Abstract: Railway dangerous goods possess complex hazardous characteristics. The strong coupling effect exists among vehicles, goods and environment during transportation. This effect leads to a continuous increase in the risk of major accidents. This paper employs the structural equation model to analyze the coupling relationship among vehicles, goods and environment in the transportation of Class 4 railway dangerous goods, which is a typical high-risk category. The model takes the internal environment of the vehicle, vehicle performance, goods attributes and external environment as latent variables. It also uses 19 quantitative indicators as observed variables. The model calculates the interaction relationships of the latent variables and identifies the key influencing factors during transportation. The coupling coordination model is used to evaluate the coupling coordination level of the "vehicle-goods-environment" system. The research shows that there are significant positive correlations among the internal environment of the vehicle, vehicle performance, goods attributes, and external environment. The correlation between the internal environment of the vehicle and vehicle performance is the greatest, with a path coefficient of 0.87. The wind force, humidity and vibration are key factors for transportation. The coupling coordination degree of the system D=0.750, which is at the intermediate coordination level. During transportation, in order to reduce the risk of coupling resonance, the above three factors should be monitored in real time. The vehicle type and speed should be reasonably matched. And the packaging should be strengthened to achieve shock absorption and moisture control. [ABSTRACT FROM AUTHOR]
