摘要 交通事故下道路的通行能力和车辆排队长度等问题是交通事故分析的重要内容。笔者探讨了双车道公路交通事故持续期间的换道行为,分析了换道期间车流运行的状态,在此基础上,结合二流理论建立了双车道公路交通事故下当量排队长度的数学模型。最后对该模型进行了仿真分析和计算。 The traffic capacity of the highway and queue length of vehicles under the traffic accident are important to analyze the traffic accident.Firstly,the paper discusses the lane-changing during the traffic accident on the two-lane highway and analyzes the status of traffic flow during the Lane -Changing.Then it builds the equivalent queue length model for the two-lane highway under the traffic accident based on the two-fluid theory. Finally,it simulates and analyzes the model.
