In this feature Rohit Talwar, Steve Wells and Alexandra Whittington present their view of the city of the future.

The city of the future will be human, smart and sustainable – in the coming decades, the planet’s most heavily concentrated populations will occupy city environments where a digital blanket of sensors, devices and cloud connected data are being brought together to enhance the city living experience for all. Smart concepts encompass all of the key elements that enable city ecosystems to function effectively – from traffic control and environmental protection to the management of energy, sanitation, healthcare, security, and buildings.

Purpose, Engagement and Vision

In a fast-changing world, it can be hard to develop a clear future vision and strategy – when every sector is being disrupted and all our assumptions are being challenged. However, that’s exactly what we have to do. City governments must create inclusive processes that inform citizens about the forces shaping the future and then engage the population in dialogue about the kind of future we want to create.

Alongside this we need to articulate a clear vision and direction around education, environment, public services, access to justice, city administration, and civic engagement. These pillars then provide the guiding requirements which will in turn influence the design of the physical, digital and human elements of a smart city infrastructure.

Observation and Surveillance

Smart cities are designed to inform decisions by capturing massive amounts of data about the population and its patterns, such as water use and traffic flows. This information gathering results in what is called big data, and it is essentially gathered via surveillance. The data can be collated from a constantly evolving and expanding Internet of Things (IoT) – encompassing traffic lights and cameras, pollution sensors, building control systems, and personal devices – all literally 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 – all running on networks of high performance computing and storage devices.

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. 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. The city is planning for 100 million “smart objects” including smart traffic lights, lamp posts, sensors, and cameras on its roadways, which will be used to monitor and enforce laws.

Always Connected

Smart cities rest on advanced technology to make sense of massive collections of information. Essentially IoT means that everything (“things”) – and potentially everyone – will become beacons and data collection devices, gathering data on ambient and behavioral patterns from its surroundings and from the information it is fed—and networking all this data via the cloud. Hence, after data, the IoT is the second driving force behind the rise of smart infrastructure; for everything from air conditioning to parking meters to function in a smart city, the use of microphones, sensors, voice recognition, and all sorts of other high-tech gadgetry must be hooked up to the IoT.

Companies and planners are already beginning to explore the possibilities. For example, 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. Data is a critical element of the smart city/smart road future. However, because this option will further expand the relationship between internet service providers, surveillance, and private business including advertisers, there are several issues around privacy to be considered.

Driving Smart Cities

In general, the concepts around smart cities, smart roads, and smart infrastructure are becoming less visionary and more strategic and sustainable by the day. 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. Autonomous vehicles will require roads to transform into information superhighways; the vehicles will need to communicate not only with each other, but also with the city infrastructure. The need for ubiquitous data is a critical step in the evolution toward self-driving cars. Mapping, traffic signals, and safety regulations, for instance, are all parts of the physical and digital infrastructure that will have to become highly coordinated for autonomous vehicles to function.

Low-Impact Strategies

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 priority is being able to anticipate big traffic jams and provide alternate routes to save time, fuel, and reduce impact on the city infrastructure. Limiting waste is a logical outcome and benefit of the merging of big data, AI and IoT.

Electric vehicles are growing their market foothold, however, one of the biggest hurdles to electric vehicle adoption is keeping a charge across long distances. To help address this challenge, UK researchers are testing out smart road technology that charges electric cars while they are being driven. The achievement of smart infrastructures could drive the required policy and behavioral tweaks to enable wide adoption of today’s renewable resources.

A futuristic concept that would not require sunshine is the capture of renewable energy with piezoelectric crystals installed beneath asphalt on busy highways. Theoretically, the crystals could capture the energy released by vehicles driving over the asphalt, which could then be stored or used for powering highway infrastructure. Piezoelectric crystal pilot programs, though so far unsuccessful, provide a fresh perspective on renewable options for gathering energy to power our infrastructure and roads.

A Human Future

The smart city movement has the potential to transform the organization 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 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. This may include a range of new negotiations along the boundaries of freedom and privacy; for example, allowing self-driving cars to replace human drivers in the hope of preventing death and injury in auto accidents, increasing traffic efficiency and removing environmental impacts. Similarly, we might have to agree to invasive monitoring of waste generation, energy and water use in the home to reach municipal conservation goals. These are the kinds of tensions that future planners will need to wrestle with on a continuous basis.

A well thought through vision, enabled by a robust and well-executed smart city model could provide a foundation stone for the next stage of our development, where science and technology are genuinely harnessed in service of creating a very human future.
