Analyzing Dynamic Shifts In Fatality Risk Factors In Transportation Construction

Abstract

Despite improvements in safety protocols, fatalities in the transportation sector remain significantly higher than in other industries. They stem from a mix of demographic, environmental, and occupational risk factors. Although research has explored contributing elements, there is a notable gap in understanding their evolution over time. This study aims to analyze the changing patterns of fatality-associated factors within transportation construction. A three-stage methodology was adopted. First, data from the US Census of Fatal Occupational Injuries, consisting of 3,792 fatal cases with 12 features and 630 categories, was preprocessed. Second, the Apriori algorithm was applied, identifying key contributing factors. Lastly, a change mining analysis examined temporal shifts across three demographic groups over three timeframes, identifying evolving risk patterns. Findings show that among white males, the most critical risk factors - being an unskilled laborer, working in the private sector, and being struck by mobile equipment - declined in significance, possibly due to safety interventions. For males of other races, risk patterns shifted from pickup truck accidents involving young, short-tenure employees to work zone incidents in large firms in the South. Among females, the predominant risks - directing traffic and working as crossing guards - remained consistent. These insights support data-driven safety improvements.
