Pattern Recognition from Rail Grade Crossing Fatal Crashes

Rail grade crossings (RGCs) or highway-rail grade crossings are the locations where a road segment and railroad track intersect at a joint. RGCs generate a range of transport, economic, social, and environmental impacts. Safety at RGCs is one of the high-priority concerns among transportation agencies. However, little research has been performed on the patterns of key contributing factors associated with RGC crashes. The aim of this study is to identify the patterns of key contributing factors that are associated with RGC related fatal crashes. This study collected nine years (2010-2018) of fatal RGC crashes from the Fatality Analysis Reporting System (FARS) to perform the analysis. To do so, this study Taxicab Correspondence Analysis (TCA), the current analysis identifies several key clusters that trigger RGC related fatal crashes. The key clusters are extremely fatal (more than one fatality) impaired crashes during inclement weather, fatal crashes local low-speed roadways at dark with no lighting, aligned county roadways, single fatal non-impaired crashes, crashes on multilane divided roadways due to turning/stopping, and crashes on high speed state highways when negotiating a curve. The findings from the current study can be used by authorities to improve RGC safety.
