The IoT Brings Smart Cities to Life
In around 30 years, planet Earth will be home to almost ten billion people, 68 per cent of which will live in urban areas. And those urban areas will face a torrent of problems, as authorities will have to rely on limited resources to provide public services to a growing number of citizens. Besides traffic congestion and the potential rise in crime rates, rapid urbanization could also lead to a number of environmental problems like air pollution and overwhelmed waste collection systems. To tackle these challenges and make cities more liveable and manageable, governments are increasingly turning to the smart city concept.
At the heart of this approach is the use of technology to improve public services such as transportation, water systems, waste disposal, and many others. And among all the technologies smart cities deploy, the Internet of Things stands out as the most important, as it’s a network of sensors and connected devices that collect data critical for understanding how urban areas function. As Stephen Brobst, the chief technology officer of Teradata, a big data analytics company, says, the IoT enables us to “get a view of the whole city across these different domains of the life of the city as it’s captured in the sensor data.”
The many ways in which the IoT helps smart cities
Investments in smart cities are ramping up across the world and are expected to grow from $80 billion this year to $135 billion by 2021. Part of that money is allocated for IoT projects that help governments and residents to increase energy efficiency, improve traffic flow, reduce pollution, cut costs, and enjoy a number of other benefits. In other words, the IoT helps smart cities to achieve many of their key goals. Take, for example, the problem of traffic congestion in cities, which is in large part caused by drivers looking for parking space. IoT sensors embedded into the city’s streets, as in the case of Barcelona, can detect empty parking spots and alert drivers through a smartphone app. This helps people park their cars faster, saving time and fuel while reducing harmful emissions.
Many smart cities also tend to promote bike-sharing services as a way to reduce pollution and congestion, but bike theft could be an obstacle for that plan. One way IoT tech can help solve this issue is through technology such as Bitlock, a keyless bike lock that’s unlocked by the user’s smartphone and tracks the GPS location of the bike. This will help police potentially track and recover stolen bikes, while also allowing private and public organizations to analyze bike traffic patterns and find ways to improve the service.
IoT technology is also efficient in tracking and analyzing water use in buildings. For instance, Banyan Water, a smart water management company, claims it’s helped customers to save more than seven billion liters of water since its inception in 2011. The way it does this is by placing sensors and ultrasonic meters that track water consumption across the building, using software to analyze the gathered data and find anomalies such as leaks and overspend.
