摘　　要：山区高速公路是西部地区道路运输网络中的重要干线系统,其内部交通安全影响因素较多、各因素之间关系复杂,考虑到这些因素之间的模糊性以及不确定性,从道路条件、行车环境、交通安全设施以及管理手段等方面着手,引进范数灰关联度概念对各影响因素进行客观赋权,利用同一、差异、对立的集对分析理论对影响山区高速公路路段安全性的主要因素进行等级划分,进而结合权重值得出山区高速公路不同路段的安全等级。方法避免了高速公路路段安全性评估中的不确定因素的影响,得到较为客观的评价结果。实例评价结果表明,该方法能够准确反映山区高速公路各路段安全性程度,能够为高速公路管理部门提供决策依据。Mountainous expressway is an important trunk road system in western region where the topography is complex and fog weather is frequent. Taking into account of following factors such as the complexity of traffic flow and fog conditions, the traffic safety facilities at different sections of mountainous areas, and different smooth flow levels, and based on entropy fuzzy matter element theory, this paper selects some major factors affecting mountainous expressway traffic safety, and uses information entropy empowerment theory to endow each factor value, and incorporates objective weights and expert＇s subjective weights into consideration. By using matter element analysis method, membership function is applied to get safety classification results for different sections of mountainous freeway. Examples show that this method can promptly and accurately reflect the safety degree of mountainous highways and can provide a timely decision-making basis for management departments.
