Abstract:

An improved DEMATEL-AISM method combined Decision Making Trial and Evaluation Laboratory (DEMATE) with Adversarial Interpretative Structural Model (AISM ) was proposed to explore the relationship between factors influencing accidents involving heavy-duty trucks and two-wheelers. Combined literature analysis method and the National Automobile Accident In-depth Investigation System (NAIS) data (China), an index system of accident causes was established. According to the characteristics of accident data, the DEMATEL method was improved to analyze the influence degrees between accident factors. Based on AISM, the topological hierarchy model of accident factors was established to analyze the topological variability of accident system and the interaction of factors. The results show that the effect of overload on other factors is only 0.150 in the heavy-duty truck and two-wheeler accidents. Among resulting factors, the decision failure is the critical factor easily influenced with a centrality of 5.25 and an influence of 5.18. The accident system is an active system, with the occurrence of accidents being affected by a combination of the driving layer, the direct layer and the intermediate layer factors.

Key words: road traffic safety, heavy-duty truck and two-wheeler accidents, cause analysis, topology hierarchy structures, decision making trial and evaluation laboratory (DEMATEL), adversarial interpretative structural model (AISM)
