【摘要】：近二十年来,我国高速公路总里程不断攀升,高速公路运输已成为国民经济发展的支柱。与此同时,在高速公路上发生的交通事故日益增多,给国家和人民也造成了巨大的损失。这使得高速公路成为一把双刃剑,有利也有弊。那么,如何利用好这把剑,将弊降至最低限度已亟待我们解决。即科学地、全面地、系统地分析高速公路事故频发的原因,展开高速公路交通安全评价研究,提出相应工程技术措施,以达到减少交通事故或降低交通事故受害程度的目标等相关交通安全的研究迫在眉睫。本论文首先以系统、全面地观点对影响高速公路交通安全的人、车、路和环境等因素及其相互作用进行了分析,围绕“人一车一路一环境”系统提出了高速公路交通安全评价指标体系,运用层次分析法得出各评价指标权重。其次,基于将高速公路交通安全评价问题归结为“对事物属性定性描述进行定量化研究的问题”这一思想,依据属性识别理论知识,建立高速公路交通安全属性综合评价模型。在确定了单指标测度值、综合属性测度值,选取置信度后,就可以进行属性识别,得出评价结果。然后,将此模型应用于京港澳高速公路湖北咸宁段进行交通安全评价,并与此段高速公路实际交通状况调查结果进行对比,以此来检验该模型的合理性。最后,根据高速公路交通安全评价结果,分析事故发生原因并提出相应地交通安全工程措施。
[Abstract]:In the past twenty years, the total mileage of expressway in our country has been rising continuously, the expressway transportation has become the pillar of the national economy development, at the same time, the traffic accident on the expressway is increasing day by day. To the country and the people have also caused huge losses. This makes the highway become a double-edged sword, there are advantages and disadvantages. So, how to make good use of this sword, to minimize the harm has to be solved urgently. That is, scientific. Comprehensively and systematically analyze the causes of the frequent accidents on the freeway, carry out the research on the evaluation of highway traffic safety, and put forward the corresponding engineering technical measures. In order to reduce traffic accidents or reduce the degree of traffic accident injury and other related traffic safety research is urgent. First of all, this paper systematically and comprehensively analyzes the human, vehicle, road and environment factors that affect the highway traffic safety and their interaction. The evaluation index system of expressway traffic safety is put forward based on the system of "one vehicle, one road, one environment", and the weight of each evaluation index is obtained by using the analytic hierarchy process (AHP). Secondly, based on the thought that the problem of highway traffic safety evaluation is "the problem of qualitative description of things", the theory of attribute recognition is based on the theory of attribute recognition. The comprehensive evaluation model of freeway traffic safety attribute is established. After determining the single index measuring value, synthesizing attribute measure value and selecting confidence degree, the attribute identification can be carried out and the evaluation result can be obtained. Then, the model is applied to the traffic safety evaluation of Xianning section of Beijing-HongKong-Macao expressway in Hubei province, and compared with the investigation results of the actual traffic situation of this section of expressway, so as to test the rationality of the model. Finally, according to the evaluation results of expressway traffic safety, the causes of accidents are analyzed and corresponding traffic safety engineering measures are put forward.
