Abstract：
Objective: The division of responsibility in vehicle-two-wheelers accidents reflects the extent to which different fault parties contributed to the occurrence of the accident, with significant differences in the injuries sustained by the riders in accidents where diverse parties were primarily responsible. We want to explore the difference in the severity of injury of riders in different fault parties of accidents so that we can make targeted protection improvements.Methods: In this study, three generalized ordered logit models were established for the total sample (n = 1204), the sample with drivers as the primary fault party (n = 607), and the sample with riders as the primary fault party (n = 597), respectively, to explore the differential impact factors on rider injury severity in vehicle-two-wheelers accidents involving different fault parties. Inter-group difference tests were conducted on the mean rider injury severity caused by differential factors in different accidents. Combining the impact effect trends and mean differences in the model, the differences in rider injury severity in accidents involving different fault parties were analyzed from the standpoints of human, vehicle, and road factors.Results: It was found that the effects of curve on injury severity was sheerly opposite in accidents with different fault parties and that factors, such as visual obstruction, road surface condition, gender, and helmet wearing differed in their effects on rider injury severity under different fault parties accidents. This reveals the driving tendencies and states of both parties in different environments.Conclusion: Based on the differential impact factor analysis and rider injury characteristics in accidents involving different fault parties, suggestions for improvement were made from the perspectives of road facilities, and safety awareness of drivers and riders, which are beneficial for improving rider safety and providing a theoretical reference for future regulations on liability allocation.
摘要：
目的:车辆两轮车事故中的责任划分反映了不同过错方促成事故发生的程度,在不同方负有主要责任的事故中，骑手所遭受的伤害存在显著差异。我们想探讨不同事故过错方骑手受伤严重程度的差异，以便有针对性地进行保护改进。方法:在本研究中,对总样本(n=1204)建立了三个广义有序Logit模型，以驱动程序为主要故障方的样本(n=607)，以及以骑手为主要故障方的样本(n=597)，分别,探讨涉及不同故障方的两轮车事故中骑手受伤严重程度的差异影响因素。对不同事故中差异因素造成的平均骑手受伤严重程度进行组间差异检验。结合模型中的影响效应趋势和均值差异，从人的角度分析了不同故障方事故中骑手受伤严重程度的差异，车辆,和道路因素。结果：发现曲线对损伤严重程度的影响在不同故障方的事故中完全相反，比如视觉障碍，路面状况,性别,在不同的故障方事故下，头盔佩戴对骑手受伤严重程度的影响不同。这揭示了双方在不同环境中的驾驶趋势和状态。结论:基于不同过错方事故中不同影响因素分析和骑手伤害特征,从道路设施的角度提出了改进建议，以及司机和乘客的安全意识，有利于提高骑手的安全性,为今后的责任分配法规提供理论参考。
