【摘要】：高速公路网的形成和完善,己成为当前道路交通运输体系的重要组成部分。一旦发生重大交通事故,必将对区域路网交通产生很大影响,降低高速公路通行效率和运行安全,甚至衍生二次交通事故、环境污染以及能源浪费等问题。事故条件下高速公路网应急交通组织对于降低高速公路交通事故的影响,防止二次事故的发生具有重要意义。论文结合交通事故的演化特征,分析交通事故持续时间各阶段的影响因素及作用机理,构建交通事故持续时间分阶段预测模型。分析交通事故对高速公路网交通运行的影响,探讨交通事故影响空间扩散的关联因素与扩散状态,提出交通事故分级方法,结合交通事故分级划分事故影响区,构建各影响区范围计算模型。明确高速公路网应急交通组织目标,归纳总结交通组织功能要求,设计应急交通组织决策框架,考虑不同影响区内交通组织对象与目标的不同,分别提出保护区、控制区和缓冲区应急交通组织策略。分析事故条件下封闭不同车道情况下保护区应急交通组织形式,结合交通组织形式剖析保护区车辆运行特征,基于Aimsun构建微观交通仿真模型,对不同交通组织形式下保护区合理限速值进行仿真模拟研究,从安全与效率两方面综合给出限速推荐值。分析事故条件下各类驾驶员的交通诱导信息需求,研究路网环境下交通诱导分流节点与路径的选取原则与方法,从路网整体运行效率的角度出发,提出交通诱导区域确定方法,制定交通诱导区域确定流程,并将所提方法应用于案例,验证方法的有效性。
[Abstract]:The formation and perfection of the highway network, has become an important part of the road transportation system. Once the occurrence of major accidents, will have a great impact on the regional traffic, reducing efficiency and safe operation of the highway traffic, even the two time derivative of traffic accidents, environmental pollution and waste of energy. Under the condition of highway emergency accidents to reduce the impact of traffic organization of expressway traffic accidents, prevent the occurrence of the two accident is of great significance. This paper combined with the evolution of traffic accident, traffic accident analysis of the influence of duration of each stage factors and mechanism, construction of the road traffic accident duration stage forecasting model. The analysis of traffic accident influence on traffic operation of expressway network, state to investigate the related factors and the diffusion of traffic accident influence spatial diffusion, the hierarchical method of traffic accident, Combined with the traffic accident classification effects of the accident area, calculation model of construction of the impact area. Clear the highway network emergency traffic organization, traffic organization summarizes the functional requirements, design of emergency traffic organization decision-making framework, considering different influence in the area of traffic organization and objects are different, respectively in this reserve, emergency traffic organization and control strategy buffer zone analysis. The emergency traffic organization form under the condition of different lanes closed to protect the accident case, combined with the analysis of the traffic organization of reserve vehicle operation characteristics, Aimsun construction of microscopic traffic simulation model based on reserve reasonable speed limit value under different forms of traffic organization simulation research, the recommended value from the two aspects of security and efficiency are comprehensive speed. Analysis of information needs of various types of driver's traffic induced accident conditions, research on road network traffic induction From the point of view of the overall operation efficiency of the road network, the method of determining the traffic guidance area is proposed, and the process of determining the traffic guidance area is formulated. The proposed method is applied to a case to verify the effectiveness of the method.
