  1. This project presents methodology to analyze high resolution connected vehicle data (CVD) for understanding how movements of populations during pandemic-hurricanes impact disease spread and devising better plans for safe sheltering and evacuations of vulnerable populations. The dataset contains historical vehicular movement data of for Florida Panhandle Counties of Calhoun, Escambia, Liberty, Gadsden, Jackson, Santa Rosa, Washington and Bay that are impacted by Hurricane Sally which made landfall on September 16, 2020. This coincided with the first phase of the Covid-19 pandemic. The datasets used for this study consist of GPS movement data, shelter and lodging facility wait time, and vehicle count data for 44 shelters and 123 lodging facilities in Florida’s Santa Rosa, Escambia, and Okaloosa counties from 01 to 30 September 2020. The dataset has been used in the following publications: Tsekeni, D.E., Alisan, O., Yang, J., Vanli, O. A., Ozguven, E.E., (2025) “Spatiotemporal modeling of connected vehicle data: An application to non-congregate shelter planning during hurricane-pandemics”, Applied Sciences, 15, 3185. DOI: 10.3390/app15063185. Tsekeni, D.E., Vanli, O. A., (2025) “Time Series Segmentation of Movement Network Data for Endemic-Epidemic Modeling of Infectious Diseases”, IISE Transactions on Healthcare Systems Engineering, (Submitted, May 2025)

  2. Urban resilience is a multifaceted concept including the recovery of the physical infrastructure and various urban activities that depend on that physical infrastructure. It is relatively straightforward to quantify infrastructure resilience by tracking the recovered facilities in time and marking the time that the infrastructure is fully functioning again. However, the physical infrastructure recovery does not necessarily indicate that the urban activities bounce back to the predisaster conditions. The restoration of urban activities depends on the areas that a particular infrastructure serves (e.g., residential, commercial) and the connections with other critical facilities (e.g., health, education). It is important to investigate the infrastructure recovery and “resilience divide” with respect to the enabled services and affected populations in order to achieve all-inclusive resilience. For this purpose, we examined the resilience of different physical elements such as power feeders (i.e., underground or overhead lines), critical facilities (e.g., fire and rescue services, hospitals) and different socio-demographic segments of the population (i.e., different age groups, ethnicities, and income levels) which constitute an urban environment. The analyses were conducted using the power outages experienced after Hurricane Hermine in Tallahassee, as a case study. The findings show that overall resilience performance can be distinct and/or not homogeneous for the resilience of different physical elements, urban services, and population groups.
