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.
