| 摘 要： | 利用新疆高等级公路的事故资料,分析了这些公路事故的发生与气象因素之间的关系,并据此建立5个依次递升的交通安全气象因素预警等级.在此基础上,将熵值法与模糊物元建模相结合,应用熵值法来确定权重系数,避免了权重系数确定的主观性问题,同时结合所建立的气象影响因素安全评价指标体系,对高等级公路沿线的主要站点进行了气象影响因素的安全评价,最终得出当日气象因素对公路交通安全影响的评价等级.

| Abstract: | Based on traffic accident data for high-grade highway in Xinjiang,the relationship between traffic accidents and meteorological factors was analyzed and evaluation grade was determined.Fuzzy matter-element model based on entropy weights and combined with the establishment of the influence assessment index system was appliedto judge the influence grades of meteorological factors on the traffic safety of the main stations distributed along high-gradehig hway in Xinjiang. |

| Keywords: | high-grade highway meteorological factor fuzzy matter-element entropy weight safety evaluation |
