Geographical Information Systems-Based Assessment of Evacuation Accessibility to Special Needs Shelters Comparing Storm Surge Impacts of Hurricane Irma (2017) and Ian (2022) Yang, Jieya; Kocatepe, Ayberk; Alişan, Onur; Ozguven, Eren Erman (2025-03-01) Research on hurricane impacts in Florida's coastal regions has been extensive, yet there remains a gap in comparing the effects and potential damage of different hurricanes within the same geographical area. Additionally, ...
Spatiotemporal Modeling of Connected Vehicle Data: An Application to Non-Congregate Shelter Planning During Hurricane-Pandemics Tsekeni, Davison Elijah; Alişan, Onur; Yang, Jieya; Vanli, O. Arda; Ozguven, Eren Erman (2025-03-01) The growing complexity of natural disasters, intensified by climate change, has amplified the challenges of managing emergency shelter demand. Accurate shelter demand forecasting is crucial to optimize resource allocation,...
An Analysis of the Spatial Variations in the Relationship Between Built Environment and Severe Crashes Alişan, Onur; Ozguven, Eren Erman (2024-12-01) Traffic crashes significantly contribute to global fatalities, particularly in urban areas, highlighting the need to evaluate the relationship between urban environments and traffic safety. This study extends former spatia...
Large-scale modeling of hurricane flooding and disrupted infrastructure impacts on accessibility to critical facilities Alam, Md. Shaharier; Kim, Kyusik; Horner, Mark W.; Alişan, Onur; Antwi, Richard; Ozguven, Eren Erman (2024-04-01) Post -hurricane accessibility to critical facilities is crucial for accelerating the recovery process, which can often be disrupted by hurricane-induced flooding. The State of Florida is especially vulnerable to flooding a...
Understanding Changes in Spatial Accessibility to Restaurants During the COVID-19 Pandemic: Disentangling Closures, Inequity, Neighborhood, and Transportation Mode Kim, Kyusik; Horner, Mark W.; Alam, Md. Shaharier; Alişan, Onur; Ghorbanzadeh, Mahyar; Ozguven, Eren Erman (2024-04-01) Among one of the more significant societal impacts of the COVID-19 pandemic, restrictions on people's movement accelerated, and in some cases outright caused, restaurant closures. By considering people's potential for both...
Assessing Tornado Impacts in the State of Kentucky with a Focus on Demographics and Roadways Using a GIS-Based Approach Kaya, Mehmet Burak; Alişan, Onur; Karaer, Alican; Ozguven, Eren Erman (2024-02-01) Although the literature provides valuable insight into tornado vulnerability and resilience, there are still research gaps in assessing tornadoes' impact on communities and transportation infrastructure, especially in the ...
Rapid simulation of storm surge inundation for hurricane evacuation in Florida by multi-scale nested modeling approach Vijayan, Linoj; Huang, Wenrui; Ma, Mengdi; Ozguven, Eren; Yang, Jieya; Alişan, Onur (2023-12-01) Hurricane evacuations require fast updates of coastal inundation predictions based on the update of hurricane forecasting track. NOAA usually updates the hurricane track at about 6 h interval. This paper presents a multi-s...
Traffic monitoring system design considering multi-hazard disaster risks Gazzea, Michele; Miraki, Amir; Alişan, Onur; Kuglitsch, Monique M.; Pelivan, Ivanka; Ozguven, Eren Erman; Arghandeh, Reza (2023-12-01) Roadways are critical infrastructure in our society, providing services for people through and between cities. However, they are prone to closures and disruptions, especially after extreme weather events like hurricanes. A...
Understanding spatiotemporal variation of social vulnerabilities from longitudinal hurricane-pandemic data: A multilevel model of the Covid-19 pandemic during hurricane Sally in Florida Abazari, Seyedreza; Vanli, O. Arda; Alişan, Onur; Ozguven, Eren Erman (2023-11-01) An important question in the context of compound disasters is the degree to which geophysical disasters amplify the transmission of infectious diseases during pandemics and how this relation-ship is influenced by the socia...
Measuring spatial accessibility of public libraries using floating catchment area methods: A comparative case study in Calhoun County, Florida Takyi, Samuel; Antwi, Richard B.; Ozguven, Eren Erman; Alişan, Onur; Ghorbanzadeh, Mahyar; Mardis, Marcia; Jones, Faye (2023-11-01) Public libraries are critical facilities that provide a variety of essential services to the public such as providing access to information, resources, sheltering and gathering space during natural disasters such as hurric...
