Road construction sites are high-risk zones where safety must remain a top priority at every stage, from initial planning to final execution. This study aims to identify the main factors affecting safety performance on road construction sites by examining the perspectives of three key stakeholder groups: construction workers, engineers, and the public. To conduct this investigation, structural equation modeling (SEM) is used as the primary analytical tool. Data are collected through a large-scale questionnaire survey distributed among 4,500 respondents (1,500 from each group). The analysis focuses on seven major safety factors: personal protective equipment (PPE), signboards, safety training, communication, site inspections, traffic control measures, and environmental management. Among these, PPE, signboards, and traffic control emerge as the most influential in improving safety outcomes. These findings suggest that by giving priority to these areas, project teams and policymakers can significantly reduce accidents and foster a stronger culture of safety in road construction.
