaster management and crime prevention. IoT-connected CCTV systems, along with facial recognition, and video analytics allow public spaces to not only be monitored in real time, but can also automatically detect anomalies and alert the relevant parties for a quicker response. The data collected is also very useful for authorities to investigate incidents, and for better planning and resource allocation.
We can see that IoT is a crucial part of the makeup of a smart city. As its use grows, citizens will enjoy greater convenience, more accurate information, and a cleaner environment.
