Why smart cities need to become smarter about technology
Cities are experimenting with smarter ways to use technologies to improve the life of citizens, but their projects are fragmented. Is there a better approach?Smart cities need to become more intelligent about the way they control everything, from traffic lights to the distribution of water.
Cities across the world are experimenting with technology to improve the life of their residents, but many are installing technology in a fragmented way.The problem is that smart technology systems have yet to be connected, with a system performing a function in one part of a town separate from a system performing another function in a different area.Chris Harding, director of interoperability at independent IT standards group Open Group, is on a quest to change that. He believes creating smart networks that can talk to each other will open up huge possibilities for using data to improve the lives of citizens.
There are obvious smart city technologies that should be integrated, according to Harding. It makes sense, for example, to link traffic control systems with pollution monitoring systems so cities can control traffic to reduce pollution levels.
The reason smart cities are not more joined up is that city authorities and technology suppliers tend to develop smart technology “from the ground up”. This means they think about what they want to measure and control, install the sensors and the networks, and then the data processing technology, but they don’t think how they can combine networks of sensors across the whole city, said Harding.
“Smart cities are putting smart applications in, but they have not yet got to point where they realise they need to connect their smart apps together,” he added.
As smart technology becomes more common in cities, municipal authorities and technology suppliers will need to develop ways to make their sensor networks work with each other.
There is a risk that cities will face constant disruption, with competing suppliers digging up the streets to install cable networks or deploying tens of thousands of wireless transmitters, unless they can find a way to share infrastructure.
Cyber security will drive collaboration
One factor that will probably encourage cities and their technology providers to take a more integrated approach to networked sensors is the need for better cyber security.
Hackers have not yet replicated The Italian Job, where a criminal gang brought Turin to a halt by reprogramming the traffic signals, but, in one attack in the UK, they did deface electronic road signs, replacing traffic directions with obscenities.
The risks to infrastructure from cyber crime will escalate exponentially as more networks are interconnected.
“Flood control systems could be subverted by hackers, with disastrous consequences,” said Harding.
Protecting citizens’ data
Data protection will become an increasing concern, particularly as the European Union (EU) General Data Protection Regulation (GDPR) comes into force in May 2018.
