【摘要】：鉴于山区地形起伏较大，地质、气象条件复杂，山区高速公路存在运行环境复杂、事故易发路段较多等安全问题。山区地区高速公路重、特大交通事故发生率及死亡率均远高于平原地区高速公路。因此，开展特殊事件下山区高速公路安全运行管理研究，对降低山区高速公路事故率，保障道路车辆安全运行具有重要意义。本文针对特殊事件对山区高速公路安全运行的影响，首先介绍了山区高速公路特殊事件的特征，其次从线形件、构造物、路面状况、路网环境及交通特征等方面来分析山区高速公路的运行环境，最后基于三种特殊事件，分别讨论其对山区高速公路交通运行的影响。本文通过对监测信息的用户主体和不同用户的监测需求两个方面分析得出，环境信息监测、交通流相关参数监测、事件监测是山区高速公路信息监测的主体。进而为得到用户所需监测信息，分别针对行车环境、交通事件、地质灾害制定运行环境监测指标，并根据不同指标采集时所需监测器的布设制定监测技术方法。最终从监测器技术和监测器布设两个方面制定山区高速公路运行技术标准要求。本文根据特殊事件的特性及特殊事件对山区高速公路交通运行的影响程度，将不同类型的特殊事件划分为不同等级，通过分析以工程对策与交通管理对策相结合的运行管理策略，针对不同类型、等级的特殊事件分别制定出与该特殊事件相对应的分级运行处置预案，，并给出各级特殊事件的运行处置流程。本文旨在能正确选择特殊事件发生后，山区高速公路的疏导与控制策略，深入分析疏导与控制技术的应用特性及措施间关系，并进行最优措施决策。通过研究疏导路网、疏导节点的确定，构建了基于多路径随机用户均衡交通分配模型（SUE）的疏导模型。通过研究特殊事件下山区高速公路匝道控制特点、路段通行能力估计，构建了基于线性规划模型的匝道出入口模型。最后，采用层次分析法——模糊综合评价模型对特殊事件下山区高速公路运行管理效果进行综合评价。
[Abstract]:In view of the large topography, geology and complex meteorological conditions in mountainous areas, there are many safety problems such as complex operating environment and more accident prone sections of expressway in mountainous areas. The incidence and mortality of serious traffic accidents in mountainous areas are much higher than those in plain areas. Therefore, it is of great significance to carry out the research on the safe operation management of expressway in mountainous area under special events to reduce the accident rate of expressway in mountainous area and to ensure the safe operation of road vehicles. In view of the influence of special events on the safe operation of mountain expressway, this paper first introduces the characteristics of the special events of mountain expressway, and then from the line, structure, road condition, The network environment and traffic characteristics are analyzed in this paper. Finally, based on three kinds of special events, the influence on the traffic operation of mountain expressway is discussed respectively. Based on the analysis of the user subject of monitoring information and the monitoring needs of different users, this paper concludes that environmental information monitoring, traffic flow related parameters monitoring and event monitoring are the main body of mountain highway information monitoring. Then, in order to obtain the monitoring information required by users, the operating environment monitoring indexes are developed for the traffic environment, traffic events and geological hazards, and the monitoring techniques are developed according to the required monitors when different indexes are collected. Finally, from two aspects of monitor technology and monitor layout, the technical standard requirements of mountain highway operation are formulated. According to the characteristics of special events and the influence of special events on the traffic operation of highway in mountainous areas, different types of special events are classified into different grades in this paper. By analyzing the operation management strategy which combines engineering countermeasure with traffic management strategy, according to the special events of different types and grades, the corresponding classified operation and disposal plan of the special event is worked out. At the same time, the operation and disposal flow of special events at all levels are given. The purpose of this paper is to correctly select the strategy of guidance and control of expressway in mountainous area after the occurrence of special events, to analyze the application characteristics of dredging and control technology and the relationship between measures, and to make the optimal decision of measures. Based on the study of the road network and the determination of the grooming nodes, a grooming model based on the multipath stochastic user equilibrium traffic assignment model (SUE) is constructed. A ramp exit model based on linear programming model is constructed by studying the characteristics of ramp control and the estimation of traffic capacity of expressway in mountainous area under special events. Finally, the paper uses the analytic hierarchy process (AHP)-fuzzy comprehensive evaluation model to evaluate the operation and management effect of expressway in mountainous area under special events.
