PURPOSES : In this study, the factors influencing traffic accidents of commercial vehicles in the transportation industry were examined. The evidence observed in this study showed how it contributes to the establishment of safety management policies. METHODS : Safety management data obtained from the Korean Transportation Safety Authority were integrated. A multi-regression analysis was performed by comparing data for the past three years of traffic accident data. RESULTS : Through multi-regression analysis, items that significantly influenced the safety evaluation index (the number of traffic accidents per vehicle owned and the number of dangerous driving actions per 100 km per person) were analyzed. Items with similar patterns observed for various commercial vehicle industries were also analyzed. Monthly average drop off rate, number of law violations per driver, percentage of drivers above 65 years old, percentage of drivers that have completed the compulsory education, number of vehicles owned, and driving distance per vehicle are the variables that influenced the safety evaluation index. CONCLUSIONS : There is a growing need to establish safety management policies and management measures to enhance the voluntary safety management capabilities of the industry. Safety management should be conducted through the analysis of traffic accident impact factors for commercial vehicles.
