Abstract:

To prevent tunnel workers' unsafe behaviors, the effects of workers' cognitive biases on their unsafe behaviors and the role of risk perception in this process were investigated. Based on the literature, a conceptual model describing the relationship between workers' cognitive bias, risk perception, and unsafe behaviors was proposed. Moreover, measurement scales in tunnel construction scenarios were designed and a questionnaire survey was conducted. Then, the proposed conceptual model using regression analysis was used to investigate the effects of workers' cognitive bias on their unsafe behaviors. The results showed tunnel workers' cognitive bias positively affected their unsafe behaviors (effect value=0.713) and negatively impacted their risk cognition (effect value=-0.607). Workers' risk cognition negatively affected their unsafe behaviors (effect value=-0.617) and partially mediated the relationship between workers' cognitive bias and their unsafe behaviors (effect value=0.334).

Key words: tunnel workers, cognitive bias, unsafe behaviors, risk perception, mediating effect, regression analysis
