Artificial Intelligence study demonstrates rapid walking pace increase and reduced social interaction in three urban areas

In a groundbreaking study, AI technology has been used to analyze footage of parks and plazas, providing insights into the evolution of public spaces over the years. The findings reveal a shift in behaviour, with people walking faster, standing still less often, and interacting less frequently compared to the 1970s.

The decline in social interactions may be attributed to factors such as accelerating work rhythms, the increasing value of time, and the influence of technology like smartphones. However, this trend is not without consequences. Public spaces offer unique opportunities for social interaction and cultural exchange, and their diminishing use poses a risk to these vital aspects of community life.

AI technology can be a valuable tool in addressing these issues. It can be used to study public spaces from the 1970s and compare them with recent videos in the same locations, taking minutes instead of months as was previously required. This analysis can help architects and urban planners understand the changes that have occurred and suggest improvements, such as the design of furniture, greenery, or water features that promote interaction.

The city of Zurich provides a compelling example of this evolution. From 1970 to 2010, the city experienced a significant transformation of its public space, influenced by urban development, social changes, and evolving technologies. The study, published in the proceedings of the National Academy of Sciences, highlights the need for cities to adapt public spaces to changing climates, as temperatures rise across southern Europe.

AI technology can also be used for stewardship, observing how people actually behave, testing hypotheses, and prototyping joy and proximity in public spaces. For instance, temporary design interventions can be introduced, evaluated with AI, and iterated to evolve organically, much like nature itself.

However, it is crucial that architects use AI tools with humility. They should acknowledge the past flaws in public space design and avoid a technology-led approach that might repeat the mistakes of high modernism. Instead, AI should be used as a tool to counter the hollowing of public space and help preserve the fragile, elusive symphony of the commons.

Moreover, the study in Milan found that compliance with speed limits has more to do with street geometry than signage, suggesting that AI can be used to optimise public spaces in ways that might not be immediately apparent.

In conclusion, AI technology offers a powerful tool for understanding and improving public spaces. By analysing behaviour patterns, suggesting improvements, and observing the impact of interventions, AI can help ensure that public spaces remain vibrant, interactive, and relevant in a rapidly changing world.
