Unsafe human behavior at construction sites

As the construction industry is one of the most dangerous ones, it is of great importance to understand the unsafe human behavior at construction sites. Over the past decades, construction stakeholders have made various efforts to improve construction safety from different perspectives, such as enacting safety-related laws and regulations and developing safety management systems. Despite these efforts, safety is still one of the challenges in the sector. As construction workers are the main causes to and the victims of accidents, the control of their unsafe behavior requires more attention. Nevertheless, this control process is never an easy task as their unsafe behavior shows various characteristics and is influenced by numerous factors. Therefore, the unsafe human behavior control is still the primary challenge in the construction safety management field. The mechanisms of unsafe human behavior at construction sites can be analyzed from the following aspects: （1）Unsafe human behavior is affected by various factors (e.g., perception and cognition, emotion, stress and mental fatigue, social interactions), and the influences of these factors on unsafe behavior may be nonlinear. （2）Unsafe human behavior is scenario-based, which mainly involves their attributes and objectives, environmental and realistic basis, and the interaction and game with other stakeholders. （3）Unsafe human behavior has adaptive and dynamic evolution characteristics, and adaptability creates complexity. People can adjust their safety behavior related decisions through learning, imitation and attempting based on their attributes and external environment. This Research Topic focuses on the influencing factors, complexity mechanism, dynamic evolution and adaptability, and preventive strategies of unsafe human behavior in the construction industry. Contributions on other important worker-safety domains, such as industry and agriculture machine workers, will also be considered. In addition to original research articles, we also welcome case studies, perspectives, hypothesis and theory articles, reviews, and methods as contributions to this Research Topic.
