AI City Planning: Enhancing Urban Spaces with Artificial Intelligence
According to researchers at Tsinghua University, AI city planning has proven to be significantly more efficient and effective than traditional approaches. Led by Yu Zheng and his team, the study aimed to assess whether a machine learning model could create a space that aligns with the 15-minute city concept. The results were impressive, with the AI program producing a plan in a matter of seconds, a task that typically takes human planners between 50 to 100 minutes.
Our public spaces play a crucial role in shaping our daily lives, influencing our access to essential services such as healthcare and groceries. However, designing cities that provide high-quality communities has become increasingly challenging as our population continues to grow. Fortunately, artificial intelligence holds great promise in expediting and improving city planning to create better living spaces in the future. In this article, we will delve into Tsinghua University’s groundbreaking AI city planning study and explore the additional benefits of utilizing artificial intelligence in shaping urban environments.
How did an AI plan a city?
The researchers at Tsinghua University sought innovative solutions to address the growing congestion and environmental issues in cities. Their response was the creation of an AI program capable of automating the tedious and computational aspects of urban planning. Here’s how the system worked:
Yu Zheng and his colleagues instructed the model to design urban spaces spanning a few square kilometers or roughly 3×3 blocks. Through extensive training using neural networks, the AI system learned to search for optimal road layouts and land uses that aligned with local planning policies and the 15-minute city concept. The latter involves facilitating easy access to essential city destinations like offices and supermarkets by foot.
The results were remarkable, as the AI model completed tasks that usually take humans 50 to 100 minutes in mere seconds. Their workflow, aided by AI, increased access to basic services by 12% and parks by 5%. However, the researchers acknowledge that the program has limitations, such as its inability to design an entire city. Scaling up to a 4×4 block size requires twice as many planning decisions as the 3×3 model.
Nevertheless, automating time-consuming planning tasks can save significant amounts of time, allowing human planners to focus on more human-centric aspects. By leveraging AI, planners can engage with the public, prioritize aesthetics, and tackle more complex challenges. Tsinghua University envisions their AI system as an assistant to urban planners, generating concept designs and optimizing them with algorithms for review, adjustments, and evaluation with community feedback, an integral step in ensuring proper design.
How can artificial intelligence improve smart cities?
Chris Chiancone, Chief Information Officer of Carrollton City, highlights how AI tools can revolutionize smart city planning. For instance, AI can simulate multiple versions of a city to meet various requirements. An AI city planner can prioritize nature parks or enhance accessibility to public amenities like schools and hospitals. Furthermore, the program can predict a city’s growth and transformation over time, providing valuable insights for informed decision-making on infrastructure design and resource allocation.
AI can also be instrumental in improving existing cities. Through data analysis, AI tools can suggest suitable locations for new roads, extensions to public transportation, or the establishment of new public spaces. Generative AI, the technology behind ChatGPT, can uncover correlations and patterns that human planners may overlook. For example, it may identify a connection between the location of public parks and the improved health of nearby residents.
Real-world examples of AI city planning already exist. Cities like Amsterdam and Singapore have utilized generative AI to simulate future urban scenarios. With the rapid advancement of artificial intelligence, AI city planning may soon become the global standard, leading to more livable urban areas compared to existing ones.
