Key Takeaways

• Large language models (LLMs) like ChatGPT can boost urban planning productivity but may lead to job losses.
• AI can reduce planners’ administrative burdens, allowing more focus on community engagement and long-term strategies.
• Guidance is needed to manage AI’s risks, particularly regarding biases and subjective planning decisions.

AI in Urban Planning: Opportunities and Challenges

Recent research published in Nature Cities highlights the potential of artificial intelligence (AI) to transform urban planning. Experts indicate that large language models (LLMs), such as OpenAI’s ChatGPT, can serve as valuable resources for planners by managing local data and streamlining report drafting. However, concerns have been raised regarding the impact on employment, as these technologies could potentially displace certain jobs.

Lead researcher Dr. Xinyu Fu from the University of Waikato emphasizes that while AI can augment planners’ abilities, it is crucial not to view it solely as a job replacement. Dr. Fu’s research indicated that urban planners spend significant time on administrative functions—tasks that LLMs can handle more efficiently. For instance, during a pilot project with Hamilton City Council, the AI analyzed thousands of public submissions in hours, a process that traditionally takes human planners months.

The Australian government has acknowledged the need to improve productivity, with Treasurer Jim Chalmers underlining it as a key economic issue. A Productivity Commission report cites record numbers of Australians working longer hours, suggesting that AI could alleviate some of the pressures on urban planners, allowing them to engage more with communities and devise long-term policies.

The Planning Institute of Australia (PIA) recognizes AI as one of four primary forces reshaping urban planning, alongside climate change and demographic shifts. Nicole Bennetts from the PIA noted that while AI could streamline low-risk tasks like development assessments, the complexity of many planning decisions necessitates human intervention to ensure nuanced judgment.

AI’s integration into urban planning is already ongoing, with councils in Victoria and Queensland experimenting with AI tools for various tasks. Nevertheless, experts caution against the risks of reliance on AI, particularly regarding bias in data. As Bennetts pointed out, AI systems trained solely on past decisions may fail to incorporate new information, such as climate projections, complicating decision-making processes.

Professor Toby Walsh from the University of New South Wales AI Institute suggests that AI adoption in planning could lead to fewer jobs but argues this should not be the sole focus. Instead, he advocates for leveraging AI to enhance public responsiveness and engagement in planning processes.

To effectively manage the challenges posed by AI, especially concerning regulation, Walsh believes that the Australian government must take a leading role, similar to its actions with social media. While the European Union has initiated AI regulation, Walsh stresses the need for a tailored Australian approach that balances innovation and safeguards for the public.

Overall, AI has the potential to revolutionize urban planning, enhancing efficiency and responsiveness despite the challenges it presents, particularly regarding job displacement and decision-making complexities.
