Spatiotemporal Modeling of Transportation-related Data
Transportation-related data is generally spatially and/or temporally correlated. We focus on the development of statistical models that can appropriately account for the spatiotemporal dependence of transportation-related data and to make more reliable inferences.
Resilience of Transportation Systems
Over the years, we have seen that extreme weather events such as hurricanes are becoming more frequent and severe. Great efforts are expected to mitigate the impacts of extreme weather events, adapt to adverse situations through effective emergency management, and develop operational plans for fast recovery after disruptions.
Analysis, Modeling, and Prevention of Secondary Crashes
Secondary crashes or crashes that occur within the boundaries of the impact area of prior, primary crashes are one of the incident types that frequently affect highway traffic operations and safety. Our studies explored the mechanisms of secondary crashes and provided insights into preventing secondary crashes and mitigating their impacts.
