Our growth challenges in cities globally are becoming more complex. Now more than ever, we need new solutions and creativity to help us shape more resilient and sustainable cities in the future.
For the first time in history, we have access to dynamic urban data to understand people’s collective behaviours in real time. If used, this expansive evidence base can help planners, designers, and decision-makers make more informed decisions about the future of our cities.
However, the timing dilemma is an obstacle in harnessing this data. While urban environments typically develop every 50 years, technology moves more rapidly, significantly improving every five years, creating a disparity between urban planning and urban living.
So how does the planning industry keep pace with digital technology to create sustainable outcomes? One way is to improve our relationship with the digital world and put trust and confidence in digital tools and innovative solutions.
Why should planners trust data and digital?
Our cities are where urban planning and living come together. They are a super ‘neural network’ of interrelated systems. To create intelligent, responsive cities, urban development must embrace new possibilities using data and the internet of things (IoT).
Technology and data have never been more available. As a result, urban planning has a massive opportunity to unleash its full potential by investing more time and resources into harnessing data and digital planning.
Tools like the ‘digital twin’ are likely to become an indispensable part of future ‘urban infrastructure’, enabling the seamless integration of the ‘physical’ and ‘digital’ worlds and redefining how we plan.
Similarly, digital master planning is a framework to test thousands of options based on various variables and parameters to test failure, resilience, adaptative pathways, optimal living conditions, human health and welling, energy efficiency and more.
The planning industry must adapt to this changing paradigm, by matching the efforts and confidence invested in building the cloud system and IoT coverage, or risk being left behind.
To create intelligent, responsive cities, urban development must embrace new possibilities using data and the internet of things (IoT).
How Arup planners are using the power of digital
Projects worldwide show the value and credibility of digital tools to create growth and provide sustainable outcomes.
Cities urban tree canopy is a critical component of green infrastructure providing comfortable environments and reducing heat. Arup’s leading Urban tree canopy analysis used is a study for the City of Gold Coast, which uses a computer algorithm to determine the percentage of vegetation cover over different time intervals to show canopy changes.
Terrain is Arup’s bespoke artificial intelligence and land use analysis tool. It harnesses the power of data analytics, machine learning and automation to accurately digest large quantities of data and satellite imagery. Using this tool, we calculated seven cities' sponginess by measuring the green and blue infrastructure areas to understand how cities can better use this infrastructure to face increasing threats from climate change – including heavy rainfall and extreme heat events.
Another Arup tool is the City Algorithm Tool (CAT) which tests hundreds of growth scenarios using different development and community value parameters to determine optimal outcomes for urban living. For example, Smakkelaarsveld in the Netherlands used algorithms to optimise the scheme design against multiple KPIs, including sustainability and environmental objectives.
Similarly, digital master planning can test site and precinct options based on various variables and parameters to test failure, resilience, adaptative pathways and optimal living conditions.
The last example, solar analysis helps test hundreds of layouts and orientations to achieve optimal living conditions and thermal comfort. For example, for Mahindra World City Jaipur, we used solar assessment tools to determine the optimal orientation for the plots and streets to provide thermal comfort in a hot climate.
Small risks, great rewards
Trust in the planning process is the foundation for our cities to take the best path to sustainable growth. Taking small, calculated risks in improving our digital capabilities now can lead to great rewards for our cities.
Speed and efficiency, automating tedious and repetitive tasks and allowing more design and collaboration time.
Test 3D scenarios, assessing hundreds or thousands of options during the planning process against agreed parameters or criteria.
Facilitate approval process, comparing design scenarios with consented planning schemes and existing site conditions for faster agreement on key issues.
Identify client priorities; testing many possibilities can help identify what is most important.
Improve participatory design; with more data, we can understand community needs and improve community engagement.
We help cities keep pace with the digital world
Masterplanning and Urban Design
We design sustainable places in balance with the aspirations of communities. Integrated urbanism, Arup’s approach to masterplanning, acknowledges the interdependence of urban systems and communities as well as the effects of global issues, such as climate change resilience and economic uncertainty.
