ARTICLE: Raconteur – Three ways to tackle urbanisation

With nearly 70 per cent of the world’s population expected to live in towns and cities by 2050, rapid urbanisation is one of the biggest challenges of our time, putting unprecedented pressure on transportation systems, utilities and the environment. But emerging technologies are affording new, smarter ways to maintain, build and interact with infrastructure in an effort to make urbanisation more manageable 

01 Using existing infrastructure better

So-called smart infrastructure technology uses sophisticated sensors, data analytics, artificial intelligence, machine-learning and cloud computing to better understand the technical and financial performance of infrastructure to determine new insights for its improved use and maintenance in urbanised areas.

Last year, the UK government announced it is developing a digital twin – an online replica of a system or place which through real-time sensor data mimics its behaviour – of key infrastructure across the country. The governmental Digital Framework Task Group believes such data-capturing and sharing could release an additional £7 billion a year of benefits across the UK infrastructure sector.

“Every asset owner is sitting on a goldmine of data,” says Oliver Hawes, head of smart infrastructure at Mott MacDonald, a London-based management, engineering and development consultancy. “Smart Infrastructure is about improving efficiency, making better managerial and operational decisions, and pin-pointing errors before they happen.”

Other cities are already using this technology to great effect. Mott MacDonald is working with Auckland City Council in New Zealand on a project called Safe Swim. The programme improves the accuracy of water quality predictions for 84 local beaches and swimming spots from less than 20 per cent to more than 80 per cent.

Through the initiative, the company, which has just announced a new partnership with Microsoft to create a cloud-based smart infrastructure platform, collects billions of datapoints from strategically placed sensors, creating a digital twin that can monitor atmospheric conditions, urban stormwater and wastewater networks, and the marine environment in real time.

According to Mr Hawes, the technology will enable the municipality to better understand its wastewater networks when considering future investments, as well as improve public health.

02 Transforming urban mobility

One of the most important areas for future infrastructure investment and transformation amid growing urbanisation around the world is utilising emerging technologies for better, more efficient mobility systems for increasingly congested cities.

London-based PLP Labs and Swedish government-funded research institute RISE have just launched a futuristic proposal for an “exhaust-free, non-stop and high-capacity mobility system”.

Called NuMo, for new mobility, the concept features a platoon of autonomous electric vehicles that travel through a dedicated labyrinth of underground, overhead or river-water tunnels, transporting individuals and families non-stop from one place to another.

In the system, cars are controlled by artificial intelligence, connected to the internet of things and unhindered by other traffic or pedestrians, so they can travel at steady speeds, within milliseconds of one another, in a continuous flow.

According to the researchers, the average speed in large cities is decreasing every year, down to 21 km/h in Stockholm inner city, for example. However, with a speed of 30 km/h, each NuMo lane could take 3,600 vehicles an hour, which means theoretically a four-passenger car with one-second headway would offer twice the lane capacity of a 24-metre bus with 120 passengers each minute.

“It’s like a motorway that never stops, but because the cars are autonomous and controlled digitally, they can drive much closer and much more safely, which is the key,” explains Lars Hesselgren, director of research at PLP Architecture. His team are currently creating an economic case study for the project.

Though clearly a future-forward concept, many transport companies are making investments in similar digitally controlled, free-following transport systems that utilise emerging technologies.

Last year, Volkswagen AG announced its intention to develop a “supercomputer to rule the roads” that can “augment the entire mobility system [of a city] and control it with intelligent algorithms which constantly interact with moving objects – a car, a bike, people – to give predictive optimised routing information”.
