【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。更多还原

【Abstract】 Because of Mountainous terrain’s fluctuation, the complex geological andmeteorological conditions, the operation environment of highway in mountainous terrainexists safety problems, such as complex running environment, more accident-prone sectionand so on. Fatal traffic accidents、extraordinarily serious traffic accidents’ incidence rates ormortality rates in mountainous terrain is all much higher than highway in plain area. So,Carrying out research about the safe operation management under the special events ofhighway in the mountainous area is of great significance for reducing the mountainous area’shighway accident rates, and ensuring the safety of road vehicle running.Aiming at effects of special events on the safe operation of highway in mountainous area,this paper, in the first, introducing the characteristics of mount-ainous highway’s specialevents, secondly, analyzing the running environment of mountainous highway from the linear,structure, road conditions, network environment and traffic characteristics and so on, finally,based on three kinds of special events, respectively discussing its the influence of highway inmountainous area’s traffic operation.This paper draws a conclusion by the analysis of the principal part of monitoring users anddifferent monitoring users’ needs, that environmental information monitoring, traffic flowparameters monitoring, event monitoring are principal part of mountainous highwayinformation monitoring. Furthermore,in order to obtain monitoring information required bythe user, the environmental monitoring indicators is developed by driving environment,traffic incidents, geological disaster respectively, and according to the monitor layout requiredby different indicators acquisition establish the methods of monitoring technology. Ultimatelymountainous highway running technical standards is formulated from two aspects of themonitor techniques and the monitor layout.Based on the characteristics of special events and the degree of influence of specialevents operating on the mountainous highway traffic, different types of special events will bedivided into different levels,through the analysis of operational management strategies whichcombines engineering measures and traffic management strategies, make the correspondingclassification operation disposal program to different types and grades of special events andgive the operation disposal process for various special events.The purpose of this paper is to correctly select the guidance and control strategy ofmountainous area highway after the special incident, In-depth analysis the relationshipbetween the guidance and control technology application characteristics and measures, andmakes the optimal measures. By studying the channel network, the determination ofpersuation nodes, building the channel model based on the multipath stochastic userequilibrium traffic assignment model (SUE).Through researching the mountain area highwayramp control characteristics and the evaluation of road traffic capacity behind special event,building the ramp gateway model based on linear programming model.Finally, using the analytic hierarchy process (AHP), fuzzy comprehensive evaluationmodel to evaluate the effect of mountain area expressway operation and management behindspecial event.更多还原
