摘要: 为了揭示车辆排队形成的多米诺效应,基于运动学起动一停车波模型构造了车辆排队位置确定模型.该模型能实时确定路网中任意车流形成的排队队列的头部位置、尾部位置和队列长度.根据该模型以及车流间的相互作用,以任意相邻的两个交叉口为例,分10种情况讨论了下游车流能否对延续车流或冲突车流造成阻滞作用,并进而引起网络效应.结果表明,相邻路段车辆排队之间的耦合关系是研究网络效应的核心.

Abstract:

In order to reveal the domino effect resulting from the vehicle queuing, a determination model of vehicle queuing location is constructed based on the kinetic start-stop wave model, which can real-timely decide the head location, the end location and the length of any queue in a traffic network. Then, according to the model and the correlation among vehicle flows, two random neighbor intersections in 10 conditions are taken to reveal whether the downstream flow blocks the upstream flow or the conflicted flow and further results in the domino effect. The results demonstrate that the coupling of vehicle queues on neighbor segments constitutes the core of the domino effect in a traffic network.

Key words: traffic conflict, congestion, jam, vehicle queuing location, domino effect
