【摘要】：为了提升交通事故发生后高速路网对突发事件的应对能力,减少区域路网受交通事故影响的时间,降低交通事故带来的损失,开展交通诱导策略研究。将交通事故的影响范围按点、线、面3个层次进行划分,分别利用公路养护施工控制区设置经验及规范要求、交通流理论、路径阻抗计算与行驶时间对比的研究方法,定量确定点、线、面3个层次的事故影响区。按诱导分流点、管制诱导点和强制诱导点3种级别划分和优选点、线、面事故影响区内的道路节点。以杭金衢(杭州—金华—衢州)高速公路事故为例进行分析,找到区域路网内的各级诱导节点,验证了研究方法的可行性。研究结果表明:在区域高速路网拓扑关系的基础上,结合其交通量、车速、通行能力数据以及交通事故现场状况分析,能快速确定事故影响区范围;采用提出的方法可分层次针对优选路网节点提出交通控制策略,提高了事故处置效率。
[Abstract]:In order to improve the ability of the highway network to deal with the emergency after the traffic accident, reduce the time that the regional road network is affected by the traffic accident, and reduce the loss caused by the traffic accident. The influence range of traffic accident is divided into three levels: point, line and surface, and the traffic flow theory is used to set up the experience and standard requirement of highway maintenance construction control area, respectively, the traffic flow theory, the traffic flow theory, the traffic flow theory, the traffic flow theory, the traffic flow theory, The research method of comparing path impedance calculation with driving time, quantificationally determining the accident affected area at three levels of point, line and plane, dividing and selecting points according to three levels of induced diversion point, control induced point and forced induced point, line, etc. Taking Hangzhou Jinqu (Hangzhou Jinhua-Quzhou) expressway accident as an example to find all levels of induced nodes in the regional road network, The feasibility of the research method is verified. The results show that based on the topological relationship of the regional highway network, combined with the traffic volume, speed, traffic capacity data and traffic accident site situation analysis, the impact area of the accident can be quickly determined; The proposed method can be used to improve the efficiency of accident disposal by putting forward traffic control strategy for optimal network nodes.
