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 emergency response capacity of highway network after traffic accident happening, reduce the time that regional road network is affected by traffic accident and lower the loss caused by traffic accident, the effective implementation of traffic guidance strategy is very necessary. This paper divided the traffic accident affected zone into three levels including nodes, lines and areas, and applied quantitative method to accident affected areas from nodes, lines and areas level and the method is respectively presented by setting experience and requirements of construction control area of highway maintenance, flow theory, comparison method between path impedance calculation and travel time. The paper divided and optimized the road nodes of traffic affected area from nodes, lines and areas level according to the induced point, the control point and the compulsory point. The induction nodes at all levels in regional road network were found, and the feasibility of the method was verified, based on the analysis on the accident situation of Hangjinqu Highway (Hangzhou-Jinhua-Quzhou). The results show that the accident affected zone can be determined quickly, based on the regional highway network topology, and combined with the traffic volume, vehicle speed, traffic capacity data and analysis on traffic accident scene. The proposed method can put forward the traffic control strategy hierarchically corresponding to the optimized road network nodes. Therefore, the efficiency of the disposal of the accident is improved.
