Researchers Seek To Facilitate Smoother Evacuations
July 2, 2018

June marks the advent of the 2018 hurricane season. In anticipation of violent storms arriving, government agencies such as FEMA, scientists and first responder organizations across the country are searching to discover how to facilitate smoother evacuations from impacted areas. Based on information provided by Embry-Riddle Aeronautical University (Embry-Riddle), a team of professors and graduate students, funded as part of a consortium by a sub-grant from the Center for Advanced Transportation Mobility, are studying Hurricane Irma’s mass evacuation to provide recommendations for a smoother exodus in the future.

As millions of Floridians heeded warnings following the state of emergency declaration and the call for mandatory evacuations, highways, interstates and the Florida Turnpike quickly turned into parking lots as people sought to find safe shelter before the powerful Category 4 storm made landfall. In the process, vehicles and gas stations ran out of fuel leaving fleeing motorists stranded and causing gridlocks.

The Embry-Riddle study, which will continue through February 2019, will provide an analysis to the U.S. Department of Transportation (DOT) on Irma’s evacuation and fuel shortages that occurred. The team on Embry-Riddle’s Daytona Beach Campus will identify opportunities and vulnerabilities that currently exist; make policy recommendations for more efficient future evacuations; and suggest how to improve allocation of resources and better equip areas to avoid fuel shortages.

“If you know in advance which areas will be hardest hit, priority treatment can be given to refueling those gas stations,” noted Sirish Namilae, Ph.D., assistant professor of Aerospace Engineering and principal investigator on the project along with co-principal investigator Dahai Liu, Ph.D., professor with the School of Graduate Studies, and their graduate students Sabique Islam and Dimitrios Garis.

“By conducting simulation runs within specified parameters, we hope to get a better picture of what occurs when the masses are forced to move along a particular path and how it affects them,” said Garis, an Aeronautics master’s student working with professor Liu. “We hope this research will provide emergency evacuation planners with an idea of what can be done to help speed up traffic flow and ensure evacuees make it out of the danger areas faster.”

Dr. Namilae is adapting a particle dynamics mathematical model that he and a previous team developed to study pedestrian movement and ways to reduce the spread of infectious diseases on commercial airlines and at airports. Algorithms will be derived that will help provide real-time data during future evacuations. The team will perform a detailed case study of evacuation out of Florida from Miami-Dade County on Interstate 95, Florida’s Turnpike and Interstate 75.

“This research uses a combination of theories and ideas borrowed from different avenues of science such as disease transmission modeling, sensor fusion algorithms from aerospace engineering and probability of random numbers from computational mathematics,” said Islam, a graduate teaching assistant studying Aerospace Engineering. “The outcome will help teach future researchers to employ different methods to their research and have an open mind when it comes to attacking scientific problems from different aspects.”

“We are looking at whether fuel restrictions placed on cars could help to get more cars out, since during a hurricane there are limited supplies for each gas station and gasoline cannot be delivered to gas stations promptly due to traffic constraints,” Prof. Liu explained. “This type of situation is hard to investigate as it involves many factors that are complex and studies are extremely limited.”
