By Melodie Roschman Faculty of MathematicsA team of undergraduate Computer Science students placed in the top eight at a recent AI Hackathon with “Skyline,” a project that uses demographic data and machine learning to simulate cities and use these patterns to optimize its transit infrastructure.
The four students – Rajan Agarwal (Software Engineering), Elijah Kurien (Software Engineering), Ishaan Dey (Software Engineering) and Joshua Yan (Computer Science) – were able to attend the hackathon, which took place from June 22 to 24 at the University of California – Berkeley, thanks to sponsorship from the Math Endowment Fund. “We had two goals,” Agarwal says: “to represent Waterloo on an international stage, and to learn more about the connections between machine learning, math and calculus.”
The friends, who are currently doing co-op terms with tech companies in Berkeley, San Francisco, Palo Alto, and Toronto, are united by their passion for AI, and their desire to use the technology responsibly to make people’s lives better.
When it came time to decide on a project, the team realized quickly that they had to prioritize their values to be successful. “At first, we were asking what was going to win, but then we realized that was the wrong mindset,” Agarwal says.
“We needed to work on something we enjoyed and were motivated to work on. We’re all really interested in modeling how humans think and reason and we also have useful experience in different fields. For example, I’m currently working at Hitachi Rail, and I have a lot of experience thinking about transit and urban planning. With that in mind, we decided to try to simulate human behaviour within Los Angeles.”

Over the thirty-six hours of the hackathon, the team gathered demographic data from the Los Angeles city government, then built more than 2,000 AI profiles of people of different demographics who would then travel through their simulated version of LA. They then built a machine learning model that analyzed the various options for transit routing and optimized them to allow people to travel efficiently while also minimizing carbon emissions.
The result of their work, “Skyline,” was a hit with the judges, particularly in the AI for Good and AI for Climate categories.
Ultimately, the team were chosen as “grand finalists,” placing in the top eight projects among more than four hundred teams. Though the team enjoyed the recognition that came with being finalists – dinner with OpenAI co-founder Andrej Karpathy – they say that they’re most grateful to have found a project they’re passionate about.
Skyline, the team hopes, could be adapted for use by urban planners and city governments in other cities as well, potentially reducing carbon emissions from transportation by as much as 18 per cent. Now back in Waterloo, they’re continuing to develop the research begun at the hackathon as part of their co-founded Human Simulation Lab. Though the Berkeley hackathon was sponsored by venture capitalists, and the team has been approached by investors interested in monetizing the technology, Agarwal says they’re more interested in research than profit.
“This is a situation where we’re not trying to replace humans, but to empower them,” Agarwal says. “In this industry, we have to be careful that we’re using this technology not to control or exploit people, but rather to contribute to human flourishing.”

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
