Spatial Analysis of Rural Crashes and their Effect on Crash Severity

Abstract: From 2012 to 2016, Louisiana experienced 3,302 fatal crashes along its roadways. Among those fatal crashes 1,472 involved alcohol and 1,423 crashes involved no seatbelt use. The LSU Highway Safety Research Group through the use of GIS Network Analyst has been investigating the spatial analysis of rural crashes and exploring the contributing factors, such as alcohol and seatbelt use, which affect crash severity. By examining distance of crash location to the nearest hospital we are able to further investigate the injury severity outcomes of rural vs urban crashes in Louisiana.

Jeff Dickey and Bethany Campbell - will be presenting co-presenting. Bethany joined HSRG as a GIS Specialist in April of 2013. Prior to joining HSRG, Bethany worked for the Louisiana Local Technical Assistance Program producing GIS Mapping Analysis. With an educational background in planning and graphic composition and a degree in Landscape Architecture from LSU, her work at HSRG involves the development of various crash data visualization formats and GIS Mapping. Jeff Dickey received his PhD in Geography from Florida State University. He is engaged in Geographic Information Systems (GIS) research, GIS support for the LACRASH system, and spatial analysis of crash data. Dr. Dickey’s recent projects include spatial analysis of seat belt use in crashes, a GIS model of projected consequences from storm surge inundation, and spatial analysis of alcohol involved crashes.
