Abstract:
Although workers’ unsafe behaviors are the main causes of accdients in construction projects, there is a noticable lack of research addressing the mechanisms of workers’ safety behavior. In this paper, an agent-based model that integrates the cognitive process of safety behavior and workers’ interactions with the environment—including coworkers, management, and site condition—has been constructed. Then, model experiments were conducted to investigate the effects of the strictness and cohesiveness of management feedback on safety behavior. The results indicated that while the strictness has significant impacts on reducing workers’ unsafe behaviors, the impacts become limited in specific conditions; 1) lenient feedback in the modest-risk condition; 2) whole range of the strictness in the low-risk condition except for very strict feedback; and 3) very stict feedback in high-risk conditions. Also, it was found that construction managers should achieve at least a medium level of cohesiven
ess in feedback in order to prevent the negative impacts of the low cohesiveness of management feedback. This paper contributes to the body of knowledge on construction safety as well as simulation literature by developing the socio-cognitive process model of workers’ safety behavior that examines how the socio-cognitive process interacts with management and the site condition.
