Urban traffic simulators are used by cities worldwide to inform their transportation planning and operations. We discuss the main challenges in the calibration of inputs for stochastic microscopic urban traffic simulators. In particular, we focus on the calibration of travel demand or origin-destination matrices (ODs). The problem is underdetermined, we… read more 

Urban life has been increasingly grounded in mobilities as technological advances induce faster, cheaper, and more seamless mobility options. However, people’s experiences of such advances are shaped by their race, gender, class, other socially constructed dimensions, and the intersections of these dimensions. Despite the growing popularity of intersectionality lens, quantitative… read more

The decline in commercial districts in Seoul, South Korea, is worsening because of excessive competition among the self-employed, COVID-19, and a decrease in offline consumption. Assessment of this decline is the first step in presenting strategies for the revitalization of commercial districts. This study explored whether cognitive decline can be… read more

Big data and computational algorithms have gradually become integrated with the built environment and within human’s daily lives, leading to a significant rise in Urban Artificial Intelligence (AI) research and applications. As such, the proposed Design & Analytics system will develop digital twins and virtual/augmented reality for multi-scaled simulations and… read more 

This talk focuses on data science-enabled scientific discoveries and Artificial Intelligence techniques for urban systems in adapting to the changing climate. Cities around the world are facing various physical, social, and economic challenges associated with many stressors such as climate disasters. What makes cities vulnerable is in large part due… read more 

People are the most important part of cities. However, digital twins tend to focus on buildings and infrastructure. Dr. Rosenheim will introduce a project that provides a solution that connects people to buildings for digital twins. The housing unit inventory method transforms aggregated population data into disaggregated housing unit data… read more
