SEPTEMBER 23, 2024 — Two UTSA researchers will participate in a collaborative project to advance research and education in urban digital twins (UDTs) and responsible artificial intelligence (AI). The project aims to improve the resilience of communities, especially those of color, by leveraging these technologies to address the urban challenges they face.
UTSA faculty members Wei Zhai and Esteban López Ochoa in the UTSA School of Architecture and Planning and the university’s Center for Urban and Regional Planning Research will collaborate with Xishuang Dong, an assistant professor of electrical and computer engineering at Prairie View A&M University and the project’s principal investigator. Additionally, Xinyue Ye, urban planning professor and director of The Center for Geospatial Sciences, Applications, and Technology at Texas A&M University, will contribute to the project, which will offer UTSA students a unique hands-on learning experience.
Community resilience refers to how well a community is equipped to persist during adverse events, such as natural disasters, economic downturns and public health crises, and to how quickly the community recovers once the situation stabilizes.
“As urbanization accelerates, urban communities — particularly those predominantly comprised of racial and ethnic minorities — face unique and complex challenges, weakening the resilience of the community," Zhai said. “These include increased poverty rates, displacement, relocation, limited access to quality education, disparities in healthcare access, and substandard housing conditions.”
The project aims to alleviate these challenges by using responsible, foundational AI models and tools to create urban digital twins.
A digital twin is a virtual model of an object or system that uses real-time data to simulate, monitor or predict behavior. Digital twins can operate with ongoing, two-way data, making them the most precise way to represent a city and its actual systems.
The project leads hope to create an urban digital twin that will simulate an urban community and analyze its resilience and weak points.
“A digital twin of a city offers planners and citizens a powerful tool for understanding how changes in planning and infrastructure can impact a community’s resilience to natural hazards,” Zhai said. “By digitally modeling and testing various resilience scenarios, planners, policymakers and citizens can identify the most effective, science-based strategies for hazard resiliency interventions. The platform will gather vast amounts of data, including information on people, vehicles, structures and infrastructure, enabling the simulation of hazard events under different policy or response scenarios to assess their potential impacts.”
Zhai added that the project’s ultimate goal is to develop innovative solutions to address urban challenges.
“Digital twins can provide the insights needed to inform resilient decision-making in vulnerable communities,” he said. "We’re examining the LiDAR sensor and low-cost environmental sensor technologies, artificial intelligence, mechanisms and policies needed to increase community resilience.”
The team will use the data collected with these tools for 3D modeling of cities and micro-climate simulations.
Modeling multiple facets of a community accurately and in real time can be challenging, as communities involve multiple interconnected elements. Those elements include the people, infrastructure and environments, which influence one another in a complex feedback loop.
“During a severe storm, for example, predicting human behavior is difficult,” Zhai said. “Some residents may follow evacuation orders, while others might stay behind to protect their homes, even though it's risky. This unpredictability complicates resource allocation. It’s hard to determine the number of emergency shelters needed or how many rescue personnel are dispatched. Additionally, panic or misinformation could lead to unexpected traffic jams or crowding in specific areas, further complicating emergency response efforts. Incorporating these unpredictable human behaviors into a real-time model adds significant complexity.”
The team hopes that a digital twin powered with AI will be able to cut through these layers of uncertainty, providing valuable insights that help policy makers anticipate needs and plan for challenges.
“This project can help to better visualize and predict long-term resilience risks such as population growth, housing and transportation demand, and all the various urban issues that can come from such core changes,” López Ochoa said. “For example, understanding how, when and why people move to a new home within the city can help both explain and address issues such as job absenteeism, delays, lack of labor supply, food deserts and even housing affordability.”
In the process, the team also hopes to integrate AI into new research projects and academic programs at UTSA, engage students in leading-edge research and cultivate a workforce with in-demand skills such as AI, urban planning and data science.
“We are excited to offer UTSA students funded opportunities to work on urban research that is at the knowledge frontier,” López Ochoa said.
The team plans to study San Antonio and Houston initially then expand the digital twin modeling to other cities across Texas in subsequent phases. The project began in September 2024 and will continue until August 2027.
The National Science Foundation (NSF) awarded the project $1 million, which includes a subaward of $293,000 to the UTSA team.

Downtown CampusThere are many citation managers. Which one is right for you? This workshop will explain what a citation manager is and how it can help you organize your citations, insert citations as you write your paper, and generate your bibliography. If you plan to attend one of our hands-on Endnote®, Zotero®, or BibTeX® / LaTex® workshops, we recommend that you start with this overview.
Virtual EventJoin us for a recital featuring a variety of Hispanic music from Spain and Latin America. The evening’s entertainment will include pieces by UTSA faculty, the UTSA Mariachi Los Paisanos, and special guest artists including the director of Texas A&M International University's Mariachi Internacional.
UTSA Recital HallJoin Dr. Rachel Yvonne Cruz, Assistant Professor of Mexican American Studies, for an interactive discussion on how music can challenge patriarchy, sexism, and colonialism through a guided discussion and live acoustic performance.
Assembly Room, 4th Floor (4.04.22), John Peace Library, Main CampusIn this hands-on workshop, participants will learn to setup an EndNote library, save references and PDFs, and automatically create and edit a bibliography. Attendees are encouraged, but not required, to have EndNote already installed on a personal computer.
Virtual EventAre you required to use LaTeX for writing your research papers? This workshop is divided into two parts: an introduction to Zotero, a citation management tool, and a demonstration of the features of Overleaf, a free online LaTeX editor.
