To have a deep understanding of the causal relationship between crane drivers' situation awareness information and behavior,the situation awareness and behavior response model of crane drivers was proposed by combining the ENDSLEY situation awareness model with the DEMATEL-AISM method. Firstly,the situation awareness theory was used to analyze the driver's behavioral response process and obtain information factors during the crane operation task. Secondly,the DEMATEL method was used to quantitatively analyze the association between the factors and determine a comprehensive influence matrix. Moreover,the attributes and characteristic values of the factors were analyzed to identify the key factors. Finally,a stable hierarchical structure of cause-effect attributes obtained by the AISM was used to propose the situation awareness and behavior response model of crane drivers. The results revealed that a five-layer information model consisted of 22 elements and influence relationships such as key elements of trajectory prediction and planning,and collision avoidance. Furthermore,the proposed model clarified the attribute characteristics,influence relationships,and influence degree among the information elements,offering a deep understanding of the crane driver's situation awareness and behavior response.
