【摘要】 为定量评估道路危货车辆运输违规情况,采用熵权法计算权重,TOPSIS法对各月指标进行宏观纵向排序,灰色关联分析法横向分析子序列与母序列关联程度,从而建立一个综合评价模型,并以陕西省道路危货车辆运输违规情况进行实证研究。结果表明:通过陕西省政府和企业监管力度加大,较好的规范了危险品道路运输操作,违规报警次数整体上呈现递减趋势,安全性逐步提升。所监测各子序列与母序列关联程度都较大,其中,疲劳驾驶对报警影响最大,离线位移影响最小。根据研究结果提出改进建议,降低道路危货车辆运输违规操作次数,提高道路危险货物运输安全性。更多还原

【Abstract】 In order to quantitatively evaluate the traffic violations of road dangerous goods vehicles,the entropy weight method was used to calculate the weight the TOPSIS method was use to perform a macroscopic and vertical ranking of the indicators of each month and the gray correlation analysis method was used to horizontally analyze the degree of association between subsequences and parent sequences. Thus,a comprehensive evaluation model was established. An empirical study was conducted on the violation of road dangerous goods vehicles in Shaanxi Province. The results show that through the increase of the supervision of Shaanxi provincial government and enterprises,the operation of dangerous goods road transportation has been well standardized and the number of violation alarms shows a decreasing trend on the whole,and the safety is gradually improved. The sub-sequences monitored have a high degree of correlation with the parent sequences.Among them,fatigue driving has the greatest impact on the alarm and the offline displacement has the least influence.According to the research results,suggestions for improvement are proposed to reduce the number of illegal operation of road dangerous goods vehicles and improve the safety of road dangerous goods transportation.更多还原
