This study evaluates the risks associated with irregular occupations near railroads. The research instrument was developed using the Best-Worst Scaling technique. Data were collected from a panel of experts representing various sectors, including academia, government, and the railway companies. The panelists completed a questionnaire to assess the risks associated with occupations around Brazilian railroads. Using discrete choice models based on a multinomial logit structure, the relative importance of different risk variables in railway operations was examined in relation to surrounding occupations. The results show that the risks of being struck by trains and derailments are the most critical and demand immediate mitigation efforts, such as installing safety barriers, enhancing level crossing signals, and controlling access to tracks. The study also highlights that areas with high population densities near railroads require priority interventions, including improvements in drainage systems and monitoring the geotechnical stability of slopes and embankments. In contrast, unoccupied areas were identified as lower-risk zones, emphasizing the importance of preventing new construction in these regions to maintain the safety and efficiency of rail operations.
