Research on Causes of Hazardous Chemicals Road Transportation Accidents Based on Social Network Analysis Method
To clarify the causes of hazardous chemicals road transportation accidents and the relationship between them,the accident causing 24Model was used to analyze the text of 155 cases of hazardous chemicals road transportation accidents from 2019 to 2023.The social network analysis (SNA)software method was used to establish accident causing network of hazard-ous chemicals road transportation accidents. The network centrality,core-periphery structure and cohesive subgroups were analyzed. The results show that among the 30 accident-causing factors,14 factors are located in the core area of the accident-causing network. Factors such as improper operation,special road section,speeding,distracted attention and poor security awareness,play a major role in the occurrence of accidents. Five cohesive subgroups are formed in the causing network,and there is a close relationship between the cohesive subgroups and the causing factors within the cohesive subgroups. The research results can provide a theoretical basis for improving the safety management level of hazardous chemicals road transportation.
