Abstract: 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 stop-and-go wave is 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. (More)
