A new safety culture model is constructed and is applied to analyze the correlations between safety culture and SMS.On the basis of previous typical definitions,models and theories of safety culture,an in-depth analysis on safety cultures structure,composing elements and their correlations was conducted.A new definition of safety culture was proposed from the perspective of sub-culture.7 types of safety sub-culture,which are safety priority culture,standardizing culture,flexible culture,learning culture,teamwork culture,reporting culture and justice culture were defined later.Then integrated safety culture model(ISCM) was put forward based on the definition.The model divided safety culture into intrinsic latency level and extrinsic indication level and explained the potential relationship between safety sub-culture and all safety culture dimensions.Finally in the analyzing of safety culture and SMS,it concluded that positive safety culture is the basis of implementing SMS effectively and an advanced SMS will improve safety culture from all around.
