The city of the future is a highly interconnected smart environment where people, government and business operate in symbiosis with spectacular improving technologies such as big data, the Internet of Things (IoT), artificial intelligence (AI), robots, drones, autonomous green vehicles, 3D / 4D printing, and renewable energy.

Simultaneously, it is also a place where surveillance is pervasive and data capture is considered permissible by city residents.

At their heart, smart cities are designed to capture massive amounts of data about the population and its patterns, and use it to inform decision making. This information gathering results in what is called big data, and it is essentially gathered via surveillance.

It is collated from a constantly evolving and expanding IoT – encompassing traffic lights and cameras, pollution sensors, building control systems, and personal devices – all feeding giant data stores held in the cloud. The ability to crunch all this data is becoming easier due to rampant growth in the use of devices algorithms, AI, and predictive software.

Singapore is a leading example of a smart city, and is constantly evolving its “city brain,” a backbone of technologies used to help control pollution, monitor traffic, allocate parking, communicate with citizens, and even issue traffic fines. The behavioral aspect is not to be overlooked. Singapore’s “brain” is attempting to modify human behavior – for example, one system rewards drivers for using recommended mapped routes, and punishes those who do not.

Ultimately, Singapore’s planners hope to discourage driving, and guide most commuters to making greater use of public transportation. The city is planning for 100m “smart objects” including smart traffic lights, lamp posts, sensors, and cameras on its roadways, which will be used to monitor and enforce laws.


Essentially the Internet of Things means that everything – and potentially everyone – will become beacons and data collection devices. Hence, after data, the IoT is the second driving force behind the rise of smart infrastructure; in order for everything from air conditioning to parking meters to function in a smart city, the use of microphones, sensors, voice recognition, etc. must be hooked up to the IoT.

Companies and planners are already beginning to explore the possibilities; a case study from India suggests that light poles along the highways can offer both smart city and connectivity solutions. In addition to helping monitor road conditions, the light poles could be fitted as high-speed data connections.

As cities grow in size and importance to the global economy, it will be increasingly important that they adopt the most innovative and forward-thinking design and sustainability ideas. As a smart infrastructure future unfolds, three important new technologies – big data, the IoT and renewable energy – are working in tandem to transform the day-to-day. For example, South Korea is planning an entire network of smart roads by 2020, including battery-charging stations for electric vehicles (EVs) as well as infrastructure to handle autonomous vehicles.

All this data and awareness will enable decisions that make the best possible use of space, fuel, energy, water, electricity, and all resources, with an emphasis on sustainability. For example, a clear priority is being able to anticipate big traffic jams and provide alternate routes to save time, fuel, and reduce impact on the city infrastructure itself. Limiting waste is a very logical outcome and benefit of the merging of big data, AI and IoT which feeds into the rise of smart infrastructure.

There is also a new scientific forecasting tool to predict solar weather, which will make the rollout of solar on smart roads (and in homes) a more feasible option. Eventually, with a growing array of such distributed power solutions, a centralised energy distribution grid for UK homes and businesses may not be necessary.

The smart city movement now afoot has the potential to transform the organisation of people and physical objects in a way that transcends urban development as we know it. The shift to smart infrastructure is not simply fashionable or aspirational; in many ways, it appears to be a critical enabler of the future sustainability of cities. It can be argued that the future of human life on the planet rests on a smooth transition to cities that are more efficient, less wasteful – and more conscious of the impacts of the individual upon the greater good.
