Sažetak
The construction industry experiences numerous accidents of varying severity. This study analyses 434,134 occupational accident records from the construction sector in Turkey (2012–2021) using ordinal logistic regression for four-category severity modelling. Unlike previous studies, the dataset was split into 70 % training and 30 % independent test sets. The model achieved a classification accuracy of 56.0 %, demonstrating strong sensitivity in identifying rare, high-severity outcomes, such as death and permanent disability. These results provide a validated predictive equation and identify critical risk factors, thereby offering a data-driven framework for prevention strategies. This comprehensive modelling approach bridges the gap between theoretical regression and practical safety decision-making.
