高速公路上的交通堵塞或高峰时间车站里的人群是吸引了许多科学家注意的社会现象。已知的是，S op-and-go波是在与车辆或行人的移动相反的方向上传播的簇波。城市是由许多道路和交叉口以网络的形式组成的，走走停停的波会沿着道路网络传播。因此，在考虑交通拥堵时，需要从更广泛的角度进行观察，分析道路之间的相互联系。在本研究中，我们使用基于图的控制方法，并定义一个图形形状的交通网络，考虑到交通流的特性。我们将稳态作为网络的初始条件，并有意地在某条道路上制造交通堵塞。在拥堵之后，我们展示了交通拥堵波传播的方式，并讨论了它从一条道路传播到连接道路的机制。这也显示了交通阻塞的传播和减少的情况，模拟结果与定量积分的理论值相对应。这将有助于解决交通拥堵问题。
Traffic jams on highways or crowds of people in stations during rush hours are social phenomena that have attracted the attention of many scientists. It is known that the s op-and-go waveis a cluster wave that propagates in a direction opposite to the movement of vehicles or pedestrians. A city consists of many roads and intersections in the form of a network, and the stop-and-go wave will propagate according to the road network. Therefore, observations need to be made from a broader perspective to analyze the interconnections between roads when considering traffic congestion. In this study, we use a graph-based control method and define a graph-shaped traffic network considering the characteristics of traffic flow. We set the steady state as the initial condition in the network and create a traffic jam on a certain road intentionally. Following the congestion, we show the manner in which the traffic congestion wave spreads, and discuss the mechanism in which it propagates from one road to a connecting road. This also shows the kind of situations in which traffic jams propagate and diminish; the simulation results correspond to the theoretical value integrated quantitatively. This will be helpful in solving the traffic congestion problem.
